Abstract

Most of the macular hole retinai detachinents are limited to the perimacular area. Therefore, we must look for the peripheral retinal hole when the macular hole retinal detachment extends beyond equator. And the principle of operation should be on the peripheral retinal hole rather than macular hole. Authors studied the clinical feature of macular hole retinal detachment associated with the peripheral retinal hole. Among the 39 macular hole retinal detachment patients, peripheral hole was found in 12 patients (30.7%). Sex distribution was the same and mean age was 55.9 years old. Retinal detachment was not diagnosed for more than I month in 7 cases (58.4%). Nine cases (75.0%) were extensive retinal detachments extending beyond 3 quardrants. Nine cases (75.0%) had one peripheral hole and most of peripheral holes were found on the ternporal side. Associated diseases were cataract (5 cases, 38. 5%) and high myopia (5 cases, 38.5%). In 4 cases (33.3%) hole was found on the opposite side. Among the 12 macular hole retinal detachment patients, 11 operations were performed with the technique of gas injection and scleral buckling which lead to successful attachment in 5 cases (41.7%). Among the 7 cases in which reoperations were needed, 3 cases (42.9%) were recurred in 3 months. In 8 cases (66.7%) there were improvements of post-operative visual acuity.
