Retinal detachment following penetrating keratoplasty
D. C. Musch, R. F. Meyer, A. Sugar and A. K. Vine
The time-related risk of retinal detachment during the follow-up of 1146
penetrating keratoplasty procedures was evaluated, using survival analysis
techniques. Twenty-eight retinal detachments were observed during
follow-up. The Kaplan-Meier estimate of the risk of developing retinal
detachment increased from 1.5% at three months to 2.1% at one year after
surgery. Further follow-up showed a gradual increase in the cumulative
proportion developing retinal detachment to 4.7% at 3.5 years after
surgery. Of the preoperative and intraoperative factors available for
study, performing an anterior vitrectomy during penetrating keratoplasty
was associated with a greater risk of postoperative retinal detachment. The
outcome of visual acuity following retinal detachment in these patients'
eyes was poor; five patients could not perceive light with the affected
eye, and 82% (23/28) had visual acuity of 20/200 or less.
