摘　　要：目的 :观察用氪红激光大光斑、低能量、长时间照射眼底视网膜下新生血管 (SRNV )及脉络膜血管瘤的治疗效果。方法 :选用经临床眼底检查、FFA检查 (部分作ICG检查 )证实的视网膜下新生血管病例 2 0例 ,其中渗出型增龄性黄斑变性(AMD) 14例 ,高度近视黄斑出血 4例 ,中心性渗出性视网膜脉络膜病变 (中渗 ) 2例 ;另有 2例孤立性脉络膜血管瘤。使用氪红激光经瞳孔照射病灶部位。所用激光参数为 ,光斑直径 75 0～ 10 0 0 μm、功率 75～ 10 0mW、照射时间 2 0～ 3 0S ,根据病灶范围大小确定激光点数 ,RNV激射 1～ 6点 ,平均 3点 ,脉络膜血管瘤激射 2 0～ 46点不等。术后复查视力、眼底检查、FFA (及ICG)检查 ,评价治疗效果。结果 :2 2例中有随访记录的 18例 ,随访 12例AMD中治愈 7例 ,好转 4例 ,视力下降 1例 ;中渗 2例中治愈 1例 ,好转 1例 ;高度近视 2例中治愈 1例 ,好转 1例 ;2例脉络膜血管瘤均获治愈。结论 :使用大光斑、低能量、长时间氪红激光治疗视网膜下新生血管病变及脉络膜血管瘤 ,对新生血管的萎缩、保存和恢复视力疗效可靠 ,副作用小。Objective:To investigate the effects on subretinal neovascularization (SRNV) and uveal aneurysms (UA) of Krypton red laser with larger spots,lower energy and longer laser time. Methods:22 cases of SRNV and UA,including 14 cases of exudative age-related macular degeneration ,4 cases of high myopia,2 cases of central exudative chorioretionitis and 2 cases of single uveal aneurysms were involved.Laser parameters were as follows:spot diameter 750～1000μm,power 75～100mW,time 20～30s.Laser spots and parameters were adjusted according to the range of SRNV and UA.The effects of Kr-red laser were evaluated by vision,ocular examination,FFA and ICG. Results:Follow up was collected completely in 18 cases,including 12 cases of exudative AMD with 7 case SRNV disappeared and 4 cases abated as well as 1 case vision recessed,2 cases of high myopia with 1 case SRNV disappeared and the other abated,2 UA cases with totally disappeared SRNV. Conclusions:Kr-red laser with larger spots and lower energy as well as longer time can effectively suppress SRNV and UA,and was with less side effects.
