特発性黄斑円孔と特発性黄斑上膜に対する内境界膜剥離後の網膜神経線維層欠損様所見

Retinal nerve fiber layer defect after vitrectomy and internal limiting membrane peeling for idiopathic macular hole and epiretinal membrane

　硝子体手術を特発性黄斑円孔35眼と特発性黄斑上膜45眼に行い，術後の網膜神経線維層欠損について検索した。検索には走査レーザー検眼鏡を併用した。内境界膜剥離術を黄斑円孔20眼と黄斑上膜23眼に対して同時に行った。網膜神経線維層欠損は黄斑円孔12眼と黄斑上膜14眼に生じ，内境界膜剥離術が黄斑円孔12眼すべてと黄斑上膜13眼に行われていた。黄斑円孔と黄斑上膜各群における内境界膜剥離術の有無は，術後6か月までの視力と網膜感度に有意に相関しなかった。

We performed vitrectomy on 35 eyes of idiopathic macular hole and on 45 eyes of idiopathic epiretinalmembrane. These eyes were evaluated regarding postoperative retinal nerve fiber layer defect (NFLD) usinga scanning laser ophthalmoscope (SLO) among others. Additional peeling of internal limiting membrane (ILM)was performed on 20 eyes of macular hole and 23 eyes of epiretinal membrane. NFLD developed in 12 eyes ofmacular hole and 14 eyes of epiretinal membrane. ILM peeling had been performed in all the 12 eyes of macularhole and 13 eyes of epiretinal membrane. In either group of macular hole and epiretinal membrane, ILM peelingdid not significantly affect the visual acuity or central retinal sensitivity up to postoperative 6 months.
