Using the labeled microsphere impaction technique, we studied the effect of peripheral panretinal transscleral cryocoagulation in pigmented rabbits. One eye of each animal received peripheral cryocoagulation, and the fellow eye of the same animal was used as the control. Thirty-two animals received 40 exposures of peripheral cryocoagulation; twenty-six rabbits received 20 exposures. After 40 exposures of cryocoagulation, choroidal-retinal blood flow was significantly decreased when measured at one to two hours, 24 hours, and two weeks; normal flow recovered by four weeks. After 20 exposures of cryocoagulation, there was a significant reduction in choroidal-retinal blood flow at the earliest measurement time (one to two hours) only. The iris-ciliary body blood flow also was substantially decreased only at the earliest measurement time (one to two hours) and only after 40 exposures.
我们使用标记微球撞击技术，研究了周边全视网膜经巩膜冷凝术对有色家兔的影响。每只动物的一只眼睛接受周边冷凝术，而同一只动物的另一只眼睛作为对照。32只动物接受了40次周边冷凝术暴露；26只兔子接受了20次暴露。在进行40次冷凝术暴露后，在1至2小时、24小时和两周时测量，脉络膜-视网膜血流显著减少；四周时恢复正常血流。在进行20次冷凝术暴露后，仅在最早的测量时间（1至2小时）脉络膜-视网膜血流有显著减少。虹膜-睫状体血流也仅在最早的测量时间（1至2小时）且仅在40次暴露后大幅减少。
