Cystoid macular edema in gyrate atrophy of the choroid and retina: a fluorescein angiography and optical coherence tomography evaluation.

Abstract

To analyze the importance f optical coherence tomography (OCT) to diagnose the cystoid macular edema in a case of gyrate atrophy. Observational case report. A 12-year-old boy presenting with gyrate atrophy of the choroid and retina underwent ophthalmologic, clinical, and laboratory tests. Plasma ornithine level was 735 mumol/l. Fluorescein angiography showed bilateral hyperfluorescence involving the central region of the macula. Optical coherence tomography (OCT) disclosed bilateral intraretinal cysts areas of low reflectivity with occasional high-signal elements bridging the retinal layers and intraretinal thickening. Both fluorescein angiography and OCT were helpful to confirm the diagnosis of macular involvement as a complication of gyrate atrophy of the choroid and retina in a patient who presented without any clinical evidence of cystoid macular edema, except a decrease in visual acuity.
