METHODS: In this report we describe a case of bilateral sub-tenon abscess 4 weeks after medial rectus recession. Despite receiving topical antibiotics for 7 days, there was no improvement, and multiple conjunctival cultures and sensitivity showed no growth. Both eye\'s sub-tenon abscess was drained, irrigated with gentamicin, and the fragile suture was removed.
UNASSIGNED: Sub-tenon abscess has been associated with bacterial infection which has more sever presentation. Several facts, including the lack of organisms in the pre-operative and intraoperative cultures, the presence of big cells resembling foreign bodies, and the improvement that occurred after suture extrusion, make infection unlikely in this case.
CONCLUSIONS: We concluded that suture reaction is most likely to be responsible for a late-onset sub-tenon abscess with a negative culture and no response to antibiotics, and the suture should be removed.
方法:在本报告中,我们描述了一例内侧直肌衰退后4周的双侧肌腱下脓肿。尽管接受了7天的局部抗生素治疗,没有任何改善,多个结膜培养和敏感性无生长。两只眼睛的肌腱下脓肿被引流,用庆大霉素灌溉,脆弱的缝合线被移除。
■肌腱下脓肿与细菌感染有关,细菌感染具有更严重的表现。几个事实,包括术前和术中培养中缺乏生物体,类似于异物的大细胞的存在,以及缝线挤压后发生的改善,在这种情况下不太可能感染。
结论:我们得出的结论是,缝合反应最有可能是迟发性肌腱下脓肿的原因,培养物呈阴性,对抗生素没有反应。缝线应该被移除。
