title: [Prognosis of vitrectomy].
abstract: Of 63 eyes on which vitrectomy was performed with a follow-up of at least six months 34 had an ERG with a b-wave of 50 muV or more preoperatively. Twenty-nine eyes had a b-wave of less than 50 muV. Twenty-six (76%) with an ERG > 50 muV, but only five eyes with an ERG < 50 muV had useful vision postoperatively. Of the eyes with an ERG <50 muV and without useful vision post-operatively, 75% were found intraoperatively to have a total retinal detachment. From these results it is concluded that the preoperative ERG findings are of great value for evaluating the prognosis of a vitrectomy.
