Panretinal cryoablation was performed on 100 eyes with retinal neovascularization and vitreous hemorrhage. Of those 100 eyes, 70 had neovascularization and recurrent hemorrhage despite previous panretinal laser photocoagulation, and 30 eyes had media opacities precluding laser treatment. Sixty applications, random and focal, were placed in each eye. Forty-six percent of eyes achieved better visual acuity, 32% were unchanged, and 22% were worse. Eighty-three percent of eyes had vision of 20/200 or better. In eyes without prior laser photocoagulation, 83% were clear of vitreous hemorrhage following cryoablation, and in eyes with previous panretinal photocoagulation, 75% were free of vitreous hemorrhage after cryoablation.
对100只患有视网膜新生血管和玻璃体出血的眼睛进行了全视网膜冷冻治疗。在这100只眼中，70只尽管先前进行了全视网膜激光光凝仍有新生血管和反复出血，30只眼因介质混浊无法进行激光治疗。每只眼睛随机进行60次局灶性冷冻治疗。46%的眼睛视力提高，32%不变，22%变差。83%的眼睛视力达到20/200或更好。在未进行过激光光凝的眼睛中，83%在冷冻治疗后玻璃体出血清除，在先前进行过全视网膜光凝的眼睛中，75%在冷冻治疗后无玻璃体出血。
