RESUMO

A 29-year-old female presented to the emergency clinic with gradual visual disturbance in both eyes for 15 days duration, accompanied by bilateral tinnitus, and ocular pain that increased with ocular movements. One month prior to presentation, the patient had tested positive for severe acute respiratory syndrome coronavirus-2 but without complications. Visual acuity was 20/100 in the right eye and 20/300 in the left eye. Funduscopy demonstrated optic nerve swelling, radial nerve fiber striation disruption, and bilateral retinal folds. Optical coherence tomography showed serous (bacillary) retinal detachment and multifocal areas of hyper-reflective changes in the inner and outer plexiform layer with inner nuclear layer thickening and disruption of the interdigitation zone bilaterally. We present a case of incomplete Vogt-Koyanagi-Harada disease following COVID-19 infection.

RESUMO

A 56-year-old female presented with vitreous opacity with gradual visual disturbance in her right eye of 1-year duration. A Non-Hodgkin's lymphoma had been treated 15 years before. Presenting best-corrected visual acuity (BCVA) was 20/200 in her right eye and 20/25 in her left eye. Intraocular pressure was 18 mm Hg bilaterally. Slit-lamp examination revealed no abnormal findings in the anterior segment of both eyes, including the absence of cells and flare. Fundoscopic examination indicated hazy media with the typical glass-wool-like appearance in her right eye. B-scan ultrasound demonstrated that the vitreous was full of middle-echo spots, vitreous opacities, and posterior vitreous detachment occurred. The patient underwent vitreous biopsy and a standard 25-gauge pars plana vitrectomy (diagnostic and therapeutic). Intraoperatively, the eye was noted to have severe diffuse debris and very strong vitreoretinal adhesions. Cytospin smears prepared from the vitreous aspirate indicated amorphous acellular material that stained positively with Congo Red and showed apple green birefringence on polarized microscopy, consistent with the diagnosis of amyloidosis. A genetic evaluation of tongue tissue demonstrated apolipoprotein AI-derived amyloidosis. The BCVA was 20/25 OU at 3 months postoperatively.

RESUMO

PURPOSE: To introduce a modified technique for encircling circumferential scleral buckling without peritomy thorough a small conjunctival opening for the repair of uncomplicated rhegmatogenous retinal detachment (RD). METHODS: This technique was performed in 10 eyes of 10 patients with primary rhegmatogenous RD who underwent encircling circumferential scleral buckling without peritomy. Transconjunctival traction sutures were placed in four rectus muscles. After transconjunctival location of the retinal break, a 5- to 6-mm radial conjunctival incision was performed in 4 quadrants without cutting the limbal conjunctiva-Tenon's capsule. A 240-silicone band in scleral belt loops was used for an encircling circumferential buckle. After drainage and cryopexy, SF6 was used for tamponade. The incision was closed via layered closure only ocassionally. RESULTS: Primary attachment success of 100% was achieved by single procedure. The intraoperative and postoperative complications observed included subconjunctival hemorrhage observed in 5 (50%) of eyes. These disappeared in the postoperative period. CONCLUSIONS: Minimal conjunctival incision in scleral buckle without peritomy can achieve excellent anatomical success in patients with rhegmatogenous RD without distorting ocular surface anatomy. This is the first description of technique preserving corneal limbus anatomy that could convert buckling surgery to more attractive option for retina surgeons.

RESUMO

PURPOSE: To report the use of anterior lens capsule flap transplantation in two cases with chronic full-thickness macular hole (MH). METHODS: Case series. RESULTS: Two cases of chronic MH with a new treatment approach were reported. In the first case, a 66-year-old man presented with a chronic idiopathic MH in the left eye for 2 years. Presenting visual acuity was hand motion. The patient underwent phacoemulsification and vitrectomy with anterior lens capsule flap transplantation in the MH. At 5 months postoperatively, the visual acuity was 20/200 with MH closure. In the second case, a 68-year-old woman presented with decreased visual acuity for 2 years. Her visual acuity was hand motion in the right eye. The patient underwent phacoemulsification and vitrectomy with anterior lens capsule flap transplantation in the MH. Visual acuity improved to 20/400 with reduction in the MH diameter. Vision and MH diameter remained stable over 5 months postoperatively. CONCLUSION: Lens capsular flap transplantation is useful in closing chronic MH in the short term.

RESUMO

Importance: The ocular manifestations and sequelae of Zika virus infection are not well known. Recently, the World Health Organization changed the declaration of Zika as a public health emergency and designated the viral outbreak and related microcephaly clusters as a long-term program of work. This change indicates the urgent need to evaluate and document ophthalmic manifestations in patients for timely management of this disease. In addition, confirmation whether the public health problem in Brazil extends to other regions in South America is needed. Objective: To report the ocular manifestations of congenital Zika syndrome with microcephaly in Colombia and Venezuela. Design, Setting, and Participants: This prospective case series included 43 patients from 2 ophthalmic centers in Colombia and Venezuela who underwent evaluation from October 1, 2015, through June 30, 2016, and were clinically diagnosed with congenital Zika syndrome. Twenty patients were Hispanic; 13, African; 8, white; and 2, Native American. Interventions: Ophthalmic and systemic evaluations and serologic testing were performed on all infants. Patients underwent external ocular examination and dilated ophthalmoscopy. Serologic testing ruled out toxoplasmosis, rubella, cytomegalovirus, syphilis, and human immunodeficiency virus. Main Outcomes and Measures: Ophthalmic manifestations of congenital Zika syndrome. Results: Of the 43 patients included in this series (28 female and 15 male), the mean (SD) age at examination was 2.1 (1.5) months. The mothers of all the children had no ophthalmic findings and did not report ocular symptoms during pregnancy. All patients had bilateral ophthalmic manifestations. Optic nerve findings included hypoplasia with the double-ring sign, pallor, and increased cup-disc ratio in 5 patients (11.6%). Macular abnormalities included mild to severe pigment mottling in 27 patients (63%) and lacunar maculopathy in 3 (6.9%). Chorioretinal scarring was present in 3 patients (7%). Eleven patients (26%) had a combination of lesions in the posterior pole. Five patients (12%) were diagnosed with congenital glaucoma, characterized by the clinical triad of epiphora, photophobia, and blepharospasm; increased intraocular pressure; corneal clouding at birth; and buphthalmos. These data reveal that 12% (95% CI, 5%-24%) of cases of congenital Zika with microcephaly had anterior segment abnormalities and 88% (95% CI, 76%-94%) had important macular and optic nerve abnormalities. The visual sequelae of these ophthalmic manifestations remain unknown. Conclusions and Relevance: Congenital Zika syndrome in the current study had severe ocular abnormalities, and all patients had bilateral involvement. Ocular findings were focal macular pigment mottling, chorioretinal atrophy with a predilection for the macular area, congenital glaucoma and optical nerve hypoplasia, and optic disc abnormalities. Ophthalmic examination is recommended in patients with congenital Zika syndrome.

RESUMO

We describe a new surgical technique, intraoperative peripheral anterior capsulotomy (IPAC), to prevent early postoperative capsular block syndrome (CBS). Eighty consecutive patients (80 eyes) had phacoemulsification and intraocular lens implantation with IPAC in the presence of a small (4.5 to 5.0 mm) anterior continuous curvilinear capsulorhexis (CCC). Patients were followed for a mean of 16 months (range 6 to 24 months), and none developed CBS or other complications. Our series suggests that IPAC may be an alternative to prevent CBS in high-risk eyes, including those with a small anterior CCC or ophthalmic viscosurgical device material trapped in the capsular bag. This surgical technique is safe, effective, inexpensive, and easy to perform.
