Macular Telangiectasia (MacTel)

Macular telangiectasia [teh-LAN-jee-ek-TAY-zhuh], also called MacTel, is a rare eye disease that affects the part of the eye called the macula. The macula is a small area in the center of the retina that is responsible for sharp, straight-ahead vision. MacTel causes a slow loss of central vision, which affects vision for tasks such as reading and driving. Most people with MacTel will not lose peripheral (side) vision.
