CASE REPORTMultimodal Imaging of Gyrate Atrophy Associated With Foveoschisis, Epiretinal Membrane and Optic Nerve Head Drusen: A Case Report

Özet

We reporta young male patient with gyrate atrophy (GA) complicated by foveoschisis, epiretinal membrane and optic nerve head dusen (ONHD) using multimodal imaging. A 25-year-old man presented with a history of progressive night blindness and visual impairment over six years. He had undergone cataract operation for both eyes in another hospital three months previously. He had a history of high myopia. His best corrected visual acuity (BCVA) was 6/20 on Snellen chart in both eyes. Anterior segment examination showed presence of bilateral intraocular lens. Dilated fundus examination revealed bilateral sharply-defi ned and confl uent chorioretinal atrophic areas in the mid-peripheral zone. Large optic disc and temporal crescent were compatible with high myopia. The patient underwent imaging with colour fundus photography, fundus autofl uorescence (FAF), fundus fl uorescein angiography (FFA), optical coherence tomography (OCT). After all these evaluations, GA associated with foveoschisis, epiretinal membrane and ONHD were detected. Elevated levels of plasma ornithine were also detected (520 micromol/L) to confi rm diagnosis. Because of possible complications, biomicroscopic examination with the multimodal imaging must be done carefully to detect the problems associated with gyrate atrophy.
