Macular telangiectasia
Macular Telangiectasia (pronounced: ma-cu-lar tel-an-ji-ec-ta-sia), also known as MacTel, is a degenerative eye disease that affects the macula, the part of the retina responsible for central, detailed vision.
Etymology
The term "Macular Telangiectasia" is derived from the words "macula", referring to an area near the center of the retina, and "telangiectasia", a term of Greek origin meaning "end of a vessel".
Description
Macular Telangiectasia is characterized by abnormal blood vessels in the macula. These vessels can leak fluid or bleed, leading to swelling and damage to the macula. This can cause a gradual loss of central vision, which can affect activities such as reading, driving, and recognizing faces.
Types
There are two types of Macular Telangiectasia:
- Type 1 Macular Telangiectasia: This is a rare form of the disease, typically affecting only one eye. It is characterized by dilated blood vessels on the surface of the retina, which can lead to fluid accumulation and swelling.
- Type 2 Macular Telangiectasia: This is the more common form of the disease, typically affecting both eyes. It is characterized by abnormal blood vessels growing into the macula, which can lead to the formation of a scar and loss of vision.
Symptoms
Symptoms of Macular Telangiectasia may include:
- Blurred or distorted vision
- Difficulty reading or recognizing faces
- A gray or empty area in the center of vision
- Sensitivity to glare
Diagnosis
Diagnosis of Macular Telangiectasia is typically made through a comprehensive eye examination, which may include a fluorescein angiography or optical coherence tomography scan.
Treatment
While there is currently no cure for Macular Telangiectasia, treatments are available to manage symptoms and slow the progression of the disease. These may include laser therapy, anti-VEGF therapy, or vitrectomy.
