THE MACULAR BUCKLING PROCEDURE IN THE TREATMENT OF RETINAL DETACHMENT IN HIGHLY MYOPIC EYES WITH MACULAR HOLE AND POSTERIOR STAPHYLOMA

Abstract

To evaluate the long-term anatomical and functional results of the macular buckling procedure in myopic macular hole with retinal detachment and posterior staphyloma. Twenty-five consecutive highly myopic eyes with retinal detachment, macular hole, and posterior staphyloma, which were operated between February 1983 and April 1992, were retrospectively studied. The last examination was in June 2002. Follow-up of the 25 patients ranged from 10 years to 19 years (mean, 15 years). Macular buckling with an episcleral sponge was the initial and only procedure. In all operated eyes, anchoring of the sponge was away from the posterior pole. Best-corrected visual acuity was evaluated before and after surgery. The axial length of the eyeball was also measured by A-scan ultrasonography before treatment. Twenty-two of 25 eyes were successfully treated with a single procedure. In the remaining three eyes, retinal reattachment was obtained after a second buckling operation, which was considered necessary due to loosing of the sponge fixation sutures in two cases and the location of the hole beside the buckle in one case. The mean overall visual acuity was improved after treatment. The macular buckling procedure with anchoring of the sponge away from the posterior segment provided efficient scleral indentation of long duration for closure of the macular hole and retinal reattachment.
