Acute Posterior Multifocal Pigment Epitheliopathy (APMPPE) is a rare
acquired eye disorder. Major symptoms include rapid temporary loss of vision
due to disease of the retinal pigment cells.
Symptoms
APMPPE is characterized by multiple flat, yellow-white lesions of the
posterior part of the inner eye at the pigment cell level of the retina.
There are usually signs of inflammation in the veins of the retina which
subside without treatment. In some cases the resulting vision loss can be
permanent, but in most cases the disorder is characterized by rapid but
temporary loss of vision.
Causes
The exact cause of APMPPE is not known. Researchers suspect that it may be
caused by a virus. It can subside without treatment or it may reoccur at any
time. The viruses may stay dormant in humans for extended periods of time,
then for reasons yet unknown, may unexplainably become reactivated.
Affected Population
APMPPE affects males and females of all ages in equal numbers. It is a very
rare disorder.
Related Disorders
Symptoms of the following disorders can be similar to those of APMPPE.
Comparisons may be useful for a differential diagnosis.
Retinitis Pigmentosa (RP) is one of a group of diseases causing
degeneration of the retina. When the retina degenerates, as in Retinitis
Pigmentosa, the vision decreases and may occasionally be lost. One of the
earliest symptoms is difficulty seeing at night or in dimly lit places. This
is slowly followed by tunnel vision. The rate and extent of progression is
extremely variable, but RP does not occur with the sudden onset of APMPPE.

search term in the Rare Disease Database.)
Therapies: Standard
Treatment of APMPPE is symptomatic and supportive. Very often vision returns
without specific treatment.
Therapies: Investigational
