偽黄斑円孔の光干渉断層計所見と臨床像

Clinical features and findings by optical coherence tomography of macular pseudoholes

要約　目的：偽黄斑円孔の臨床像と光干渉断層計（OCT）による所見の報告。対象：偽黄斑円孔の自験例21例21眼を診療録の記載に基づいて検索した。男性6例，女性15例である。10例には手術を行い，11例では経過のみを追跡した。結果：手術群では術後の矯正視力が有意に改善し（p＜0.05），黄斑厚は有意に増加した（p＜0.05）。視力の改善と黄斑厚とは相関しなかった。OCTによる黄斑の術後の形状は，7眼で改善し，3眼で不変であった。非手術群では，平均31.5か月の観察期間内で有意な視力変化はなく，OCTによる黄斑形状には変化がなかった。結論：偽黄斑円孔では，硝子体手術による黄斑形状と視力改善が期待できるが，手術適応はさらなる検討が必要である。

Abstract.　Purpose：To report the clinical features and findings by optical coherence tomography（OCT）of macular pseudoholes. Cases：This retrospective study was made on 21 eyes of 21 cases who were diagnosed with macular pseudohole. The series comprised 6 males and 15 females. Ten eyes were treated by surgery. The other 11 eyes were followed up without surgery. Results：After surgery,corrected visual acuity significantly improved（p＜0.05）and macular thickness significantly increased（p＜0.05）. There was no correlation between visual acuity and macular thickness after surgery. Findings of macular pseudohole by OCT improved in 7 eyes and remained unchanged in 3 eyes. In 11 eyes that received no surgery,there was no change in visual acuity or in the shape of pseudohole when seen by OCT during the follow-up for an average of 31.5 months. Conclusion：In macular pseudoholes,morphology of the macula and visual acuity may improve after vitreous surgery. Findings by OCT do not serve as a guide in the decision of indication for surgery.
