Previous studies suggested that krypton laser photocoagulation was more effective in the treatment of macular diseases than argon laser. Furthermore, it could perform photocoagulation more effectively in some lesions with subretinal hemorrhage, because the krypton laser beam was poorly absorbed by hemoglobin. In the present experiment, hemorrhagic retinal detachment was produced in monkey eyes with Q-switched Nd-YAG laser, and 4 weeks later photocoagulation was performed with krypton and argon lasers to compare the differences in the effects of these two lasers. When the subretinal hemorrhage and a heavy coagulation effect was produced in the detached retina, but no coagulation effects were observed in the choroid. Krypton laser beam could go through the hemorrhage and certain coagulation effects were observed in the choroid and the detached retina. It is suggested that krypton laser photocoagulation is more effective in the lesions behind subretinal hemorrhages than photocoagulation with argon laser.
以往的研究表明，氪激光光凝治疗黄斑疾病比氩激光更有效。此外，由于氪激光束不易被血红蛋白吸收，它能在一些伴有视网膜下出血的病变中更有效地进行光凝。在本实验中，用调Q Nd-YAG激光在猴眼中造成出血性视网膜脱离，4周后用氪激光和氩激光进行光凝，以比较这两种激光效果的差异。当在脱离的视网膜中产生视网膜下出血和重度凝固效应时，在脉络膜中未观察到凝固效应。氪激光束可穿透出血，并在脉络膜和脱离的视网膜中观察到一定的凝固效应。提示氪激光光凝在视网膜下出血后的病变中比氩激光光凝更有效。
