Vitrectomy for progressive macular traction associated with proliferative diabetic retinopathy.

A small group of eyes with proliferative diabetic retinopathy develop progressive macular traction characterized by partial vitreous detachment with vitreo-retinal traction along the arcades and disc, retinal traction lines extending through the fovea, and progressive visual loss. Vitrectomy may be helpful in stabilizing selected eyes and actually improving visual acuity.
