Anterior segment ischemic changes can occur without detachment of any muscles. The most common cause of such ischemic changes of the anterior segment is the removal of too many rectus muscles in one operation. Twenty dog eyes and eight monkey eyes were subjected to the disinsertion and detachment of various combinations of extraocular muscles. The dogs were sacrificed at intervals from 30 to 90 days. During the observation period, they were observed for gross and slit-lamp changes. The enucleated eyes were studied microscopically for signs of ischemic and necrotic changes. Two patients who were studied, observed, and treated for anterior segment ischemia following muscle surgery are described. The changes which occur after extraocular muscle surgery are extensive and include corneal edema, cataract, chemosis, corneal changes, decreases in intraocular pressure, decreases in outflow or glaucoma, and frank necrosis. The variables which lead to this reaction are described in detail. Also, some unanswered queries, such as the duration of the reaction and the time interval of the reaction after multiple muscle operations are discussed.
前段缺血性改变可在未分离任何肌肉的情况下发生。前段此类缺血性改变最常见的原因是在一次手术中切除过多的直肌。对20只犬眼和8只猴眼进行了不同眼外肌组合的离断和分离操作。犬在30至90天的间隔期内被处死。在观察期内，对其进行肉眼和裂隙灯检查。对摘除的眼球进行显微镜检查，以寻找缺血和坏死改变的迹象。描述了两名在肌肉手术后因前段缺血接受研究、观察和治疗的患者。眼外肌手术后发生的改变广泛，包括角膜水肿、白内障、结膜水肿、角膜改变、眼压降低、房水流出减少或青光眼以及明显坏死。详细描述了导致这种反应的变量。此外，还讨论了一些未解决的问题，如反应的持续时间以及多次肌肉手术后反应的时间间隔。
