在40只正常成年食蟹猴眼中，以不同的组合进行各种直肌后徙，以评价其对眼前段的影响。这些手术分为第一、第二、第三和第四次手术（每次手术间隔数周或数月），最终涉及眼睛的所有四条直肠。在11只眼中，阻塞睫状后动脉（PCA）以确定其对眼前节的影响。所有患眼术前及术后随访期间均行裂隙灯、彩色照相、荧光素眼前节血管造影及眼压测量。这些研究表明，两条或三条直肌同时以不同的组合后退不会产生严重的永久性眼前节变化，尽管最初在一些眼睛中存在短暂的轻度至中度眼前节缺血。四个直肠同时作为一个主要的程序产生严重的永久性眼和眼前节的变化，然而，当这是作为一个二级或三级程序后，以前的三个或四个直肠的衰退，眼前节的变化要少得多，温和的比当它是一个主要的程序。所有睫状后动脉的闭塞本身并不引起眼前节的重要变化，但当合并两条水平直肌的同时后退时，它会引起严重的眼前节变化。根据这些发现，眼前段的动脉血供模式进行了讨论。
In 40 normal adult cynomolgus monkey eyes, recession of various recti in different combinations was done to evaluate their effects on the anterior segment. These procedures were done as primary, secondary, tertiary, and fourth procedures (each separated by several weeks or months), ultimately involving all four recti in the eyes. In 11 eyes, posterior ciliary arteries (PCAs) were occluded to determine its effects on the anterior segment. All eyes were examined by slit lamp, color photography, and fluorescein angiography of the anterior segment, and tonometry, before surgery and serially thereafter during the follow-up period. These studies showed that recession of two or three recti simultaneously in different combinations produced no serious permanent anterior segment changes, although initially in some of the eyes there was transient mild-to-moderate anterior segment ischemia. Recession of four recti simultaneously as a primary procedure produced serious permanent ocular and anterior segment changes; however, when this was done as a secondary or tertiary procedure after previous recessions of three or four recti, anterior segment changes were much fewer and milder than when it was a primary procedure. Occlusion of all the posterior ciliary arteries in itself produced no important changes in the anterior segment, but when combined with simultaneous recession of both the horizontal recti, it produced serious anterior segment changes. In the light of these findings, the pattern of arterial blood supply of the anterior segment is discussed.
