This 30 year old man experienced gradually decreasing visual acuity and increasing photophobia beginning at around ten years of age. As a young child, his best corrected visual acuity was near normal (20/30 OU).

The clinical features supporting the diagnosis of autosomal dominant cone dystrophy in this patient include: reduced acuity and photophobia as his earliest symptoms; a bull's eye appearance of the fovea with a relatively normal fundus appearance more anteriorly; loss of foveal photoreceptors on OCT; global depression of the Goldmann visual field (complete loss of the I2e isopter); and, a three generation family history of similarly affected individuals with some male to male transmission.
