A new look at pleoptics.
Sixty-four patients who did not respond adequately to passive conventional occlusion were treated with active pleoptic therapy, and followed with orthoptic therapy when fusion potential was demonstrated. Patients ranged in age from 4 to 17 years, and ranged in visual acuity from 20/30 to 20/100. Seventeen patients had some fusion prior to starting pleoptics. All 64 patients achieved an immediate post-therapy acuity of 20/30 or better; 25 were fusing and demonstrated some stereopsis. Twenty-seven patients were followed for a period of one to ten years, including the 25 patients who were fusing at completion of therapy. Twenty-four (88%) maintained visual acuity of 20/30 or better. All fused either normally or with ARC. Three patients, whose visual acuity dropped to 20/50, had no fusion. Only one patient who had fusion at the completion of therapy was unable to maintain it. We conclude, therefore, that pleoptics retains values in the treatment of amblyopic patients with steady and unsteady central fixation, in those situations where conventional occlusion in unsuccessful.
