Abstract

The panretinal photocoagulation(PRP) is known to increase the absorption of fluid through the retinal pigment epithelium by destroying blood retinal barrier. Therefore we thought that PRP could increase vitreoretinal choroidal outflow in vitreous hemorrhage. In order to investigate the effect of PRP on the absorption of vitreous hemorrhage, we performed animal experiment with 12 rabbits divided into 4 groups, and the results were as follows; 1) In phakic eyes, the vitreous hemorrhage was absorbed faster in group with PRP than in group without PRP(p<0.05). 2) The vitreous hemorrhage was absorbed faster in aphakic eyes than in phakic eyes(p<0.05). 3) In aphakic eyes, the vitreous hemorrhage was absorbed faster in group with PRP than in group without PRP, but it was not statistically significant(p>0.05).
