PURPOSE Bietti crystalline dystrophy (BCD) is an autosomal recessive disease characterized by intraretinal deposits of multiple small crystals, with or without associated crystal deposits in the cornea. The disease is caused by mutation in the cytochrome p450, family 4, subfamily v, polypeptide 2 (CYP4V2) gene. Choroidal neovascularization (CNV) is a rare(More)
We report a rare case of Bietti's crystalline dystrophy presenting with choroidal neovascular membrane (CNVM) which was treated with three injections of intravitreal ranibizumab. The CNVM underwent scarring after the injections with stabilization of visual acuity at a follow-up period of 12 months suggesting that intravitreal ranibizumab may have a role in(More)
Optical coherence tomography (OCT) is now an integral part of management for numerous retinal diseases for diagnosis, treatment planning and follow up. OCT interpretation must involve the understanding of the associated artifacts. These artifacts can mislead physicians to wrong diagnosis or inappropriate management. This review article discusses the various(More)
BACKGROUND AND OBJECTIVE To report the outcome of treating circumscribed choroidal hemangioma (CCH) using transpupillary thermotherapy (TTT). PATIENTS AND METHODS An infrared diode laser was used at 810 nm with a median spot size of 2.5 mm, power of 550 mW, and duration of 6.5 minutes; the median number of sittings was two. TTT spared the center of the(More)
PURPOSE To find the abnormalities in various retinal layers caused by radiation retinopathy using spectral domain optical coherence tomography (SD-OCT). METHODS We report a case of radiation retinopathy that was imaged using SD-OCT Copernicus (Optopol, Zawiercie, Poland). Analysis and synthesis of the OCT image were done using information both at the(More)
OBJECTIVE To report the prevalence of myopia and its association with diabetic retinopathy in subjects with type II diabetes mellitus and compare the diabetic retinopathy status in the myopic group vs the emmetropic group. DESIGN Population-based study. MATERIALS AND METHODS The population-based study estimated the prevalence of myopia from 1058(More)
We conducted a retrospective review of 11 eyes undergoing eye wall resection between October 1998 and October 2009. The median age of 11 patients was 29 years. Decreased vision (eight) was the most common presenting symptom. Ciliary body medulloepithelioma was the most common clinical diagnosis (six). Medulloepithelioma was the most common histopathological(More)
