A case with bilateral C-shaped autofluorescence in retinal degeneration

This report highlights a novel retinal feature-a double C-shaped autofluorescent ring-associated with OPA13, potentially serving as a diagnostic marker for the disease. The findings emphasize the role of genetic testing in diagnosing OPA13 and distinguishing it from other retinal and optic neuropathies. Recognition of this feature could enhance early diagnosis and management strategies for patients with suspected OPA13.
