VISUAL OUTCOME AFTER SURGERY FOR PETERS ANOMALY

The authors reviewed the charts Of 22 patients with Peters' anomaly Va rious surgical procedures were performed on 30 eyes of I8 patients mea n number of procedures = 3.3 per eye). Follow-up averaged six years. V isual acuity varied widely, with six eyes having an acuity of 20/400 o r better, and II eyes with no light perception. Concomitant or seconda ry glaucoma required a greater number of surgical procedures (4.I vs 3 -4) per eye and was associated with a poorer visual outcome. No eyes w ith glaucoma had visual acuity better than 20/400. In bilaterally oper ated patients, visual results in one eye were independent of the outco me of the fellow eye. The range of visual acuity in bilaterally operat ed patients was similar to the vision in those operated unilaterally. Visual outcome in patients with Peters' anomaly remains guarded. With modern surgical techniques and aggressive attempts at visual rehabilit ation, many patients may benefit from surgery. Some patients may have moderately good visual acuity for months or years before vision is los t. In the interim they may learn tasks they may not have otherwise acq uired.
