Atypical Presentation and Delayed Diagnosis of Gyrate Atrophy: Case Reports of Two Siblings.

Gyrate atrophy (GA) is a hereditary condition characterized by ornithine aminotransferase deficiency-related large areas of retinal pigment epithelium and choriocapillaris lobular-shaped atrophy in the peripheral retina. In this report, we present a case of atypical presentation of GA. The aim of this report is to present two siblings, one of which was associated with a lamellar macular hole and with a history of previous diagnosis of retinitis pigmentosa. The delayed diagnosis of GA was made only after her brother, who was 5 years younger than her was diagnosed with GA. In addition, in this report, we evaluated GA in terms of multimodal imaging findings, differential diagnosis, and treatment of macular complications.
