Vitreomacular Traction

Vitreomacular traction (VMT) occurs when the vitreous gel, which normally separates from the retina with age, remains abnormally attached to the macula and pulls on it. This traction can distort the macular surface, causing visual symptoms. VMT can lead to more serious conditions including macular hole formation and macular edema. Symptoms include blurred or distorted central vision, difficulty reading, and straight lines appearing wavy. Mild VMT may resolve on its own as the vitreous eventually releases. For persistent or symptomatic cases, treatment options include intravitreal injection of ocriplasmin (a medication that can dissolve the adhesion) or vitrectomy surgery to relieve the traction.
