RESULTS OF RETINAL-DETACHMENT SURGERY IN PSEUDOPHAKIA

Between 8/81 and 9/89 2658 patients underwent retinal detachment surgery at the university eye hospital Erlangen/Nurnberg. From this number there were 30 (= 1.1%) pseudophakic retinal detachments consisting of 14 males and 16 females. Minimal age was 48, maximal 89 years, average age was 70.9 years. There were 4479 extracapsular cataract extractions with implantation of a posterior chamber lens performed in the same interval at our eye hospital. Out of this 4479 extra-capsular cataract extractions we found 9 patients (= 0.2%) with pseudophakic retinal detachment. In our investigated group we found preoperative risk factors resulting in a pseudophakic retinal detachment consisting out of myopia, latticelike degeneration of the retina and contusio bulbi. Intraoperative risk factors are the rupture of the posterior capsule and vitreous prolapse. A postoperative risk factor is YAG-laser-capsulotomy. We observed a pseudophakic retinal detachment with patients undergoing YAG-laser-capsulotomy after minimal 30, maximal 880 and 372 days in average. Out of 30 patients 17 (= 66.6%) were treated successfully with the first operation. The success rate summed up to 83.2% after one re-operation. With 17 out of 30 patients we had to apply extensive endoophthalmic vitreous and retinal surgical techniques (cerclage, pars-plana-vitrectomy, silicone oil instillation).
