Diabetic Macular Edema (DME)

Diabetes causes damage to the blood vessels near the retina which is referred to as diabetic retinopathy. In some cases, the damaged blood vessels leak blood into the retina and lead to swelling or edema in the macula also known as the central section of the retina. Macular edema can also happen after an eye surgery or inflammatory eye diseases. If diabetic macular edema is left untreated, then it may lead to loss of clear vision.

Symptoms

-blurry/ wavy vision 

-faded colors 

-increase in eye floaters 

-double vision

Diagnostic Methods

-Visual acuity test

-Dilated eye exam

-Visual acuity test

-Fluorescein angiogram

-Optical Coherence Tomography (OCT)

Treatment

-control diabetes and hypertension 

-anti-vascular endothelial growth factor (anti-VEGF) drugs: limits leakage, delivered via injection into the eye 

-focal laser: eliminated leaking blood vessels, may leave permanent blind spots

-corticosteroids: decrease DME and improve vision

Interesting - good pictures

Several comments:

- I would just say that diabetes damages blood vessels in the retina.  I know people still say that the increased blood sugar can block blood vessels, but that really isn't what is happening.

- For the diagnostic methods and the OCT image can you put a little blurb after each one describing what it means
