4125 Evaluation of frequency doubled ND-YAG versus krypton red laser for photocoagulation of extra foveal and juxta foveal chroidal neovascularization due to age related maculopathy (A.M.D.)

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).
