Abstract

We are presenting a case of a 55-year-old male, referred from Psychiatry Department for Alcohol Withdrawal Syndrome, with complaints of progressive diminution of vision in both eyes and defective night vision.

On ocular examination, his BCVA was 6/12 in the right eye and 6/18 in left eye, N12 in both eyes. His Color vision was impaired. His anterior segment was unremarkable with fundus evaluation showing white, refractive, crystalline deposits in the deeper retinal layer restricted to the parafoveal region, associated with RPE degeneration. On SD-OCT, hyper-reflective dots were seen in intra-retinal layers, corresponding to the crystalline deposits observed on fundus examination, along with intra-retinal tubulations. 24-2 Humphrey’s Visual field showed paracentral scotomas bilaterally with ERG showing subnormal results. We made a provisional diagnosis of Bilateral early Bietti’s Crystalline Dystrophy. This is an interesting case due to its rarity. Details of the same will be presented.
