Polypoidal choroidal vasculopathy (PCV) is a vascular disease of the choroid that leads to hemorrhagic and exudative macular degeneration. It may cause significant vision loss and thus affect the quality-of-life and psychological well-being. Non-invasive, non-ICGA-based OCT criteria have shown reliable results to plan adjunct photodynamic therapy (PDT) treatment, with the complete and consistent coverage of polypoidal lesions (PL) and branching neovascular network (BNN). The safety and efficacy of anti-vascular endothelial growth factor (anti-VEGF) monotherapy and its combination with verteporfin PDT have been established. However, treatment is still challenging due to frequent follow-ups, non-availability of PDT, and need for multiple anti-VEGF injection visits that increase the treatment burden and lead to patients being lost to follow-up. Effective treatments that prolong intervals between injections while maintaining vision and anatomical gains remain a critical unmet need. Longer acting molecules, like brolucizumab, have shown non-inferiority in BCVA gains and superior anatomical outcomes compared to other anti-VEGF agents. Newer therapies in the pipeline to enhance the efficacy and longevity of treatment include Faricimab and a port delivery system (PDS). This review summarizes the most recent diagnostic and treatment approaches in PCV to offer better treatment avenues.
息肉样脉络膜血管病变(PCV)是一种脉络膜血管疾病,可导致出血性和渗出性黄斑变性。它可能会导致严重的视力丧失,从而影响生活质量和心理健康。基于非侵入性、非吲哚青绿血管造影(ICGA)的光学相干断层扫描(OCT)标准已显示出可靠的结果,可用于规划辅助光动力疗法(PDT)治疗,实现息肉样病变(PL)和分支新生血管网络(BNN)的完全且一致的覆盖。抗血管内皮生长因子(抗VEGF)单药治疗及其与维替泊芬PDT联合治疗的安全性和有效性已得到证实。然而,由于需要频繁随访、无法获得PDT以及需要多次进行抗VEGF注射就诊,增加了治疗负担并导致患者失访,治疗仍然具有挑战性。在维持视力和解剖学改善的同时延长注射间隔的有效治疗方法仍然是一个关键的未满足需求。与其他抗VEGF药物相比,作用时间更长的分子,如布罗利尤单抗,在最佳矫正视力(BCVA)改善方面显示出非劣效性,并且在解剖学结果方面更优。正在研发的提高治疗效果和延长治疗持续时间的新疗法包括法西单抗和一种端口递送系统(PDS)。本综述总结了PCV的最新诊断和治疗方法,以提供更好的治疗途径。
