Progression of choroidal atrophy in acute posterior multifocal placoid pigment epitheliopathy.

Acute posterior multifocal placoid pigment epitheliopathy is a non-granulomatous chorioretinitis of uncertain origin that occurs in healthy young adults. The prevailing opinion is that the disease has a good long-term prognosis for visual acuity because it is self-limiting and chorioretinal scars do not enlarge with time. A middle-aged adult male who had acute posterior multifocal placoid pigment epitheliopathy in one eye has been followed for 22 years.

Pattern dystrophies of the retinal pigment epithelium.

Pattern dystrophies of the retinal pigment epithelium are infrequent fundus abnormalities arranged in various patterns of dots, lines and branches. The basic lesion appears to be yellow deposits of abnormal lipofuscin accumulated within degenerated retinal pigment epithelium cells. Examinations were carried out on two families who had developed different patterned alterations in the retinal pigment epithelium.
