To evaluate the efficacy of photodynamic therapy with verteporfin with intravitreal bevacizumab for polypoidal choroidal vasculopathy.
Retrospective case study.
This study included 29 treatment-naïve patients with polypoidal choroidal vasculopathy followed up for 12 months after the first combined therapy. Patients received 1.25 mg intravitreal bevacizumab 1 week before photodynamic therapy with verteporfin. The main outcomes measures were visual acuity and the number of required retreatments.
The mean best-corrected visual acuity (BCVA) level was 0.25 at baseline and 0.31, 0.39, 0.44, 0.44, and 0.45 at 1, 3, 6, 9, and 12 months after treatment, respectively. A significant (P< .01) improvement in the mean BCVA was observed at 3, 6, 9, and 12 months after combined therapy. At 12 months, the mean improvement in BCVA from baseline was 2.69 lines; the BCVA improved in 15 eyes (51.7%) by 3 lines or more, was stable in 13 eyes (44.8%), and decreased in 1 eye (3%) because of a massive subretinal hemorrhage 7 months after the first treatment. Eighteen eyes (62%) required 1 combined treatment during follow-up. Polypoidal lesions recurred in 6 eyes (21%). An abnormal branching vascular network persisted in all eyes. The mean number of treatments with combined therapy averaged 1.59. No complications, including endophthalmitis, uveitis, or ocular hypertension, developed.
Combined treatment consisting of photodynamic therapy with verteporfin and intravitreal bevacizumab for polypoidal choroidal vasculopathy seemed to be effective for improving visual acuity and reducing retreatment rates and complications. Further study is needed to determine the long-term clinical results.
评估光动力疗法联合玻璃体内贝伐单抗治疗息肉状脉络膜血管病变的疗效。
回顾性病例研究。
本研究纳入了 29 例未经治疗的息肉状脉络膜血管病变患者,在首次联合治疗后随访 12 个月。患者在光动力疗法联合玻璃体内贝伐单抗前 1 周接受 1.25mg 玻璃体内贝伐单抗治疗。主要观察指标是视力和所需的再治疗次数。
平均最佳矫正视力(BCVA)水平在基线时为 0.25,分别在治疗后 1、3、6、9 和 12 个月时为 0.31、0.39、0.44、0.44 和 0.45。在联合治疗后 3、6、9 和 12 个月时,平均 BCVA 显著提高(P<.01)。在 12 个月时,从基线开始平均 BCVA 改善了 2.69 行;15 只眼(51.7%)视力提高了 3 行或以上,13 只眼(44.8%)视力稳定,1 只眼(3%)因首次治疗后 7 个月发生大量视网膜下出血而下降。在随访期间,18 只眼(62%)需要 1 次联合治疗。6 只眼(21%)出现息肉状病变复发。所有眼均存在异常分支血管网络。平均联合治疗次数为 1.59 次。未发生眼内炎、葡萄膜炎或眼内高压等并发症。
光动力疗法联合玻璃体内贝伐单抗治疗息肉状脉络膜血管病变似乎可以有效提高视力,降低再治疗率和并发症发生率。需要进一步研究来确定长期的临床效果。
