经瞳孔温热疗法治疗中心性渗出性脉络膜视网膜炎的疗效观察

目的 探讨经瞳孔温热疗法(traspupillary thermotherapy, TTT)治疗中心性渗出性脉络膜视网膜炎(central exudative chorioretinopathy,CEC)的临床效果。 方法 对荧光素眼底血管造影(fundus fluorescein angiography,FFA)和吲哚青绿血管造影(indocyanine green angiography,ICGA)检查确诊的CEC患者的12只患眼进行TTT治疗。采用810 nm半导体激光，光斑0.5～2.0 mm，照射时间55～60 s，能量200～350 mW，对 FFA和ICGA图像所显示的脉络膜新生血管(choroidal neovascularization,CNV)进行照射，照射区未出现颜色变化或呈淡灰色。对比分析患者治疗前后的视力、眼底、FFA和ICGA检查结果。 结果 TTT治疗后0.5～3个月后所有患眼视力都有不同程度提高，视力提高5行以上者4只眼，占33.3%；3～5行者 5只眼，占41.7%；1～2行者 3只眼，占25.0%。治疗后10只眼行FFA和ICGA复查，其中FFA复查荧光素渗漏消失7只眼，减轻3只眼；ICGA复查CNV消失或明显缩小8只眼，CNV无变化2只眼。 结论 TTT治疗CEC效果良好，值得临床推广应用。 (中华眼底病杂志, 2002, 18: 187-189)

Transpupillary thermotherapy of central exudative chorioretinopathy

Objective To evaluate the effects of traspupillary thermotherapy (TTT) for the treatment of central exudative chorioretinopathy (CEC). Methods Twelve eyes of 12 patients who suffered from CEC were treated by using a diode laser at 810 nm. A variable spot size of 0.5 mm 2 0 mm was used depending on the size of choroidal neovascularization (CNV).The treatment was initiated in one spot for 55 to 60 seconds duration at a power range between 200 350 mW, and the treated area revealed no visible color change to a light gray appearance. Preoperative and postoperative fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were performed in 10 of the 12 eyes. Results The visual acuity in all eyes was improved to different degree over a period of 3 10 months. Five or more lines improvement measured by Snellen chart in visual acuity was found after the treatment in 4 eyes, three to five lines in 5 eyes and one to two lines in 3 eyes. All eyes demonstrated decreased or vanished exudation in FFA. CNV disappeared or decreaced in 8 eyes and remained nochange in 2 eyes in ICGA. Conclusion TTT is obviously effective in treating CEC.
