How is cystoid macular edema diagnosed?

Cystoid macular edema is usually diagnosed in one of three ways: dilated retinal exam, fluorescein angiography, or optical coherence tomography (OCT).

• Dilated retinal exam: Your doctor may be able to diagnose the cystoid macular edema using a special lens to see the macula and identify the cysts.
• Fluorescein angiography: Alternatively, diagnostic testing may be used to diagnose cystoid macular edema. Fluorescein angiography uses a special camera system to see leakage that results from blood vessels and the associated cystoid macular edema.
• Optical coherence tomography (OCT): OCT has become one of the best ways to diagnose and identify cystoid macular edema. OCT is a non-invasive test that uses a special light to create a high-resolution cross-sectional image of the tissues of interest, including the retina.
