Survey of patients treated by vitreous surgery for idiopathic macular holes

（24M-1）　硝子体手術を行った片眼性特発性黄斑円孔患者61例について自覚症状のアンケート調査を実施し，51例で回答を得た。術前の自覚症状としては変視症（75％），中心暗点（69％），視力の低下（69％）が多かった。これらの症状は術後各々72％，64％，62％で．自覚的に改善した。術前に遠近感や立体感の低下を自覚したものは約30％と少なかった。術後の自覚症状が「大幅に改善した」と回答したものは，発症から6か月未満の新鮮例や円孔サイズ600μm未満の円孔や術後視力0.6以上の症例に多かった。手術を受けて良かったとする満足度は88％であった。

We surveyed 61 patients treated by vitreous surgery for unilateral idiopathic macular hole by sending a questionnaire. Response was obtained from 51 patients, 84%. Preoperative subjective symptoms comprised metamorphopsia 75%, central scotoma 69% and blurred vision 69%. Impaired sense of perspective or stereopsis had been noted in 30%. After surgery, metamorphopsia improved in 72%, central scotoma in 64% and blurred vision in 62%. The incidence of remarkable improvement in symptoms was more frequently noted by patients when the condition had persisted for 6 months or less until surgery, the hole size was 600 i m or less, or the postoperative visual acuity was 0.6 or better. The postsurgical state was evaluated as satisfactory by 88% of the cases.
