One serious complication of macular telangiectasia is the development of abnormal blood vessels under the retina. This is called choroidal neovascularization, and may call for injections of a drug called vascular endothelial growth factor inhibitors (anti-VEGF). Anti-VEGF medication targets a specific chemical in your eye that causes abnormal blood vessels to grow under the retina. That chemical is called vascular endothelial growth factor, or VEGF. Blocking VEGF with medication injections reduces the growth of abnormal blood vessels, slows their leakage, helps to reduce swelling of the retina, and in some cases may improve vision.

Unfortunately, sometimes treatment does not appear to offer much benefit. Clinical studies are underway to better understand the disease and identify potential useful treatments.

People who have vision loss from macular telangiectasia may find that low vision aids can help them make the most of their remaining vision.
