Abstract
Purpose
Degenerative myopia is a significant cause of vision loss; yet there is no accepted way of controlling its causative phenotype—progressive high axial myopia. Scleral reinforcement, introduced over 50 years ago, was discredited as a useful technique. This 5-year ‘proof of concept’ study examines buckling of the posterior pole for myopia control and follows the course of untreated fellow eyes.
Method
A total of 59 adult eyes, with myopic refractive corrections ranging from −9 to −22 D and axial lengths from 27.8 to 34.6 mm, were studied. A 1-cm-wide flexible buckle of donor sclera was positioned over the posterior pole and secured, under positive tension, to the anterior globe. The eyes were monitored for 5 years, as were unsupported fellow eyes. The axial lengths, visual acuities, and optical coherence tomography macular scans were collected and all complications were noted.
Results
Over 5 years, axial length control was achieved by scleral buckling, whereas axial extension progressed in the untreated group. No serious complication occurred and no eye lost visual acuity from the procedure. Temporary intra-ocular pressure elevation, small choroidal effusions, and variable periods of abduction limitation occurred after surgery. In one case of tractional myopic macular schisis, a full correction was achieved by buckling and visual acuity improved.
