【摘要】 目的:探讨经瞳孔温热疗法(transpupillary thermotherapy,TTT)治疗中心性渗出性脉络膜视网膜病变(central exudative chorioretinopathy,CEC)的临床效果。方法:对眼底荧光素血管造影(fundus fluorescein angiography,FFA)和吲哚青绿血管造影(indo cyanine green angiography,ICGA)检查确诊的CEC患者的18只患眼进行TTT治疗。采用810nm半导体激光,光斑0.8～2.0mm,照射时间60s,能量80～300mW,对FFA和ICGA图像所显示的脉络膜新生血管(choroidal neo vascularization,CNV)进行照射,照射区未出现颜色变化。对比分析患者治疗前后的视力、眼底、FFA结果。结果:治疗后视力提高者6眼,占33%;无变化者12眼,占67%。自觉症状有程度不同的改善者16眼,眼底检查病变减轻者10眼。13眼复查眼底血管造影,其中8眼脉络膜新生血管(choroidalneovascularization,CNV)明显消退、渗漏减轻。结论:TTT治疗CEC效果良好,值得临床推广应用。更多还原

【Abstract】 · AIM:To evaluate the effects of transpupillary thermotherapy(TTT)for the treatment of central exudative chorioretinopathy(CEC).· METHODS:Eighteen eyes of 18 cases suffered from CEC were treated with TTT delivered via diode laser at wavelength 810nm.A variable spot size of 0.8～2.0mm was used depending on the size of choroidal neovascularization(CNV).The treatment was initiated in one spot for 60 seconds,duration at a power range between 200～350mW,and the treated area revealed no visible color.Preoperative and postoperative fluorescein angiography(FFA)was performed in 13 eyes.· RESULTS:The visual acuity improved in 6 eyes(33%)and remained unchanged in 12 eyes(67%).The symptom of self-knowledge was differently enhanced in 16 eyes.The pathological changes alleviated in 10 eyes in fundus examination.Fluorescein angiography(FFA)was performed in 13 eyes.CNV evidently vanished and exudation decreased in 8 eyes and 5 eyes remained unchanged in FFA.· CONCLUSION:TTT is an effective method in treating CEC.·更多还原
