RESUMEN

Various strategies for replacing retinal neurons lost in degenerative diseases are under investigation, including stimulating the endogenous regenerative capacity of Müller Glia (MG) as injury-inducible retinal stem cells. Inherently regenerative species, such as zebrafish, have provided key insights into mechanisms regulating MG dedifferentiation to a stem-like state and the proliferation of MG and MG-derived progenitor cells (MGPCs). Interestingly, promoting MG/MGPC proliferation is not sufficient for regeneration, yet mechanistic studies are often focused on this measure. To fully account for the regenerative process, and facilitate screens for factors regulating cell regeneration, an assay for quantifying cell replacement is required. Accordingly, we adapted an automated reporter-assisted phenotypic screening platform to quantify the pace of cellular regeneration kinetics following selective cell ablation in larval zebrafish. Here, we detail a method for using this approach to identify chemicals and genes that control the rate of retinal cell regeneration following selective retinal cell ablation.

RESUMEN

ABSTRACT Purpose: To characterize the extracellular vesicle protein cargo in the aqueous humor and plasma of patients with ocular toxoplasmosis. Methods: Aqueous humor and plasma were collected from six patients with active ocular toxoplasmosis and six patients with cataract. Extracellular vesicles were isolated, and western blotting and mass spectrometry were performed for protein analysis. Results: All plasma samples from patients with ocular toxoplasmosis and cataract were positive for the tetraspanins CD63 and TSG101. However, the aqueous humor from patients with ocular toxoplasmosis was positive only for CD63. Sixty-seven new unreported proteins were identified in the aqueous humor and plasma of patients with the ocular toxoplasmosis and cataract. Of the 67 proteins, 10 and 7 were found only in the cataract and ocular toxoplasmosis groups, respectively. In general, these proteins were involved in immune system activation and retina homeostasis and were related to infections and retina-associated diseases. Conclusion: The distinct protein signatures between ocular toxoplasmosis and cataract may be helpful in the differential diagnosis of ocular toxoplasmosis. However, more studies are needed to better understand the role of these proteins in the pathogenesis of ocular toxoplasmosis.

RESUMEN

OBJECTIVE: To determine whether novel pre- and postsurgical ultrasound biomicroscopy (UBM) measurements of the canine ciliary cleft (CC) are associated with postoperative ocular hypertension (POH) following cataract surgery and to explore the relationship between intraocular pressure and CC UBM measurements. METHODS: Following pharmacologic mydriasis, UBM images were obtained from 31 client-owned dogs before elective cataract surgery, immediately postsurgery, and 4 to 6 hours following surgery or while experiencing POH ≥ 25 mm Hg. Presurgery and the pre- to postsurgery change in CC measurements were assessed for association with POH using individual mixed-effects logistic regression models and forward variable selection models. Linear mixed-effects models were used to evaluate the relationship of intraocular pressure to UBM measurements within the same eye across multiple time points. RESULTS: Presurgical measurements were not predictive of POH development. An increase in pectinate ligament distance and CC area from presurgical baseline to immediate postsurgical measurement was associated with reduced odds of developing POH, while increasing CC length (from apex to mid point on the pectinate ligament) from pre- to postsurgery and immature cataracts was associated with increased odds of POH. CONCLUSIONs: The change in CC morphology following cataract surgery appears more impactful in the development of POH than individual variations in presurgery CC measurements. Several changes in the CC dimensions following surgery appear associated with POH risk. CLINICAL RELEVANCE: This understanding of a potential mechanism of POH development opens new avenues for researching preventative measures associated with modifying surgical techniques to influence CC morphology following cataract surgery.

RESUMEN

BACKGROUND: Human amniotic membrane (AM) transplantation has been applied to treat ocular surface diseases, including corneal trauma. The focus of much deliberation is to balance the mechanical strength of the amniotic membrane, its resistance to biodegradation, and its therapeutic efficacy. It is commonly observed that the crosslinked human decellularized amniotic membranes lose the functional human amniotic epithelial cells (hAECs), which play a key role in curing the injured tissues. METHODS AND RESULTS: In this study, we crosslinked human decellularized amniotic membranes (dAM) with genipin and re-planted the hAECs onto the genipin crosslinked AM. The properties of the AM were evaluated based on optical clarity, biodegradation, cytotoxicity, and ultrastructure. The crosslinked AM maintained its transparency. The color of crosslinked AM deepened with increasing concentrations of genipin. And the extracts from low concentrations of genipin crosslinked AM had no toxic effect on human corneal epithelial cells (HCECs), while high concentrations of genipin exhibited cytotoxicity. The microscopic observation and H&E staining revealed that 2 mg/mL genipin-crosslinked dAM (2 mg/mL cl-dAM) was more favorable for the attachment, migration, and proliferation of hAECs. Moreover, the results of the CCK-8 assay and the transwell assay further indicated that the living hAECs' tissue-engineered amniotic membranes could facilitate the proliferation and migration of human corneal stromal cells (HCSCs) in vitro. CONCLUSIONS: In conclusion, the cl-dAM with living hAECs demonstrates superior biostability and holds significant promise as a material for ocular surface tissue repair in clinical applications.

RESUMEN

BACKGROUND: The pathogenesis of intermittent exotropia (IXT) remains unclear. The study aims to investigate alterations of resting-state networks (RSNs) in IXT adult patients using resting-state functional magnetic resonance imaging (rs-fMRI) data to explore the potential neural mechanisms. METHODS: Twenty-six IXT adult patients and 22 age-, sex-, handedness-, and education-matched healthy controls (HCs) underwent fMRI scanning and ophthalmological examinations. Brain areas with significant functional connectivity (FC) differences between the IXT and HC groups were selected as regions of interest (ROI) and mean z-scores were calculated to control for individual differences. RESULTS: Compared with HCs, IXT patients exhibited altered FC in various brain regions within RSNs involved in binocular fusion, stereopsis, ocular movement, emotional processes and social cognition, including the default mode network (DMN), the dorsal attention network (DAN), the visual network (VN), the sensorimotor network (SMN), the executive control network (ECN), the frontoparietal network (FPN) and the auditory network (AN). The degree of exodeviation was positively correlated with FC value of left middle occipital gyrus (MOG) within the VN. Correspondingly, we found a negative correlation between the degree of exodeviation and the FC value of left angular gyrus (AG) within FPN (P < 0.05). The FNC analysis between different RSNs also provides evidence on visual-motor cortical plasticity. CONCLUSIONS: IXT patients showed widespread changes of brain activity within RSNs related to binocular fusion, stereopsis, oculomotor control, emotional processes, and social cognition. These findings extend our current understanding of the neuropathological mechanisms of IXT. TRIAL REGISTRATION: Beginning date of the trial: 2021-09-01.

RESUMEN

Ocular metastasis (OM) in breast cancer (BC) always predicts poor prognosis. The present study explored differences in tumor markers in patients with BC with and without OM, and attempted to determine risk factors for OM in patients with BC. This study involved 629 patients with BC. Patients' clinical features were tested using χ2 test, unpaired Student's t-test and Mann-Whitney U. These parameters were analyzed using binary logistic regression to obtain risk factors for OM. A receiver operating characteristic curve was then established to determine the diagnostic value for OM. There were no significant differences in age, sex, menopausal state, and pathological type between the two groups. Significantly more axillary lymph node metastases were observed in the OM group compared with the non-ocular metastases group. Cancer antigen 153 (CA153) was revealed to be a significant independent risk factor for OM in patients with BC. The cutoff CA153 value for diagnosis of OM was 43.00 u/ml, the sensitivity was 96.15% and the specificity was 96.02%. In conclusion, CA153 was demonstrated to be a risk factor for OM in patients with BC. High levels of CA153 were associated with OM in patients with BC.

RESUMEN

The gut microbiome has been studied in recent years due to its association with various pathological pathways involved in different diseases, caused by its structure, function, and diversity alteration. The knowledge of this mechanism has generated interest in the investigation of its relationship with ophthalmologic diseases. Recent studies infer the existence of a gut-eye microbiota axis, influenced by the intestinal barrier, the blood-retina barrier, and the immune privilege of the eye. A common denominator among ophthalmologic diseases that have been related to this axis is inflammation, which is perpetuated by dysbiosis, causing an alteration of the intestinal barrier leading to increased permeability and, in turn, the release of components such as lipopolysaccharides (LPS), trimethylamine oxide (TMAO), and bacterial translocation. Some theories explain that depending on how the microbiome is composed, a different type of T cells will be activated, while others say that some bacteria can pre-activate T cells that mimic ocular structures and intestinal permeability that allow leakage of metabolites into the circulation. In addition, therapies such as probiotics, diet, and fecal microbiota transplantation (FMT) have been shown to favor the presence of a balanced population of microorganisms that limit inflammation and, in turn, generate a beneficial effect in these eye pathologies. This review aims to analyze how the intestinal microbiome influences various ocular pathologies based on microbial composition and pathological mechanisms, which may provide a better understanding of the diseases and their therapeutic potential.

RESUMEN

Purpose: To report a rare case of globe rupture with broken calcified senile scleral plaque (SSP). Observations: A 94-year-old male patient presented with left eye pain and severely decreased left vision immediately after the injury while farming. Examination of the left eye revealed edematous cornea, diffuse subconjunctival hemorrhage, total hyphema and iris prolapse. Preoperative computed tomography (CT) scan revealed calcified SSP in both eyes, and the calcified SSP was found to be broken during surgery. Although it was impossible to thread the broken calcified SSP, threading and suturing with long bites outside of the broken calcified SSP was effective for wound closure. Postoperatively, we were able to observe the broken calcified SSP and the wound closure using anterior segment optical coherence tomography (AS-OCT). Conclusions and importance: In a case of globe rupture with calcified SSP on preoperative CT, the possibility that the SSP has also ruptured should be considered. AS-OCT is also useful to observe the wound in a case of globe rupture with broken SSP during follow-up.

RESUMEN

Background: Data regarding ocular tuberculosis (OTB) in the United States have not been previously reported. We evaluated trends of OTB compared with other extrapulmonary TB (EPTB). Methods: We estimated the proportion of all EPTB cases (with or without concurrent pulmonary involvement) with OTB reported to the National Tuberculosis Surveillance System during 1993-2019. We compared demographics and clinical characteristics of people with OTB and other EPTB during 2010-2019. P values were calculated by chi-square test for categorical variables and Kruskal-Wallis for continuous variables. Results: During 1993-2019, 1766 OTB cases were reported, representing 1.6% of 109 834 all EPTB cases: 200 (0.5% of 37 167) during 1993-1999, 395 (1.0% of 41 715) during 2000-2009, and 1171 (3.8% of 30 952) during 2010-2019. In contrast to persons with other EPTB, persons with OTB were older (median, 48 vs 44 years; P < .01), more likely to be US-born (35% vs 28%; P < .01), more likely to have diabetes (17% vs 13%; P < .01), and less likely to have HIV (1% vs 8%; P < .01). OTB was less likely to be laboratory confirmed (5% vs 75%; P < .01), but patients were more likely to be tested by interferon gamma release assay (IGRA; 84% vs 56%; P < .01) and to be IGRA positive (96% vs 80%; P < .01). Conclusions: Reported OTB increased during 1993-2019 despite decreasing TB, including EPTB; the largest increase occurred during 2010-2019. OTB was rarely laboratory confirmed and was primarily diagnosed in conjunction with IGRA results. More research is needed to understand the epidemiology of OTB to inform clinical and diagnostic practices.

RESUMEN

Intraocular foreign bodies (IOFBs) remain a severe complication of ocular trauma commonly encountered worldwide. This literature review aimed to discuss current practice patterns, areas of controversy, and advances in the management of IOFBs. Injuries involving IOFBs carry significant ocular morbidity and management can be extremely challenging. A systematic approach to preoperative evaluation and IOFB surgical management is detailed in this article and should be applied in each case. The location and composition of an IOFB have important implications on surgical approach and timing, especially in cases of toxic metals and vegetable matter. The advantages, disadvantages, and previous literature regarding immediate versus delayed foreign body removal are presented. Surgical approaches are described, with an emphasis on posterior chamber IOFB management and removal via pars plana vitrectomy. Final visual acuity is variable, but approaches have been used to prognosticate outcomes including the Ocular Trauma Score. By synthesizing current IOFB literature, the goal is to provide practitioners with guidance that will maximize the chances of surgical success and patient outcomes.

RESUMEN

Purpose: To use artificial intelligence to identify relationships between morphological characteristics of the Meibomian glands (MGs), subject factors, clinical outcomes, and subjective symptoms of dry eye. Methods: A total of 562 infrared meibography images were collected from 363 subjects (170 contact lens wearers, 193 non-wearers). Subjects were 67.2 % female and were 54.8 % Caucasian. Subjects were 18 years of age or older. A deep learning model was trained to take meibography as input, segment the individual MG in the images, and learn their detailed morphological features. Morphological characteristics were then combined with clinical and symptom data in prediction models of MG function, tear film stability, ocular surface health, and subjective discomfort and dryness. The models were analyzed to identify the most heavily weighted features used by the algorithm for predictions. Results: MG morphological characteristics were heavily weighted predictors for eyelid notching and vascularization, MG expressate quality and quantity, tear film stability, corneal staining, and comfort and dryness ratings, with accuracies ranging from 65 % to 99 %. Number of visible MG, along with other clinical parameters, were able to predict MG dysfunction, aqueous deficiency and blepharitis with accuracies ranging from 74 % to 85 %. Conclusions: Machine learning-derived MG morphological characteristics were found to be important in predicting multiple signs, symptoms, and diagnoses related to MG dysfunction and dry eye. This deep learning method illustrates the rich clinical information that detailed morphological analysis of the MGs can provide, and shows promise in advancing our understanding of the role of MG morphology in ocular surface health.

RESUMEN

Connective tissue diseases (CTDs), including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjögren's syndrome, and systemic sclerosis (SSc), represent a diverse group of disorders characterized by abnormalities in the proteins that support tissues and organs. These diseases can affect multiple organ systems and are often associated with significant morbidity and mortality. The eyes are frequently affected among the various organ systems involved, with ocular manifestations ranging from benign conditions such as dry eye syndrome to severe, sight-threatening complications like scleritis, retinal vasculitis, and optic neuritis. Recognizing and managing these ophthalmologic implications is crucial for preventing severe complications, providing diagnostic clues, and improving patients' quality of life. This comprehensive review aims to elucidate the current knowledge and innovations related to the ophthalmologic implications of CTDs. It details the ocular manifestations associated with major CTDs, explores diagnostic approaches to identifying and differentiating these conditions, and discusses management strategies, including pharmacological and surgical interventions. Additionally, the review highlights recent advancements and emerging therapies in diagnosing and treating CTD-related ophthalmologic conditions. The review also addresses this field's challenges and future directions, emphasizing the importance of interdisciplinary collaboration and continuous research. By synthesizing the latest research and clinical insights, this review seeks to enhance the understanding of healthcare professionals regarding the interplay between CTDs and ocular health, ultimately contributing to improved patient care and outcomes.

RESUMEN

BACKGROUND: To review the characteristics of all Slovenian patients with ocular adnexal lymphoma (OAL) in the period of 24 years with the aim of evaluating demographic data, lymphoma location and type, disease stage, treatment modality, local control rate and survival rate. PATIENTS AND METHODS: All patients with histologically diagnosed OAL in the main tertiary centre of Slovenia, Eye Hospital, University Medical Centre Ljubljana, who were treated at Institute of Oncology Ljubljana were included in the study. Patients' data were collected from October 1995 through April 2019. RESULTS: Seventy-four patients were included in the study having a median age of 68 years at diagnosis. The majority of lymphomas were of B-cell origin (98.6%). The most frequent type was the extranodal marginal zone B-cell lymphoma (MALT) (71.6%). Orbital lymphomas were diagnosed in 56 cases (75.7%) and conjunctival in 18 cases (24.3%). Ocular manifestation was the first sign of the disease in 78.4% of patients and in 67.6% of patients ocular adnexa were the only disease location. Fifty-one patients (68.9%) were treated with radiotherapy, 7 patients (9.4%) with systemic treatment, 5 patients (6.8%) with combined radiotherapy and systemic treatment and in 11 patients, biopsy and active surveillance strategy was applied (14.9%). Local control of the disease was achieved in 96.6% of treated patients. Median overall survival of the whole study group has not been reached yet. Five-year overall survival rate was 80.1% (95% CI 68.1% - 88.5%) and 5-year lymphoma specific survival rate was 87.2% (95% CI 83.2%-91.2%). CONCLUSIONS: OALs comprise a group of heterogeneous diseases with variable outcomes depending predominately on the patient's age and lymphoma type, with low grade lymphomas carrying good prognosis even in elderly patients.

RESUMEN

Glaucoma presents a significant global health concern and affects millions of individuals worldwide and predicted a high increase in prevalence of about 111 million by 2040. The current standard treatment involves hypotensive eye drops; however, challenges such as patient adherence and limited drug bioavailability hinder the treatment effectiveness. Nanopharmaceuticals or nanomedicines offer promising solutions to overcome these obstacles. In this manuscript, we summarized the current limitations of conventional antiglaucoma treatment, role of nanomedicine in glaucoma treatment, rational design, factors effecting the performance of nanomedicine and different types of nanocarriers in designing of nanomedicine along with their applications in glaucoma treatment from recent literature. Current clinical challenges that hinder real-time application of antiglaucoma nanomedicine are highlighted. Lastly, future directions are identified for improving the therapeutic potential and translation of antiglaucoma nanomedicine into clinic.

RESUMEN

AIM: To analyze the spectrum of isolated pathogens and antibiotic resistance for ocular infections within 5y at two tertiary hospitals in east China. METHODS: Ocular specimen data were collected from January 2019 to October 2023. The pathogen spectrum and positive culture rate for different infection location, such as keratitis, endophthalmitis, and periocular infections, along with antibiotic resistance were analyzed. RESULTS: We included 2727 specimens, including 827 (30.33%) positive cultures. A total of 871 strains were isolated, 530 (60.85%) bacterial and 341 (39.15%) fungal strains were isolated. Gram-positive cocci (GPC) were the most common ocular pathogens. The most common bacterial isolates were Staphylococcus epidermidis (25.03%), Staphylococcus aureus (7.46%), Streptococcus pneumoniae (4.59%), Corynebacterium macginleyi (3.44%), and Pseudomonas aeruginosa (3.33%). The most common fungal genera were Fusarium spp. (12.74%), Aspergillus spp. (6.54%), and Scedosporium spp. (5.74%). Staphylococcus epidermidis strains showed more than 50% resistance to fluoroquinolones. Streptococcus pneumoniae and Corynebacterium macginleyi showed more than 90% resistance to erythromycin. The percentage of bacteria showing multidrug resistance (MDR) significantly decreased (χ 2=17.44, P=0.002). CONCLUSION: GPC are the most common ocular pathogens. Corynebacterium macginleyi, as the fourth common bacterium, may currently be the local microbiological feature of east China. Fusarium spp. is the most common fungus. More than 50% of the GPC are resistant to fluoroquinolones, penicillins, and macrolides. However, the proportion of MDR strains has been reduced over time.

RESUMEN

AIM: To investigate the effect of adding autologous serum eye drops to the postoperative regime after amniotic membrane transplantation for severe persistent corneal ulcers. METHODS: Forty eyes of 40 patients with persistent corneal ulcers were randomly assigned to artificial tears (sodium hyaluronate 0.2%, ATs group, n=20) or autologous serum eye drops (ASEDs, n=20) following treatment with amniotic membrane transplantation. Digital slit lamp images were acquired from all patients before and 30d post treatment. The area with fibrovascular tissue was calculated using Image J. Central corneal sensitivity was assessed by Cochet-Bonnet aesthesiometry before and one month after treatment. Scar tissue transparency was assessed with a novel optical densitometry. RESULTS: Mean age of patients was 61.65±16.47y and 57.3±19.11y in the ATs group and ASEDs group, respectively. Twenty-two male and 18 female patients were included in the study. The improvement in visual acuity was significantly greater in the ASEDs group (0.14±0.04) than the ATs (0.08±0.04; P=0.00046). Cochet-Bonnet aesthesiometry improved significantly after treatment with a similar rate between groups. There were no statistically significant differences in the area of postoperative fibrovascular tissue between the two groups (P=0.082). The success rate in the two groups was similar. The difference in densitometry between the ATs and ASEDs group was statistically significant (P=0.042) with greater reduction from baseline in the ASEDS group. CONCLUSION: Autologous serum eye drops can lead to better visual acuity, more stable results and improved densitometry and should be considered in the postoperative care following amniotic membrane transplantation.

RESUMEN

Ophthalmology is a subject that highly depends on imaging examination. Artificial intelligence (AI) technology has great potential in medical imaging analysis, including image diagnosis, classification, grading, guiding treatment and evaluating prognosis. The combination of the two can realize mass screening of grass-roots eye health, making it possible to seek medical treatment in the mode of "first treatment at the grass-roots level, two-way referral, emergency and slow treatment, and linkage between the upper and lower levels". On the basis of summarizing the AI technology carried out by scholars and their teams all over the world in the field of ophthalmology, quite a lot of studies have confirmed that machine learning can assist in diagnosis, grading, providing optimal treatment plans and evaluating prognosis in corneal and conjunctival diseases, ametropia, lens diseases, glaucoma, iris diseases, etc. This paper systematically shows the application and progress of AI technology in common anterior segment ocular diseases, the current limitations, and prospects for the future.

RESUMEN

Even though a non-negligible portion of congenital eye anomalies has a clear genetic origin, an etiology is not found for most patients. Prenatal medication exposure is recognized to be involved in fetal malformations and several medications are specifically known to alter eye morphogenesis during embryonic development leading to congenital eye defects. We explored and reviewed the role of medications described in the genesis of ocular malformations, a role that has been little evaluated and probably still underestimated especially since several studies have shown the wide exposure of pregnant women to medication. We present our results in two sections; the first describes medications reported to be associated with ocular malformations in humans; the second details medications responsible for ocular malformations in animal models. We have summarized these results in tables, providing a relevant tool for clinicians. As most of the associations between medication exposure and congenital eye defects are either old or single case reports, this study highlights the needs for high epidemiological vigilance, accurate clinical description as well as a combination of studies on human genetics and experimental studies. Since medication exposures are potentially modifiable risk factors for congenital anomalies, this represents an important opportunity to implement preventive measures.
