To compare 12-month results of two single initial treatments--photodynamic therapy with verteporfin alone (PDT group), and this therapy combined with intravitreal bevacizumab (IVB) (COMB group)--for neovascular age-related macular degeneration (AMD), not including patients with polypoidal choroidal vasculopathy (PCV) who were presumed to have AMD.
This retrospective study evaluated 23 eyes in the PDT group and 22 eyes in the COMB group. IVB (1.25 mg) was administered within 2 weeks after PDT. Main outcome measures were best-corrected visual acuity (VA), central foveal thickness by optical coherence tomography, and number of treatments.
At month 12, the PDT group had gained 0.7 letter mean VA and the COMB group, 8.8 letters (P = 0.04). Ten eyes (43%) in the PDT group and 19 eyes (86%) in the COMB group received only one treatment, and significant difference was found (P = 0.005). No severe ocular or systemic safety concerns were discovered.
Our 12-month results of PDT combined with IVB for Japanese patients with AMD without PCV appeared to be more effective than those of PDT alone with fewer treatments.
比较两种单一初始治疗方法——单纯光动力疗法(PDT 组)和该疗法联合玻璃体内贝伐单抗(IVB)(COMB 组)——治疗新生血管性年龄相关性黄斑变性(AMD)的 12 个月结果,不包括假定患有 AMD 的息肉样脉络膜血管病变(PCV)患者。
这项回顾性研究评估了 PDT 组的 23 只眼和 COMB 组的 22 只眼。PDT 后 2 周内给予 IVB(1.25mg)。主要观察指标为最佳矫正视力(VA)、光学相干断层扫描的中心黄斑厚度和治疗次数。
在 12 个月时,PDT 组平均 VA 提高了 0.7 个字母,COMB 组提高了 8.8 个字母(P=0.04)。PDT 组有 10 只眼(43%)和 COMB 组有 19 只眼(86%)仅接受了一次治疗,差异有统计学意义(P=0.005)。未发现严重的眼部或全身安全性问题。
我们的 12 个月结果表明,对于没有 PCV 的日本 AMD 患者,PDT 联合 IVB 的治疗效果似乎优于单纯 PDT,且治疗次数更少。
