本文观察了２８眼小梁切除术及１０眼虹膜周边切除术前、后眼球上转度数的变化。小梁切除术组上直肌牵引时间为２８±１１分钟，术后眼球上转度数较术前减少近１０°，术后７天恢复至术前水平。虹膜周边切除术组上直肌牵引时间为１２±５分钟，术后眼球上转度数较术前减少５°，术后４天恢复至术前水平。提示术后眼球上转障碍为上直肌功能性损伤所致，损伤程度与上直肌牵引时间有关。 This article observed the 28 trabeculectomy and 10 iridectomy before and after the eyeball changes in the number of degrees. Traction of the rectus muscle in trabeculectomy group was 28 ± 11 minutes. The number of rotations on the eyeball decreased by 10 ° compared with that before operation, and returned to preoperative level 7 days after operation. The rectus traction time of the iris peripheral resection group was 12 ± 5 minutes, and the number of rotations on the eyeball after operation decreased by 5 ° compared with the preoperative level, and returned to the preoperative level 4 days after the operation. Prompted postoperative eyeball up obstacles for the upper rectus injury caused by the degree of injury and the upper rectus traction time.
