Anterior segment ischemia 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. They 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 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 is described in detail. Also, some unanswered queries, such as the duration of the reaction and the time interval of the reaction after multiple muscle surgeries, are discussed.
前段缺血性改变可在未切断任何眼外肌的情况下发生。前段发生此类缺血性改变的最常见原因是在一次手术中切除过多的直肌。对20只犬眼和8只猴眼进行了不同组合的眼外肌离断和切断术。在术后30至90天的不同时间点将它们处死。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2例在肌肉手术后接受前段缺血研究、观察和治疗的患者。肌肉手术后发生的改变广泛，包括角膜水肿、白内障、球结膜水肿、角膜改变、眼压降低、房水流出减少或青光眼以及明显的坏死。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，如反应持续时间以及多次肌肉手术后反应的时间间隔。
