目的观察经瞳孔温热疗法(transpupillarythermotherapy,TTT)治疗脉络膜血管瘤的疗效。方法回顾分析12例12眼脉络膜血管瘤患者行TTT治疗的临床疗效,根据瘤体的大小选择不同大小的光斑(1.0～3.0mm)和能量(300～1000mW),照射时间1分钟。观察视力、视网膜下液、瘤体、脉络膜血管渗漏变化和并发症的发生情况。随访12～14月,平均13.6月。结果12例脉络膜血管瘤患者中伴局限性或广泛性渗出性视网膜脱离11例。经TTT治疗后,视网膜下液完全吸收,12例瘤体萎缩,FFA显示瘤体渗漏明显减轻,未见明显并发症。视力提高者9例,不变者2例,下降者1例。结论TTT是治疗脉络膜血管瘤的有效方法,尤其适用于伴明显视网膜脱离的患者。
Objective To observe the effect of transpupillary thermotherapy (TTT) on choroidal hemangiomas. Methods The clinical efficacy of TTT in 12 patients with choroidal hemangioma was retrospectively analyzed. Different sizes of light spot (1.0 ~ 3.0mm) and energy (300 ~ 1000mW) were selected according to the size of the tumor. The irradiation time was 1 minute. Visual acuity, subretinal fluid, tumor, choroidal vascular leakage changes and complications occurred. Follow-up 12 to 14 months, an average of 13.6 months. Results Twelve patients with choroidal hemangiomas had localized or extensive exudative retinal detachment in 11 cases. After TTT treatment, subretinal fluid completely absorbed, 12 cases of tumor atrophy, FFA showed significantly reduced tumor leakage, no significant complications. Visual acuity in 9 cases, unchanged in 2 cases, decreased in 1 case. Conclusion TTT is an effective method for the treatment of choroidal hemangiomas, especially for patients with obvious retinal detachment.
