Tractional retinal detachment occurs when scar tissue on the surface of the retina pulls it away from the back of the eye. It is most often linked to advanced diabetic eye disease or other conditions that cause fibrovascular membranes to form.
How traction develops
Abnormal blood vessels and scar tissue can grow on the retina and into the vitreous gel. As this tissue contracts, it exerts traction that lifts the retina, sometimes involving the macula and threatening central vision.
- Often associated with long-standing or poorly controlled diabetes
- Symptoms may include distortion, patches of blurred vision or a shadow
- Treatment usually involves vitrectomy surgery to release traction
- Early diagnosis improves the chances of preserving sight
