MACULAR BUCKLING FOR RETINAL DETACHMENT DUE TO MACULAR HOLE IN HIGHLY MYOPIC EYES WITH POSTERIOR STAPHYLOMA

Abstract

To evaluate the efficacy of macular buckling surgery using a special exoplant.The authors reviewed 33 cases of patients with retinal detachment due to macular hole with posterior staphyloma who underwent a macular bucking procedure and 11 cases of patients with the same condition due to macular hole without posterior staphyloma or due to a hole along the edge of the posterior staphyloma who underwent gas injection or vitrectomy. The reattachment rate, visual acuity (VA), and area size (V-4, I-4 isopter) by Goldmann perimetry were calculated.Reattachment rate for the macular buckling procedure was 94% (initial) and 100% (final), and that for the gas injection or vitrectomy was 100% (both initial and final). Twenty of the 33 eyes (60.6%) had VA of 20/400 or better, and none of these 33 eyes had a VA at the level of finger counting or poorer following macular buckling. Nine of the 11 eyes (81.8%) had VA of 20/400 or better, and none of these 11 eyes had a VA at the level of finger counting or poorer following the gas injection or vitrectomy. The area size of V-4 isopter in the macular buckling group was significantly larger than that in the gas injection or vitrectomy group (P = 0.017).The macular buckling procedure is effective when considered both from an anatomic and a functional perspective for retinal detachment due to macular hole with posterior staphyloma.
