Abstract Details



Purpose:

To evaluate a patient with visual deterioration and nyctalopia and to emphasize the importance of imaging in diagnosis.

Setting:

Case presentation and imaging

Methods:

A 38 year old woman without any known systemic or ocular disease presented with progressive visual deterioration and nyctalopia. Her best corrected visual acuity was 0.1 in the right eye and 0.2 in the lefte eye. Anterior segment examination and intraocular pressure was in normal range. Fundoscopic examination revealed intraretinal crystals over the posterior pole and interspersed areas of retinal pigment epithelial atrophy as filling defects on fundus fluorescein angiography (FFA) . Spectral Domain optical coherence tomography (SD-OCT) revealed outer retinal tubulations with hyperreflective spots suggestive of Bietti crystalline dystrophy. Also choroidal hyperreflective spots were noted.

Results:

Our patient suffered from visual deterioration and nyctalopia. These are common symptoms for many retinal disorders. Fundoscopic examination, FFA and OCT gave sufficient clue for differential diagnosis of Bietti Crystalline Dystrophy.

Conclusions:

Detailed fundoscopic examination and diagnostic imaging with FFA and SD-OCT are indicative evidences for diagnosis of Bietti Crystalline Dystrophy.
