Three cryosurgical units were compared on the basis of the ability of each unit to freeze the ciliary body of enucleated normal canine eyes. The coldest average temperatures reached were -13.4 C, -4.3 C, and -17.6 C. One of the units was then used to freeze the ciliary body in the left eye of 25 dogs for 5 minutes. Ciliary body temperatures were monitored every 15 s during cyclocryosurgery. In 18 eyes in situ, the coldest average temperature reached was -13.4 C. In 7 proptosed globes, the coldest average temperature reached was -13.8 C. The results were not significantly different (P less than 0.05). The effects of the cryosurgery and centesis procedure were monitored daily by direct observation and Schiotz's tonometry. Histologic changes from the procedure were evaluated at 5 minutes, 1 week, 1 month, and 6 months after surgery. Intraocular pressure returned to the normal range within 1 to 2 weeks, the anterior uveitis subsided in 7 to 10 days, and ciliary body epithelium was histologically normal within 6 months after surgery.
基于各冷冻手术设备冷冻摘除的正常犬眼睫状体的能力，对三台冷冻手术设备进行了比较。所达到的最冷平均温度分别为-13.4℃、-4.3℃和-17.6℃。然后使用其中一台设备对25只犬的左眼睫状体进行5分钟的冷冻。在睫状体冷冻手术期间，每15秒监测一次睫状体温度。在18只原位眼中，所达到的最冷平均温度为-13.4℃。在7只眼球脱出的眼中，所达到的最冷平均温度为-13.8℃。结果无显著差异（P小于0.05）。通过直接观察和施氏眼压计每日监测冷冻手术和穿刺术的效果。在术后5分钟、1周、1个月和6个月评估该手术的组织学变化。眼内压在1至2周内恢复到正常范围，前葡萄膜炎在7至10天内消退，术后6个月睫状体上皮组织学正常。
