RESUMEN

Purpose: To share examination findings of the lens capsule which may act as an indicator for malpositioned intraocular lenses (IOL). Setting: Single large multi-specialty private practice, Houston, Texas, USA. Design: Focused, observational case series. Methods: A review of pre-operative images of malpositioned single-piece IOLs with at least one haptic in the ciliary sulcus was conducted. The review included five cases who were referred to a single large multi-specialty private practice from June 2023 to December 2024 for an evaluation of posterior capsular opacification (PCO) and potential Nd:YAG capsulotomy. Findings: A total of five eyes which previously had undergone cataract surgery and were referred for Nd:YAG capsulotomy for PCO were identified on slit lamp examination to have capsular waves, defined as a centripetal and circumferential striated pattern of PCO that results from a fused anterior and posterior capsule with at least part of the IOL anterior to the capsule. While one eye exhibited transillumination defects and pigment dispersion, the remainder of eyes did not. In some cases, the capsular wave was the only clue to IOL malpositioning due to a small pupil. These eyes had single-piece IOLs with at least one haptic in the sulcus and required subsequent IOL repositioning or exchange. Conclusion: If capsular waves are seen on slit lamp exam, a thorough inspection of IOL placement should be conducted, especially before treatment with Nd:YAG capsulotomy. Capsular waves result from anterior and posterior capsule contact with an anteriorly situated IOL. This finding is a potential indicator of at least part of an IOL positioned anterior to the anterior capsule.

RESUMEN

Purpose: To report two cases of neovascular glaucoma associated with Radium-223 infusion. Observations: Presented are two patients with metastatic prostate cancer who developed uncontrolled intraocular pressure secondary to neovascular glaucoma requiring surgical intervention. Both patients had received six cycles of Radium-223, a calcium mimetic that causes DNA double strand breaks and tumor cell death in bony metastases as part of their treatment regimen for metastatic prostate cancer. One patient had been a prior glaucoma suspect while the other had no significant ocular history. Conclusions and importance: Radium-223 may increase vascular permeability contributing to uveitis and promote angiostimulatory growth factors that can lead to neovascularization. We postulate this is through possible disruption in VEGF signaling pathways as well as Ra-223's calcium mimetic properties that could affect the trabecular meshwork. Neovascular glaucoma is uncommonly reported with Ra-223. There is one other case report that experienced uveitis and hyphema within weeks of the Ra-223 infusion. This case report has a similar proposed biologic mechanism. A literature review using the key words "radium-223, neovascularization, secondary angle closure glaucoma, neovascular glaucoma" did not yield any prior reports of neovascular glaucoma associated with Ra-223. The goal of this case series is to argue there is biological plausibility and to contribute to current literature of possible ocular complications of Ra-223 infusion.

RESUMEN

PURPOSE: The purpose of this study is to evaluate the epidemiological trends, primary ocular diagnosis, and degree of injury severity in pediatric patients after a toy-related ocular trauma. METHODS: A cross-sectional analysis was conducted using data from the National Electronic Injury Surveillance System Study (NEISS), encompassing patients who visited emergency departments over a 5-year period from January 1, 2017, to December 31, 2021, with toy-related ocular injuries. Descriptive statistics were employed using Microsoft Excel. RESULTS: Among the 1439 toy-related ocular injuries identified, the mean age of injury was 6.67 ± 4.36 years. The highest proportion of injuries occurred in the 2-5 years age group (27.2%). The NEISS database classified the severity of injury - the majority of which were minor anterior segment injuries. Toy guns with projectiles were identified as the most common type of toy associated with ocular eye injury. While most injuries were minor, a small percentage was severe. CONCLUSION: Age-appropriate toy selection and adult supervision during playtime are recommended preventive measures to mitigate the incidence and severity of traumatic eye injuries in children.

There is a risk of major ocular injury related to toys, especially toy guns/darts, in young children that requires intervention.However, the incidence of injuries related to toy guns has been stable for the last 40 years.Although most of these cases resulted in minor anterior segment injuries, patterns of serious injury can occur with toys.Physicians, educators, and parents should be made aware of the high risk of ocular toy-related injury when there is poor supervision, inadequate ocular protection, and a lack of understanding of toy-related risks to the eye.

RESUMEN

OBJECTIVE: To determine the causes, time to resolution, effect of therapeutics, and ocular sequelae of hyphema, fibrin, and/or vitreal hemorrhage in horses. ANIMALS: 225 horses (219 eyes) who were diagnosed with hyphema, fibrin, and/or vitreal hemorrhage. METHODS: Records were retrospectively reviewed for the horses. Signalment, ophthalmic examination findings, causes, treatments, and outcomes were evaluated. RESULTS: Common causes of intraocular fibrin or hemorrhage were equine recurrent uveitis (42/219 horses), corneal stromal abscess (32/219 horses), corneal stromal ulcer (25/219 horses), and trauma (21/219 horses). Eyes with fibrin that were treated with intracameral tissue plasminogen activator (TPA; n = 18 eyes) had significantly lower days to resolution (8.9 ± 12.6 days) compared to eyes not treated with TPA (28.3 ± 46.7 days). Ocular sequelae in horses with fibrin, such as cataracts (18/120 eyes), synechiae (11/120 eyes), and vision loss (17/120 eyes), were significantly less common in eyes treated with TPA. Sequelae in eyes with hyphema included cataracts (9/36 eyes), synechiae (6/36 eyes), and vision loss (5/36 eyes). Although 41 horses had an enucleation at presentation because of severe disease, 14/144 (< 10%) of horses with follow-up required an enucleation. CLINICAL RELEVANCE: The presence of blood products in the eyes of horses suggests severe ocular disease, but if the eye is not enucleated at presentation, the prognosis is good for maintaining the eye. Also, the use of intracameral TPA in horses with anterior chamber fibrin but not those with hyphema, results in less adverse ocular sequelae.

RESUMEN

Purpose: Although musculoskeletal involvement is the common presentation, studies have reported the incidence of sports related ocular trauma. Here we present the case reports of two patients who sustained injury in one of the fast growing sports - the pickleball, during play without eye protection. Observations: Two patients with history of injury during pickleball play presented to our clinic with varying spectrum of ocular presentations. First patient had an anterior segment involvement with hyphema and elevated intraocular pressure, and the second patient had both anterior and posterior segment involvement causing angle recession and commotio retinae. Conclusion: Ocular injuries related to various sports have been extensively described, our intent is to increase the awareness about the possible ocular injuries related to rising pickleball and that improved safety measures and appropriate education to the players could prevent such ocular injuries.

RESUMEN

Introduction: Uveitis-glaucoma-hyphema (UGH) syndrome is an infrequent but severe complication following intraocular lens implantation, characterized by anterior chamber inflammation and elevated intraocular pressure (IOP). This report presents a rare case of late-onset UGH syndrome induced by a well-positioned 1-piece posterior capsular intraocular lens (PCIOL) with a bulb of the haptics extruding through a peripheral capsular tear in a 90-year-old female, 17 years post-cataract surgery. Case Presentation: The patient presented with persistent blurred vision, recurrent anterior uveitis, and uncontrolled IOP despite medical therapy. Extensive evaluation, including ultrasound biomicroscopy, failed to identify the underlying cause, necessitating surgical intervention to control IOP. During concurrent goniotomy and canaloplasty, a PCIOL haptics was discovered protruding through a peripheral capsular tear, establishing the diagnosis. Following PCIOL-haptic amputation and goniotomy and canaloplasty, the patient experienced significant improvement in symptoms and IOP control, with complete resolution of UGH syndrome. Conclusion: This case highlights the necessity of considering atypical causes in persistent postoperative uveitis and IOP elevation and emphasizes the role of surgical intervention in managing complex cases.

RESUMEN

Purpose: To report the first case of uveitis-glaucoma-hyphema (UGH) syndrome post implantable collamer lens (ICL).Methods: Case reportResults: A 41-year-old female presented to our clinic complaining of bilateral eye pain and redness for two weeks. Her past medical history was significant for ICL, in both eyes and multiple sclerosis controlled with treatment. She had a long-standing history of bilateral recurrent uveitis and glaucoma. Ultrasound biomicroscopy revealed several sulcus cysts displacing the ICLs haptic into the ciliary body, leading to iris abrasion and uveitis-glaucoma-hyphema syndrome.Conclusion: We present the first published case worldwide about UGH syndrome secondary to ICL. This is an unusual complication, and measures can be taken to avoid it. This provides evidence of the importance of postoperative follow-up by the surgeon and appropriate work-up when such cases are suspected.

RESUMEN

BACKGROUND: The "C group" of the histiocytic disorders is characterized by non-Langerhans-cell histiocytic lesions in the skin, mucosal surfaces, or both, out of which Juvenile xanthogranuloma (JXG) is the most common typically affecting the skin. The eye is the most common extra-cutaneous site of JXG., we aim at providing our clinical and histopathological experience with this group of diseases including the adult-onset xanthogranuloma (AXG). METHODS: This is a retrospective cohort study of all patients with the tissue diagnosis of ocular and periocular cutaneous and mucocutaneous non-LCH disorders who presented to us over a period of 25 years (January 1993 to December 2018). RESULTS: Twenty patients were diagnosed as "Group C" disease with an age range of 2 months-60.9 years. Eleven patients were females (55%) and nine were males (45%). The involvement was mostly unilateral in 80.9%. All cases fell into the xanthogranuloma family with 11 JXG patients, 8 AXG patients of skin and ocular surface, and one patient with solitary reticulohistiocytoma (SRH). The clinical site of involvement in JXG was primarily in the eyelid in 5 patients (45%), ocular surface lesions in 2 (18%), iris in 2 (18%), choroidal and bilateral orbital lesions in 1 patient each (9%). The group of AXG, presented equally with eyelid lesions in 4/8 and ocular surface lesions in 4/8. The non-Langerhans' histiocytic infiltrate showed supportive immunohistochemical staining properties (reactive to CD68 marker and negative to S-100 and langerin markers). CONCLUSION: Among the rare histiocytic disorders, xanthogranulomatosis is the commonest and has wide clinical manifestations. Accurate diagnosis needs to be supported by typical histopathological findings. JXG was the commonest in our study with relatively older mean age at presentation and frequent eyelid rather than iris involvement. AXG is often confused with xanthelasma when involving the eyelids with corneal limbal involvement is relatively frequent.

RESUMEN

Purpose: To describe a case of retinal vaso-occlusive vasculitis with associated lid edema and conjunctivitis following intravitreal pegcetacoplan administration in a patient with geographic atrophy (GA). Observation: A 78 year old Caucasian woman presented with complaints of lid edema, conjunctival injection, loss of vision, and mild ocular discomfort eleven days after receiving an intravitreal pegcetacoplan injection in the left eye for geographic atrophy. Visual acuity on presentation was decreased to 20/400 from 20/200 previously in that eye. Eyelid edema and conjunctival injection were present with minimal anterior chamber reaction. Dilated fundus examination revealed hemorrhages throughout the retina and signs of retinal vasculitis. The patient subsequently developed hyphema and vitreous hemorrhage. Laboratory evaluations for common infectious and inflammatory causes including aqueous and vitreous cultures for bacteria and Herpes simplex PCR were normal or negative. A delayed hypersensitivity to pegcetacoplan was suspected and was treated with topical, oral subconjunctival and intravitreal steroids. Conclusion: This index report illustrates a case of retinal vaso-occlusive vasculitis associated with intravitreal pegcetacoplan associated with lid edema and conjunctival injection and subsequent hyphema and vitreous hemorrhage. Therapy with steroids topically, systemically, periocularly and intravitreally were used to treat the inflammatory process and prevent further visual loss.

RESUMEN

PURPOSE: To assess the risk for intraoperative and postoperative ocular bleeding associated with direct oral anticoagulant treatment in patients undergoing phacoemulsification surgery. METHODS: Consecutive patients had phacoemulsification and intraocular lens implantation while taking uninterrupted direct oral anticoagulants (dabigatran, rivaroxaban, or apixaban). Gender and age-matched patients without antithrombotic therapy were used as the control group. Patients were examined one week postoperatively. Intraoperative and postoperative hemorrhagic and non-hemorrhagic complications were assessed. RESULTS: Forty patients (56 eyes) on direct oral anticoagulants and 120 patients (172 eyes) without anticoagulation, at a mean age of 77 years, had phacoemulsification. There was no significant difference between the groups in the rate of intraoperative and postoperative bleeding. One eye (1.8%) in the treatment group and 3 eyes (1.7%) in the control group had hyphema (p = 0.72). No patient had thromboembolic event during or after surgery. CONCLUSIONS: Cataract surgery was safely performed while continuing direct oral anticoagulation.

RESUMEN

Introducción: El glaucoma es una de las entidades nosológicas con mayor prevalencia y constituye una de las principales causas de ceguera en el mundo desarrollado. La presión intraocular es el único factor de riesgo que puede ser controlado y se asocia a la presencia y progresión de la enfermedad. Objetivo: Describir la evolución de pacientes operados mediante la técnica de trabeculectomía. Métodos: Se realizó un estudio observacional descriptivo, longitudinal y prospectivo de 128 pacientes con glaucoma crónico simple operados mediante la técnica de trabeculectomía en el Centro Oftalmológico de Santiago de Cuba, desde enero del 2017 hasta junio del 2019. Para ello, se analizaron las siguientes variables: edad, sexo, color de piel, agudeza visual preoperatoria y posoperatoria, presión intraocular antes y después de la operación, así como complicaciones posoperatorias. Resultados: Predominaron el sexo masculino (69,5 %), el grupo etario de 60-69 años (44,5 %) y el color de la piel negro (53,1 %). La hipertensión arterial fue la enfermedad asociada con más frecuencia y la hipertensión ocular, el factor de riesgo fundamental; en tanto, la complicación posoperatoria principal fue el hipema. Conclusiones: Con la trabeculectomía se logró controlar la tensión ocular en la mayoría de los pacientes y las complicaciones que se presentaron en algunos de ellos no interfirieron en su evolución. Esta técnica permitió disminuir el daño irreversible que provoca la hipertensión ocular del nervio óptico y, por consiguiente, prevenir la ceguera.

Introduction: Glaucoma is one of the nosologic entities with more prevalence and constitutes one of the main causes of blindness in the developed world. The intraocular pressure is the only risk factor that can be controlled and is associated with the presence and progression of the disease. Objective: To describe the evolution of patients operated by means of trabeculectomy technique. Methods: An observational descriptive, longitudinal and prospective study of 128 patients with simple chronic glaucoma operated by means of trabeculectomy technique was carried out in the Ophthalmology Center of Santiago de Cuba, from January, 2017 to June, 2019. For this purpose, the following variables were analyzed: age, sex, skin color, preoperative and postoperative visual acuteness, intraocular pressure before and after the operation, as well as postoperative complications. Results: There was a prevalence of male sex (69.5%), 60-69 age group (44.5%) and black skin color (53.1%). Hypertension was the most frequent associated disease and the ocular hypertension was the fundamental risk factor; meanwhile, the main postoperative complication was the hyphema. Conclusions: With trabeculectomy was possible to control ocular tension in most of the patients and the complications that were presented in some of them did not interfere in their clinical course. This technique made it possible to reduce the irreversible damage caused by ocular hypertension of the optic nerve and, consequently, to prevent blindness.

RESUMEN

PURPOSE: We compared the 1-year surgical outcomes of microhook ab interno trabeculotomy (µLOT) using three types of microhooks. METHODS: We retrospectively analyzed 81 eyes that underwent µLOT, in which three microhooks, the Sinskey hook, Tanito Micro-Hook-trabeculotomy-device (TMH), and Matsushita ed. TMH, were used. We collected the data from the medical records. We analyzed the success rates and risk factors. Failure was defined as the need for additional surgery for IOP reduction, loss of light perception, and IOP ≧22 mmHg and IOP reduction <20% (definition 1), IOP ≧17 mmHg and IOP reduction <20% (definition 2), IOP ≧15 mmHg and IOP reduction <25% (definition 3), or IOP ≧12 mmHg and IOP reduction <30% (definition 4) at two consecutive follow-up visits. RESULTS: Twenty-six eyes underwent µLOT using the Sinskey microhook (group S), 21 eyes using the TMH (group T), and 34 eyes using the Matsushita ed. TMH (group M). The mean postoperative IOP and IOP-lowering medication score decreased significantly. The respective success rates among groups S, T, and M did not differ significantly (definition 1, 65.4%, 61.9%, and 55.9%; definition 2, 42.3%, 47.6%, and 32.3%; definition 3, 15.4%, 28.6%, and 23.5%; definition 4, 0%, 9.5%, and 2.9%). In group S, the hyphema-related IOP spikes decreased within 2 weeks postoperatively, and in group M, the non-hyphema-related IOP spikes decreased significantly. CONCLUSION: The 1-year surgical outcomes and complications after µLOT did not differ significantly among the three microhooks. The differences in the microhook tips might be associated with postoperative transient IOP spikes.

RESUMEN

OBJECTIVE: To examine the use of Carlevale IOL placement in patients with UGH, and to evaluate surgical outcomes. DESIGN: In this retrospective study, 28 patients with UGH syndrome that were subjected to IOL explantation and concomitant Carlevale IOL implantation were included in the study. METHODS: Information about VA, IOP, number of glaucoma medication, need for glaucoma surgery, presence of hemorrhage and inflammation were recorded up to 6 months after the procedure. RESULTS: We found a statistically significant increase in mean visual acuity and complete resolution of uveitis in all patients. Mean IOP and the mean number of glaucoma medications were significantly decreased postoperatively, while 14% of patients required additional glaucoma surgery. CONCLUSIONS: IOL explantation and concomitant Carlevale IOL implantation may provide a viable solution for UGH syndrome resolution, increases visual acuity, and decreases the need for glaucoma medication.

RESUMEN

PURPOSE: Minimally invasive glaucoma surgery is safer and effective surgical modality for patients with glaucoma. To compare the effect of axial length (AL) on the surgical outcomes of combined cataract surgery and ab interno trabeculotomy (phaco-LOT), a retrospective, non-randomized comparative study was performed. METHODS: In total, 458 eyes of 458 open-angle glaucoma patients who underwent phaco-LOT and were followed-up without any intervention for at least 6 months were enrolled. All were divided into a long-AL group (AL ≥ 26.0 mm, 123 eyes) and a not-long-AL group (AL < 26.0 mm, 335 eyes). The principal outcomes were the changes in intraocular pressure (IOP) and medication scores. We also sought a correlation between postoperative IOP spike and hyphema. RESULTS: Significant postoperative reductions in IOP and medication scores were apparent in all subjects. The IOP reductions were significant at all timepoints in the not-long-AL group, but not until 1 month postoperatively in the long-AL group, and the IOP change was significantly lower in the long-AL group from postoperative day 1 to 3 months. On subanalysis of subjects by age, the microhook used, the pre-operative IOP, and the medication score, a significantly higher incidence of IOP spike was observed in the long-AL group in weeks 1 and 2 (both p < 0.05), but this did not correlate with hyphema status, implying that a different mechanism was in play. CONCLUSION: Phaco-LOT was effective regardless of AL, but the postoperative IOP decrease was lower and the early postoperative incidence of IOP spike was higher in long-AL eyes.

RESUMEN

We describe a rare case of Soemmering's ring-induced uveitis-glaucoma-hyphema (UGH) syndrome, caused by an undisplaced, in-the-bag intraocular lens (IOL) 16 years after implantation. The presenting symptoms were recurrent episodes of transient monocular vision loss, which prompted extensive unremarkable investigations. Ultrasound biomicroscopy (UBM) eventually revealed an enlarging Soemmering's ring contacting the posterior iris and causing UGH syndrome. This is a unique case because the IOL haptics remained in the bag. Anterior vitrectomy, Soemmering's ring extraction, IOL exchange to a 3-piece IOL, and implantation of a trabecular meshwork bypass microstent were performed. IOP control and both functional and structural stability were achieved long term. Soemmering's ring-induced UGH syndrome should be on the differential of a patient with previous cataract surgery and elevated IOP complaining of visual disturbances. Early diagnosis with UBM and surgical intervention may provide optimal outcomes.

RESUMEN

Objective: To investigate the epidemiological and clinical characteristics of sports-related eye injuries in China, as well as how they differ depending on the sport or other specific factor that caused them. Methods: Consecutive medical records from 2015 to 2019 of sports-related eye injuries from a standardized database in nine tertiary referral hospitals in China were retrospectively reviewed and analyzed. Results: A total of 377 eyes in 376 inpatients (mean age, 22.5 ± 7.3 years; men:women 15.4:1) were included. Soccer (46.8%), basketball (27.1%), and badminton (16.8%) were the top three sports that caused injury. Ball strikes (74.7%), physical collision (13.8%), and racket/equipment beating (9.0%) were the common specific causes of injury. Blunt force injuries (95.8%) and close globe injuries (95.1%) accounted for the majority of injuries. Open globe injuries occurred more in basketball (8.3%) than in other sports, mainly due to physical collision (12.8%) and racket/equipment beating (11.8%). Basketball (13.4%) or physical collision (21.3%) caused Zone I injuries more frequently than other sports. Soccer (60.5%) and basketball (54.6%) caused more injuries to the posterior segment of the eyeball than other sports, mainly due to ball strikes (96.6%). Badminton (69.8%) and racket beating (61.8%) caused more Zone II globe injuries than other sports. In badminton, the percentage of hyphema (85.7%), the most typical symptom of eye damage, and ultimate visual acuity (VA) ≥20/40 (88.9%) was the greatest. A final low vision score of (≤4/200) was observed in 10.6% of all participants, including three participants who had an eye removed due to rupturing. The final VA was positively correlated with the presenting VA (r = 0.421). Conclusion: Sports can lead to high proportions of ocular contusion injury and low vision. VA prognosis is closely related to initial VA following ocular sports trauma, which is directly determined by the causative sports and/or the specific causes. Effective eye protection is imperative to avoid or reduce visual impairments of sports participants.

RESUMEN

Purpose: To report on delayed-onset hyphema following intravitreal injection of dexamethasone implant Ozurdex® in eyes with a history of gonioscopy-assisted transluminal trabeculotomy (GATT). Observations: We describe two cases of hyphema occurring within one day following Ozurdex® implantation in eyes that had undergone GATT at least one year prior. One case responded well to medical management, while the other required anterior chamber paracentesis for intraocular pressure (IOP) control. Both patients achieved normalization of IOP following resolution of the hyphema, and have not had recurrence. Conclusions and importance: We propose that transient hypotony immediately after Ozurdex® injection may lead to a reflux of blood from the episcleral venous network into the anterior chamber in eyes with prior ab interno trabeculotomy. Glaucoma and retina specialists should be aware of this potential complication to guide follow up and management in the post-injection period for these patients.

RESUMEN

The aim of this case report is to present an unusual case of idiopathic thrombocytopenic purpura (ITP) with bilateral spontaneous hyphema. It refers to an 82-year-old Caucasian woman who presented with acute unilateral vision loss. The patient's medical history includes arterial hypertension, hypothyroidism, and uneventful bilateral cataract surgery. Bilateral anterior chamber hyphema was noted on gonioscopy, along with unilateral corneal edema. Hematology workup set the diagnosis of ITP. The cause of spontaneous bleeding in ITP patients is explained by the "second hit" hypothesis, suggesting that a secondary factor such as high blood pressure or minor trauma is necessary to cause rupture to a vessel's wall, which is already affected by the low platelet counts. The authors propose that, in this patient, the "second hit" was likely due to basement membrane alterations caused by arterial hypertension. The rarity of bilateral spontaneous hyphema cases and possible etiologies are emphasized.

RESUMEN

Introducción: El síndrome de uveítis-glaucoma-hifema (UGH) es una complicación infrecuente de las cirugías de catarata, debido a un roce mecánico ejercido por una lente intraocular (LIO) sobre el iris. Caso clínico: Un varón de 64 años, con antecedente de cirugía de catarata, presenta disminución de la agudeza visual y dolor en el ojo derecho. En el examen oftalmológico, se evidenciaron signos de uveítis anterior, presión intraocular (PIO) elevada, microhifema y una LIO de una pieza plegable en sulcus que provocaba un roce mecánico con la cara posterior del iris. El tratamiento médico fue insuficiente, por lo que se realizó una cirugía de explante de LIO de una pieza plegable y se reemplazó por una LIO de tres piezas plegables. La evolución posoperatoria fue favorable. Conclusión: Se debe sospechar de esta complicación, en pacientes con antecedente de cirugía de catarata, especialmente en casos en los cuales la LIO es de una pieza y ha sido implantada fuera del saco capsular.

Introduction: Uveitis-glaucoma-hyphema syndrome (UGH) is a rare complication of cataract surgery, due to mechanical chafing exerted by an intraocular lens (IOL) on the iris. Clinical case: A 64-year-old man with a history of cataract surgery, who presented decreased visual acuity and pain in the right eye. The ophthalmological examination revealed signs of anterior uveitis, elevated intraocular pressure (IOP), microhyphema, and a single-piece foldable IOL in the sulcus that caused a mechanical chafing with the posterior face of the iris. The medical treatment was insufficient; for this reason, a folding simple-piece IOL explant surgery was performed and replaced by a three-piece IOL. Postoperative evolution was favorable. Conclusion: Should be suspected this complication in patients with a history of cataract surgery, especially in cases in which the IOL is in single-piece and has been implanted outside the capsular bag.

RESUMEN

BACKGROUND: To evaluate retinal and choroidal vascular changes in cases with hyphema after blunt ocular trauma that did not cause globe rupture or any retinal pathology. METHODS: This cross-sectional study included 29 patients who developed hyphema after unilateral blunt ocular trauma (BOT). The other healthy eyes of the same patients were evaluated as the control group. Optical coherence tomography-angiography (OCT-A) was used for imaging. In addition, choroidal parameters were compared by calculating the choroidal vascular index (CVI) and using choroidal thickness measurements by two independent researchers. RESULTS: Superior and deep flow values were significantly decreased in the traumatic hyphema group compared to the control group (p<0.05). Parafoveal deep vascular density (parafoveal dVD) values were decreased in traumatized eyes compared to control eyes (p=0.000). Vascular density values were similar other than that. In addition, there was a significant decrease in optic disc blood flow (ODF) and optic nerve head density (ONHD) values compared to the control group (p<0.05). In addition, no significant difference was observed between the groups in terms of mean CVI values (p>0.05). CONCLUSION: Non-invasive diagnostic tools such as OCTA and EDI-OCT can be used to detect and monitor early changes in retinal and choroidal microvascular flow in cases of traumatic hyphema.
