特発性黄斑上膜の術前OCT所見と術後視力の関係

Relation between preoperative findings by optical coherence tomography and postoperative visual acuity in idiopathic epiretinal membrane

　特発性黄斑上膜15眼に硝子体手術を行い，術前の光干渉断層計（optical coherence tomogra—phy：OCT）による所見と，術前後の視力，蛍光眼底造影所見との関達を検索した。12眼には同時に水晶体乳化吸引術と眼内レンズ挿入を行った。他の3眼はすでに偽水晶体眼であった。術前の中心窩厚と手術6か月後の対数視力の間には有意な相関があった（r＝−0.53,p＝0.04）。術前の蛍光眼底造影で黄斑部に色素漏出がある6眼では，漏出のない7眼よりも術後視力が有意に悪く（p＝0.03），術後の中心窩厚も有意に厚かった。

Vitreous surgery was performed on 15 eyes of idiopathic epiretinal membrane. We evaluated the correla-tion between findings by optical coherence tomography (OCT) and postoperative visual acuity. Twelve eyes also re-ceived phacoemulsification and intraocular lens implantation. The other 3 eyes were pseudophakic at the time of sur-gery. There was a significant correlation between the preoperative foveal thickness and logrithmic value of visual acu-ity 6 months after surgery (r=-0.53, p=0.04). Fluorescein angiography showed dye leakage in the macular area in 6 eyes and no leakage in 7 eyes. The postoperative logarithmic value of visual acuity was significantly poor in the for-mer 6 eyes than in the latter 7 eyes (p= 0.03). The postoperative foveal thickness was significantly greater in the for-mer than in the latter (p=0.01).
