Five consecutive patients with proliferative diabetic retinopathy who were treated successfully with panretinal photocoagulation subsequently developed a central retinal artery obstruction. Iris neovascularization developed in the affected eye within one to three months after the obstruction in four of the five patients despite the previous laser treatment. Additional retinal ischemia, as occurs in central retinal artery obstruction, appears to promote marked iris neovascularization in a large percentage of patients, even when successful photocoagulation for proliferative retinopathy has been previously administered.
连续5例接受全视网膜光凝治疗成功的增殖性糖尿病视网膜病变患者随后发生了视网膜中央动脉阻塞。5例患者中有4例在阻塞后1至3个月内患眼出现虹膜新生血管，尽管之前进行了激光治疗。视网膜中央动脉阻塞时发生的额外视网膜缺血似乎在很大比例的患者中促进了明显的虹膜新生血管形成，即使之前已成功进行了增殖性视网膜病变的光凝治疗。
