Abstract
This photo essay describes the optical coherence tomography (OCT) characteristics seen in gyrate atrophy (GA). A 39-year-old female presented with decreased night vision and peripheral vision, best-corrected visual acuity of 20/60 N10 and 20/40 N8 in both eyes, respectively. Fundus examination showed large confluent areas of chorioretinal atrophy involving the disc and leaving an annular zone of the normal retina at the macula. OCT of the macula of the right eye showed hyporeflective cystic spaces in the inner retina and epiretinal membrane, and the left eye was normal while that through the GA showed loss of reflectivity from the nerve fiber layer, extensive loss of inner segment/outer segment layer, thinning of inner retinal layers, retinal pigment epithelium, and Bruchs membrane (BM) and increased visibility of large choroidal-like vessels which appear to be in close proximity to the interpreted BM.
