Is MacTel genetic?

Macular Telangiectasia Type 2 (MacTel) is a rare degenerative retinal disease with complex genetic architecture.

How serious is vitreomacular traction?

Sometimes, the vitreous doesn’t come away completely, leaving some of the gel attached and pulling on the macula. This then results in vitreomacular traction (VMT). If this condition is left untreated, the damage can lead to a macular hole and vision loss.

Can vitreomacular traction resolve itself?

Treatment and prognosis Some cases of VMT may spontaneously resolve. For patients whose symptoms are severe enough to require intervention, pars plana vitrectomy surgery is one treatment option.

What is Coat’s Disease?

Coats disease was first described in 1908 and is a rare disorder characterized by abnormal development of the blood vessels in the retina. The retina is a nerve-rich tissue lining the back of the eye that transmits light images to the brain, which allows a person to see.

Is vitreomacular traction an emergency?

Vitreomacular adhesion (VMA) can be serious, but it’s treatable. It involves two parts of your eye. One is the vitreous, or the “jelly” part that fills the eyeball. The other is the macula, a small area on the retina responsible for the central part of your field of vision.

When do you treat vitreomacular traction?

How is Vitreomacular Traction Syndrome treated? Treatment is not necessary if symptoms are mild. When vitreomacular traction causes vision loss or the symptoms start to interfere with a persons normal daily activities, then surgery is recommended.
