—I define failure as a traction retinal detachment or permanent vision loss.Thirty-five eyes were listed as failures at the end of the survey. The cut-off date was January 1982. These 34 patients were resurveyed and as of January 1984, we found that, in fact, ten had not failed.Four patients had reduced visual acuity due to the development of cataracts, but had attached and well-functioning retinae and were considering cataract extraction. Two of these four patients who had cataracts develop had actually enjoyed good vision; one patient's visual acuity improved to 20/25 for six months and the other patient's visual acuity improved to 20/50 for three years before development of the cataract.One patient had had sporadic reduction in visual acuity that returned to the 20/30 level in between vitreous hemorrhages.One patient's visual acuity improved to the 20/25 level, which was maintained for 19 months
