Bilateral perifoveal macular ischemia in non-proliferative Duchenne muscular dystrophy-associated retinopathy: a case report.

Anterior segment examination revealed bilateral posterior subcapsular cataracts, while dilated fundoscopic examination was unremarkable.

Multifocal electroretinography demonstrated reduced amplitudes in the central and parafoveal rings, indicating localized retinal dysfunction.

Optical coherence tomography angiography disclosed bilateral, irregular enlargement of the foveal avascular zone consistent with perifoveal ischemia.

These vascular abnormalities corresponded to the areas of inner retinal thinning with secondary outer nuclear layer expansion in structural optical coherence tomography.
