Transpupillary thermotherapy in the treatment of retinal arterial macroaneurysms

摘要:

目的:观察经瞳孔温热疗法(transpupillary thermotherapy,TTT)治疗视网膜大动脉瘤的疗效。方法:回顾分析24例24眼视网膜大动脉瘤患者行TTT治疗的临床疗效。根据荧光血管造影显示的瘤体大小选择不同的光斑(0.8~1.2mm)和总能量(22.4~36.8mJ),照射时间1min。观察视力、瘤体及管壁恢复情况。结果:所有患者1次治疗后动脉瘤均萎缩,管壁恢复正常,17例视力有提高。结论:TTT是治疗视网膜大动脉瘤的有效方法,尤其适用于伴明显视网膜出血、水肿的患者。

Abstract:

AIM: To evaluate the clinical effect of transpupillary thermotherapy(TTT) in the treatment of retinal arterial macroaneurysms. METHODS: The clinical data of 24 patients 24 eyes with retinal arterial macroaneurysms treated with TTT were retrospectively analyzed. According to the size of neoplasia showed by fundus fluorescein angiography(FFA), diffenent laser spot (0.8-1.2mm) and power (22.4-36.8mJ) were selected. The visual acuity,neoplasia and tube wall instauration were observed. RESULTS: All the neoplasias were atrophied after TTT, and the wall instauration returned to normal. Central vision was increased in 17 eyes. CONCLUSION: TTT is an effective method to treat retinal arterial macroaneurysms, particularly to patients with bleeding and edema.
