acute posterior multifocal placoid pigment epitheliopathy
Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) is an acquired, inflammatory eye condition affecting the retina, retinal pigment epithelium (pigmented layer of the retina), and choroid. It usually affects both eyes and is characterized by multiple, yellow-white lesions in the back of the eye. The condition can significantly impair visual acuity if the macula is involved. APMPPE typically resolves on its own in weeks to months. While the cause is unknown, about a third of cases appear to develop after a flu-like illness. Non-ocular symptoms are uncommon, but cerebral vasculitis can be present and may cause permanent and/or severe neurological complications.
