Cystoid Macular Edema
Cystoid macular edema (CME), or swelling of the macula, typically occurs
as a result of disease, injury or more rarely, eye surgery. Fluid
collects within the layers of the macula, causing blurred, distorted
central vision. CME rarely causes a permanent loss of vision, but the
recovery is often a slow, gradual process. The majority of patients
recover in 2 to 15 months. In this retinal photograph, the swelling is
the yellowish spots (arrow) in the macula.
SIGNS AND SYMPTOMS
•Blurred central vision
•Distorted vision (straight lines may appear wavy)
•Vision is tinted pink
DETECTION AND DIAGNOSIS
It is very difficult to detect CME during a routine examination. A
diagnosis is often based on the symptoms of the patient and a special
dye test called a fluorescein angiogram (FA).
The first line of treatment for CME is usually anti-inflammatory drops.
In certain cases, medication is injected near the back of the eye for a
more concentrated effect. Oral medications are sometimes prescribed to
reduce the swelling.
