4128 Immunoelectron microscopic evaluation of the microvasculature in subretinal neovascular membranes

m. Krypton laser photocoagulat on has been demonstrated to be efficient in the treatment of juxtafoveal well-defined choroidal new vessels in AMD. The efficacy of two different wavelengths frequency doubled Nd-Yag Laser (FDYL) and krypton red (KR) was compared in the treatment of extrafoveal and juxtafoveal well-defined choroidal neovascularization (CNV) secondary to A.M.D. &$,&Q&. 38 eyes were randomly assigned to frequency doubled Yeg (I8 eyes) or krypton red laser (20 eyes). The judgment criteria were the followings : 1) persistence or recurrence rate at I month after laser treatment, 2) final visual acuity, 3) CNV size (< l/4 DD ; lWl12DD : > l/2 DD) and 4) location to the fovea (< SO p ; 50.400 p , > 400 I*). Beyllts. The rate of persistence or recurrence was comparable between FDYL (33,3%) and krypton (30%) groups (p < 0.5).
