要約 目的:シャンデリア照明を併用した強膜内陥術後に急性感染性眼内炎を生じた症例を報告する。
症例:55歳,女性。20XX年4月上旬から右眼の飛蚊症を自覚し,近医を受診したところ,右眼の裂孔原性網膜剝離を指摘され関西医科大学附属病院(当院)を紹介され受診となった。当院初診時の右眼矯正視力は0.8,下方周辺部の限局性網膜剝離であったため,受診の翌日に広角観察システム,シャンデリア照明を併用した強膜内陥術を施行した。シャンデリアは上方に設置し,術中合併症はなかった。術後1日目は上方に結膜浮腫を認めていたが,網膜は復位していた。術後2日目に黄白色の眼脂,上方結膜浮腫の増悪と硝子体腔にフィブリンの析出を認めたため,術後感染性眼内炎と判断して同日に水晶体摘出併用硝子体手術を施行した。バックルは除去せずに硝子体を切除し,シリコーンオイル注入を行った。眼内レンズは挿入しなかった。硝子体液からは塗抹培養にてメチシリン感受性表皮ブドウ球菌が検出された。術後,徐々に眼底の透見性は改善し,6日目には透見明瞭となった。再手術から約3か月後に,シリコーンオイルを抜去し,眼内レンズ挿入術を施行した。術後6か月後の現在,右眼矯正視力は1.2と改善しており,経過は良好である。
結論:裂孔原性網膜剝離に対するシャンデリア照明を併用した強膜内陥術では,急性感染性眼内炎のリスクを念頭に置いて手術を行う必要がある。
Abstract Purpose:To report a case of acute endophthalmitis after scleral buckling surgery using chandelier endoillumination.
Case:A 55-year-old woman noticed floaters in her right eye in early April 20XX. She visited an ophthalmology clinic and was transferred to our hospital due to rhegmatogenous retinal detachment in her right eye. At the first visit to our hospital, the best corrected visual acuity of the right eye was 0.8. Because there was localized retinal detachment in the lower peripheral area, she underwent scleral buckling surgery using a non-contact wide-angle viewing system and chandelier endoillumination. The buckling surgery was completed without any intraoperative complications. On the first day after the operation, conjunctival chemosis at the superior area was observed, but the retina was well reattached. On the second day, a yellowish white discharge on the surface of the right eye and fibrin net in the vitreous body were detected. We diagnosed the case as postoperative endophthalmitis and performed vitrectomy with lens extraction on the same day. As much of the vitreous body as possible was removed and silicone oil was injected at the end of the surgical procedure. Methicillin-sensitive Staphylococcus epidermidis was detected on a culture of the vitreous specimen. On the sixth day after the re-operation, the fundus became clearly visible. Approximately 3 months after the re-operation, the silicone oil was removed and an intraocular lens insertion was performed. Her corrected visual acuity of the right eye was 1.2.
Conculusion:Suegeons should be mindful of infectious endopthalmitis when performing scleral buckling surgery with chandelier endoillumination.
