Causes of macular edema
Macular edema can respond to many causes, although diabetes is one of the most frequent. It can also have other causes, such as vein thrombosis of the retina, ocular inflammation, after undergoing surgery, or degenerative diseases such as age-related macular degeneration (AMD) .
The symptoms that macular edema can present are usually blurred vision, although these tend to be painless, discolored vision and even a significant loss of vision.

In most cases, the affected person will need a treatment that will range from eye drops, intraocular injections of anti- inflammatory or anti- pathogenic drugs, to one that requires laser technique, and may even need to be treated with surgery in cases where there is traction on the retina.
