To describe a new treatment for vision loss caused by subretinal fluid associated with circumscribed choroidal hemangioma.
Three patients were treated with photodynamic therapy using verteporfin for injection (Visudyne; QLT Phototherapeutics Inc, Vancouver, British Columbia). All patients had pretreatment and posttreatment fluorescein angiography and ultrasonography. Treatment parameters used were verteporfin, 6 mg/m(2), and laser light at 689 nm delivered at 50 J/cm(2) with an intensity of 600 mW/cm(2) for 83 seconds.
All patients had complete resolution of subretinal fluid within 2 weeks of treatment. Fluorescein angiography performed 2 to 4 weeks after treatment showed absence of tumor leakage. All eyes had reduced tumor thickness or complete flattening. Visual acuity was improved in each eye. Average follow-up was 5.3 months. No complications were noted.
Photodynamic therapy with verteporfin is effective in eliminating subretinal fluid and improving vision in patients with circumscribed choroidal hemangioma.
描述一种治疗局限性脉络膜血管瘤相关的视网膜下液导致的视力丧失的新方法。
3例患者接受了使用注射用维替泊芬(Visudyne;QLT光治疗公司,加拿大不列颠哥伦比亚省温哥华)的光动力疗法。所有患者在治疗前和治疗后均进行了荧光素血管造影和超声检查。所使用的治疗参数为:维替泊芬6mg/m²,689nm激光,以600mW/cm²的强度在50J/cm²下照射83秒。
所有患者在治疗后2周内视网膜下液完全消退。治疗后2至4周进行的荧光素血管造影显示肿瘤无渗漏。所有患眼的肿瘤厚度均减小或完全变平。每只患眼的视力均有提高。平均随访时间为5.3个月。未观察到并发症。
维替泊芬光动力疗法在消除局限性脉络膜血管瘤患者的视网膜下液和改善视力方面有效。
