X-LINKED CONE-ROD DYSTROPHY

X-linked Cone-Rod Dystrophy is a rare disorder, and patients present with decreased central vision, may have a bull's eye lesion in the macula, a fine nystagmus, and no or very little pigmentary change in the fundus, until advanced stages of the disease. The visual field loss is slower than in x-linked RP, the ERG shows a cone-rod pattern if the ERG is recordable, which is often the case: unlike x-linked RP, in which the ERG is severely affected early in the disease.
