Abstract

To evaluate the effects of the anterior retinal cryopexy on the absorption of the vitreous hemorrhage. vitreous hemorrhage was induced in 27 rabbit eyes. 0.1ml of autologous venous blood was injected into the vitreous through the sclera 3mm posterior to the corneoscleral limbus with 26 gauze needle. Anterior retinal cryopexy was applied on the sclera anterior to the equator(15 eyes). The treatment consisted of 24 cryopexy applications, applied 360degrees transconjunctivally between the ora serrata and equator. Cryopexy was not applied in the control eyes(12 eyes). The Results were as follows : 1) Vitreous hemorrhage was completely absorbed in 2/12 eyes in the control group. and 8/13 eyes in the treated group during the observation period. 2) There was no statistically significant difference in the period that the vitreous was cleared to Grade I opacity beteween the control and treated groups. 3) Cataract was developed in the 2 eyes of treated group 5 weeks after anterior retinal cryopexy.
