Evaluation of the peripheral visual field after foveal translocation

PURPOSE: To evaluate the peripheral visual field after foveal translocation with scleral imbrication or 360-degree retinotomy. METHODS: Retrospective, single-center, nonrandomized study. We calculated t he rate of preservation of the peripheral visual field using Goldmann perim etry by dividing the width of the postoperative V-4 isopter by the preopera tive width and expressing the result as a percents age. RESULTS: In nine eyes that underwent scleral imbrication, the rate of prese rvation was 100.0% superiorly, 102.6% superotemporally, 99.9% temporally, 9 7.9% inferotemporally, 96.9% inferiorly, 82.3% inferonasally, 93.7% nasally , and 87.3% superonasally. In 33 eyes that underwent 360-degree retinotomy, it was 89.1%, 87.0%, 81.9%, 78.1%, 86.6%, 90.0%, 89.9%, and 86.8%, respect ively. CONCLUSION: After foveal translocation with scleral imbrication, the periph eral visual field was preserved except for slight narrowing nasally; 360-de gree retinotomy resulted in preservation of the visual field, except for sl ight narrowing in all meridians.
