Spectral domain optical coherence tomography findings in bilateral peripheral cone dystrophy
Introduction To report spectral domain optical coherence (OCT) tomography findings in a case of bilateral peripheral cone dystrophy. Case Report A 21-year-old man complained of blurred visual fields on the lateral sides of both eyes. The patient’s best-corrected visual acuity was 20/20 in both eyes. Fundus examination revealed mild temporal pallor, while fluorescein angiography did not show any abnormalities. Humphrey’s visual field revealed a C-shaped scotoma. Photopic electroretinogram (ERG) and 30-Hz flicker revealed decreased cone function; however, scotopic ERG noted a normal response. Multifocal ERG revealed a relatively well-preserved macular area but with reduced amplitude in the ...
