Pits of Fire: Post Scleral Graft Vasculitis in Patients With Optic Disc Pit Maculopathy.

Occlusive vasculitis is a rare complication following an uneventful surgery. In this article, we report two cases of optic disc pit maculopathy that underwent scleral graft and developed vasculitis following uneventful surgery. Both patients underwent autologous scleral graft for optic disc pit maculopathy through 25-gauge pars plana vitrectomy. Scleral graft was harvested from patient's same eye and plugged in the optic disc pit. After a postoperative period of approximately 3 months, both patients developed features of occlusive vasculitis with vitreous base contraction. Uveitic workup did not reveal other causes of vasculitis. Both patients were treated with topical and systemic steroids and responded well until the last follow-up.

Cluster of Post-Operative Endophthalmitis Caused by Acanthamoeba T10 Genotype - A First Report.

PURPOSE: To report a cluster of postoperative Acanthamoeba endophthalmitis after routine cataract surgeries. METHODS: A brief summary of sentinel events leading to the referral of 4 patients of postoperative endophthalmitis to our hospital is followed by clinical descriptions and the various diagnostic approaches and interventions used. Genotyping and phylogenetic analysis are also discussed. RESULTS: Four cases of postoperative cluster endophthalmitis, presumed to be bacterial and treated as such, were referred to our hospital. The presence of an atypical ring infiltrate in the first case facilitated the diagnosis of Acanthamoeba endophthalmitis. All patients had vitritis, corneal involvement, and scleral inflammation. Multiple diagnostic methods, such as corneal scrapings, confocal microscopy, aqueous and vitreous taps, scleral abscess drainage, histopathological studies, polymerase chain reaction, and genotyping and phylogenetic analyses of isolated Acanthamoeba, were used to confirm the diagnosis of endophthalmitis and to establish the extent of ocular involvement. Various medical and therapeutic interventions used to control the infections were also documented. The isolated Acanthamoeba were confirmed as belonging to the T10 genotype, an environmentally and clinically rare variety. CONCLUSIONS: This is the first report of a cluster of postoperative T10 genotype Acanthamoeba endophthalmitis, occurring after routine cataract surgery in immunocompetent individuals. Contrary to current perceptions, a rapidly evolving infection can occur with Acanthamoeba.

Spontaneous anatomical and functional recovery of bilateral electric shock maculopathy.

A 12-year-old boy presented with best-corrected visual acuity (BCVA) of 6/9 in both eyes following an episode of electric shock. Optical coherence tomography (OCT) showed disruption of the ellipsoid zone as well as retinal pigment epithelium (RPE) layer. Fundus autofluorescence (FAF) showed increased central hypoautofluorescence in both eyes. At 3-month follow-up, BCVA improved to 6/6 with OCT showing spontaneous resolution of maculopathy in both eyes with reorganized RPE layer and ellipsoid zone. To the best of our knowledge, this is the first case of bilateral electric shock maculopathy (ESM) with spontaneous anatomical as well as functional recovery. Ophthalmologists must be aware of various forms of ESM. OCT and FAF must be done in patients presenting with defective vision and history of electric shock for the diagnostic as well as prognostic evaluation.
