92 pseudophakic retinal detachments were treated in our hospital over a period of six years. These cases are reviewed retrospectively, with special emphasis on the factors that influenced the surgical outcome. The overall rate of success was 80%. Visual acuity was better than 0.1 in 77% of the cases. The major cause of failure was proliferative vitreoretinopathy, which was responsible for seven of ten failures. Postoperative proliferative vitreoretinopathy was the only factor that gave a significantly poorer prognosis after surgical treatment, although the presence of high myopia and preoperative proliferative vitreoretinopathy tended to give a less successful outcome. Likewise, there was a tendency for better prognosis in eyes with posterior chamber intraocular lenses.
