[Placoid epitheliopathy and serpiginous choroidopathy]

Both acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and geographic or serpiginous choroiditis are probably the result of a primarily inflammatory involvement of the choroid. In the acute phase both diseases may present a similar appearance. The evolution is however quite different. APMPPE usually affects younger individuals and is almost always bilateral; both eyes are often affected simultaneously. In geographic choroiditis the second eye is sometimes involved weeks up to years after the first eye. APMPPE may be considered as the ocular manifestation of a systemic disease possibly induced by a viral infection. The etiology of geographic choroiditis is still unknown.
