About 96% of retinal detachments with a macular hole were cured by surgery. The most effective surgical procedure was diathermy with a macular buckling method and scleral infolding at the temporal part of the equatorial region, the rate of success being 100%. Only diathermy or diathermy plus scleral infolding at the temporal part of the equatorial region could reattach all detached retinas. Since macular buckling procedures made visual acuity worse, techniques without macular buckling should be used in cases without macular atrophy or degeneration of myopia. Retinal hemorrhage during or after operation was the most frequent complication (50%) of surgery for retinal detachment with a macular hole and occurred more frequently when macular buckling procedures were used. Macular hemorrhage caused deterioration of postoperative visual acuity.
