To report the use of photodynamic therapy (PDT) for choroidal neovascularization (CNV) in pediatric patients.
Five patients (age range, 7-15 years) who underwent PDT for idiopathic CNV (n = 2) or CNV secondary to macular toxoplasmic scar (n = 3) were included in this study. Follow-up ranged from 12 months to 18 months. PDT was performed according to the standard protocol. We evaluated visual acuity, fluorescein leakage from the CNV, greatest linear dimension of the lesion, and occurrence of ocular or systemic adverse events at baseline and during follow-up.
No severe or moderate visual loss occurred in all cases during follow-up. PDT reduced CNV leakage in four cases. No serious ocular or systemic adverse events were recorded. Retinal pigment epithelium atrophic changes were observed around the regressed CNV, but they did not appear to cause visual loss.
PDT was safe for pediatric patients, and visual acuity was substantially stable after one or few treatments. Further follow-up is needed to assess if retinal pigment epithelium atrophic changes around the regressed CNV, possibly related to PDT, could affect vision in the long term.
报告光动力疗法(PDT)在儿科患者脉络膜新生血管(CNV)治疗中的应用。
本研究纳入5例接受PDT治疗的患者(年龄范围7 - 15岁),其中特发性CNV患者2例,黄斑部弓形虫瘢痕继发CNV患者3例。随访时间为12个月至18个月。PDT按照标准方案进行。我们在基线及随访期间评估了视力、CNV的荧光素渗漏、病变的最大线性尺寸以及眼部或全身不良事件的发生情况。
随访期间所有病例均未发生严重或中度视力丧失。PDT使4例患者的CNV渗漏减少。未记录到严重的眼部或全身不良事件。在消退的CNV周围观察到视网膜色素上皮萎缩性改变,但它们似乎未导致视力丧失。
PDT对儿科患者是安全的,经过一次或几次治疗后视力基本稳定。需要进一步随访以评估消退的CNV周围可能与PDT相关的视网膜色素上皮萎缩性改变是否会长期影响视力。
