Macular Telangiectasia Treatment
Over the years, researchers have studied many macular telangiectasia (MacTel) treatments. None have proven to significantly improve vision. Since the disease has a relatively good prognosis, most patients may not need treatment.
In certain cases, laser treatments may help seal leaking vessels. This treatment is less preferred because of potential harmful secondary effects. In other instances, ophthalmologists may treat MacTel with injections of steroids or other medicines.
One serious complication of MacTel is the growth of abnormal blood vessels under the retina. This is called choroidal neovascularization. Injections of a drug called vascular endothelial growth factor inhibitors (anti-VEGF) may help.
Anti-VEGF medicine targets a chemical in your eye that causes abnormal blood vessels to grow under the retina. That chemical is called vascular endothelial growth factor, or VEGF. These injections reduce the growth of abnormal blood vessels, slow leakage, and help reduce swelling. In some cases, this treatment may even improve your 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.
Low vision aids can help people with MacTel make the most of their remaining vision.
