Pseudophakic cystoid macular edema is now an infrequent complication o
f cataract surgery. However, since cataract surgery continues to be on
e of the most commonly performed surgical procedures, the prevalence o
f pseudophakic cystoid macular edema is high. In addition, although ps
eudophakic cystoid macular edema has been a well-defined entity since
the 1950s and 1960s, little progress has been made in understanding it
s pathogenesis or in deriving an effective treatment of the condition.
While acute pseudophakic cystoid macular edema may resolve spontaneou
sly, chronic visually significant pseudophakic cystoid macular edema r
emains difficult to treat. Nonsteroidal anti-inflammatory agents and c
orticosteroids in various forms can be used, but each type of treatmen
t lacks satisfactory success. Eyes with abnormal vitreous or refractor
y to medical therapy can be improved with vitrectomy surgery. It must
be concluded, however, that there is a real need for significant advan
ces in both the understanding and treatment of pseudophakic cystoid ma
cular edema.
