Macular Telangiectasia (MacTel) is a disease that affects the macula, the part of the eye responsible for detailed, central vision. The disease is characterized by telangiectasia, or abnormal blood vessels, in the macula.
Symptoms[edit]
The symptoms of Macular Telangiectasia can vary, but often include:
- Blurred vision
- Distorted vision
- Trouble reading or performing tasks that require the ability to see detail
- A blind spot in the center of the visual field
Causes[edit]
The exact cause of Macular Telangiectasia is unknown, but it is thought to be related to changes in the blood vessels of the macula. Some researchers believe that it may be caused by a combination of genetic and environmental factors.
Diagnosis[edit]
Macular Telangiectasia is diagnosed through a comprehensive eye examination. This may include:
- A visual acuity test
- A dilated eye exam
- Fluorescein angiography
- Optical coherence tomography
Treatment[edit]
There is currently no cure for Macular Telangiectasia. Treatment focuses on managing the symptoms and slowing the progression of the disease. This may include:
Prognosis[edit]
The prognosis for individuals with Macular Telangiectasia varies. Some people may experience a slow progression of the disease, while others may experience a rapid loss of vision.
