title: [Retinal detachment caused by a tear at the ora serrata].
abstract: The results of a retrospective analysis of forty eight retinal detachments with dialysis observed in 43 patients are consistent with the data of the literature. 90.7% of the patients were under 40 years of age, and 40.2% were less than 20 years old. Thirty-three eyes (68.7%) had a single dialysis, 15 eyes (31.3%) had two separate dialysis, 30 of the 64 dialysis (46.9%) were located in the inferotemporal quadrant, 18 (28.1%) in the superotemporal quadrant, 8 (12.5%) in the superonasal quadrant, and 7 (11%) in the inferonasal quadrant. Fifty dialysis (78.1%) were less than 90 degrees in size, 9 (14%) were 90 degrees in size and 5 (7.8%) extended on 100 degrees to 150 degrees. Seventeen retinal detachments (37%) were associated with subretinal gliosis. Four eyes (8.3%) showed an avulsion of the vitreous base. One single eye (2%) had a posterior vitreous detachment. None of the retinal detachments was associated with clinical evidence of preretinal proliferative retinopathy. Fourty six retinal detachments were operated on. Surgical success was achieved in all eyes. Postoperative visual acuity of 20/40 or better was achieved in 37.8% of the eyes, 54% of the eyes whose maculae were preoperatively attached, 58% of the eyes whose maculae were preoperatively detached without clinical evidence of cystic degeneration and none of the eyes whose maculae showed preoperative evidence of cystic degeneration.
