Iatrogenic retinal breaks complicating pars plana vitrectomy.

Abstract

To determine the current incidence and outcome of iatrogenic retinal breaks occurring during pars plana vitrectomy, the authors reviewed 404 consecutive operations done on eyes without preexisting retinal breaks. Thirteen eyes had 14 iatrogenic peripheral retinal breaks. Three other eyes had both peripheral breaks and posterior breaks. Twenty-five eyes had 43 posterior breaks. The incidence of peripheral breaks was 4% and of posterior breaks was 6%. Patients with proliferative diabetic retinopathy had a higher incidence of iatrogenic retinal breaks than those with other diagnoses. Peripheral breaks occurred most commonly just posterior to the site of insertion of the vitrectomy probe. Although six eyes required reoperation, 33 of 38 eyes had a successful anatomic outcome.
