CME & Macular Edema

Macular edema occurs when fluid collects beneath the area of the retina known as the macula. The macula is the location of a person's best vision. When macular edema occurs, a person's vision declines.

CME

• The acronym CME is used for a specific type of macular edema known as cystoid macular edema. The fluid beneath the retina collects in a cyst, or small fluid filled pocket. The American Academy of Ophthalmology states that cystoid macular edema is the most common cause of decreased vision, following cataract surgery.

Macular Edema

• Macular edema can form as a result of diabetes or high blood pressure, also causing reduced vision. The fluid collects beneath the retina in a diffuse pattern. No cysts form in these types of macular edema.

Treatment

• The treatment for macular edema depends on the type. Cystoid macular edema is treated with anti-inflammatory medication. Other types of macular edema can be treated with laser therapy, eye injections or by treating the underlying condition.
