Retina
Cystoid Macular Edema
Two million cataract surgeries are performed annually, and the
overwhelmingly large majority of these patients have excellent outcomes with marked visual
improvement. However, 1-2% of post-cataract extraction patients develop swelling in the area
of the retina responsible for central vision (the macula).
This swelling occurs in
cystoid spaces, and is referred to as cystoid macular edema. Patients frequently describe
blurred vision after an initial improvement following surgery.
Cystoid macular edema
can occur as early as days following surgery and as late as several years. Treatment options
include observation, topical therapy, periocular injections, and surgery.
