    Macular telangiectasia fact sheet

    A free resource with information on MacTel.

    Macular telangiectasia (MacTel) is a disease that affects the macula, causing central vision loss. It’s caused by abnormal blood vessels around the fovea. The fovea is the centre of the macula and is used for detailed central vision.

    In its early stages, people with macular telangiectasia may not have symptoms. As the disease progresses over 10 to 20 years, there may be blurriness and distortion of central vision depending on the severity of the disease. Side or peripheral vision is usually unaffected. 

    This fact sheet discusses the two types of MacTel, symptoms, diagnosis and treatment.
