Ocular Gnathostomiasis Presenting as Branch Retinal Artery Occlusion.

PURPOSE: To report a case of ocular Gnathostomiasis presenting as branch retinal artery occlusion. METHOD: Observational case report. RESULT: A 22-year-old Asian woman presented to her ophthalmologist with redness, tearing, and decreased vision in her left eye. Examination revealed anterior uveitis and branch retinal artery occlusion associated with both intra-retinal and vitreous hemorrhage. The patient was treated with topical corticosteroids and cycloplegics. After 3 weeks, she presented in our emergency, with further decrease in vision and worsening pain in the left eye. Slit lamp examination revealed a brown colored live worm on the posterior corneal surface, anterior uveitis, multiple iris holes, and vitreous cells. Indirect ophthalmoscopy showed focal retinal hemorrhages, subretinal tracts, and vitreous hemorrhage. Surgical removal of the worm from anterior chamber was done immediately. CONCLUSION: Branched retinal artery occlusion with intraretinal and vitreous hemorrhage, panuveitis, and multiple iris holes may suggest the presence of an intraocular parasite.

Comparison of encirclage and cryotherapy with argon laser in the management of traumatic cyclodialysis cleft.

The study compared anatomical and functional outcome of a novel technique of encirclage and cryotherapy with the conventional argon laser in the management of traumatic cyclodialysis cleft in 19 patients (10: encirclage and 9: argon laser). The postoperative anatomical success was taken as rise in intraocular pressure (IOP) more than 6 mm Hg or the closure of cleft on gonioscopy or ultrasound biomicroscopy (UBM). Visual outcome was measured as change in logMAR visual acuity. Traumatic cataract and hypotony were present in majority. IOP>6 mm Hg was noted in 90% of encirclage group and in 77.70% of argon laser group. Two cases had non-closure of cleft. Encirclage is comparable to argon laser in terms of anatomical and functional success with possible advantage of single procedure and use in cases with failed laser.
