In the early stages, people with macular telangiectasia will have no symptoms.
As the disease progresses, you may have such symptoms as blurring, distorted vision, and loss of central vision. You may need brighter light to read or perform other functions. Loss of central vision progresses over a period of 10 to 20 years. Macular telangiectasia does not affect side vision and does not usually cause total blindness.
