Factors associated with visual acuity outcomes after vitrectomy for diabetic macular edema: diabetic retinopathy clinical research network.

Purpose: To evaluate factors ¶associated with favorable outcomes after vitrectomy for diabetic macular edema.

Methods: Data were collected prospectively on 241 eyes undergoing vitrectomy for diabetic macular edema. Multivariate models were used to evaluate associations of 20 preoperative and intraoperative factors with 6-month outcomes of visual acuity and retinal thickness.

Retinal endovascular surgery for central retinal vein occlusion: initial experience of four surgeons.

Purpose: The rate and magnitude of spontaneous visual recovery are very poor in central retinal vein occlusion (CRVO). In the first follow-up year, the Central Vein Occlusion Study Group reported that only 6% of eyes recovered > or = 3 lines of vision and none recovered > or = 8 lines of vision. Retinal endovascular surgery (REVS) is vitrectomy followed by cannulation of retinal vessels with injection of tissue plasminogen activator.
