PERIPAPILLARY (pericentral) CHOROIDAL DYSTROPHY

Peripapillary (pericentral) Choroidal Dystrophy is a condition, which causes wasting of the blood vessels that surround the optic nerve. Patients first notice symptoms in the late adult years, when the macula is affected.

Stationary cone disorders are present at birth and have symptoms decreased acuity, decreased colour vision, sensitivity to light - that do not worsen with age. There are several types of stationary cone disorders (for example, cone monochromatism, blue cone monochromatism, dichromatism, trichromatism) with differing prognoses for visual acuity.
