• Functional and anatomic success after relaxing retinotomy may be limited by recurrent retinal detachment or severe hypotony. Fifty-four consecutive eyes undergoing relaxing retinotomy for proliferative vitreoretinopathy (42 eyes) and trauma (12 eyes) were analyzed to determine whether perioperative factors, including size and location of the retinotomy, influenced visual or anatomic outcome. After 6 months' minimum follow-up, anatomic success (retina attached posterior to buckle and an intraocular pressure of 3 mm Hg or more) was achieved in 35 eyes (64%). Functional success (visual acuity of 5/200 or better) was achieved in 14 eyes (26%). Factors predicting functional success by stepwise logistic regression analysis included a preoperative visual acuity of hand motions or better and location of the retinotomy in the superior four clock hours of the fundus. Causes of anatomic failure included proliferative vitreoretinopathy (11 eyes) and severe hypotony or phthisis (8 eyes). Superior location of the retinotomy and visual acuity of hand motions or better favorably influenced visual outcome after relaxing retinotomy.
