Geographical choroidopathy

Abstract

Geographical choroidopathy appears to be a distinct clinical entity in which there are acute, well-defined lesions affecting the pigment epithelium. During the evolution of the lesion, which occurs over several months, there is no change in its shape or size. The disease progresses over several years, and is characterized by the occurrence of further acute lesions. Nineteen patients with this disease entity have been seen at Moorfields Eye Hospital. Five patients are described in detail; the fundus appearances are identical and in each case the disease affected both eyes. The aetiology is unknown.
