There are few reports evaluating the treatment of pachychoroid neovasculopathy (PNV) in white patients. The purpose of this study is to analyze the results of a treat and extend regimen with aflibercept in white patients with PNV after 2 years of follow-up.
We performed a retrospective study in 31 eyes of 26 patients with PNV treated with a treat an extend regimen of intravitreal aflibercept. The mean age was 63,84 ± 7.92 years. There were 9 males (35%) and 17 females (65%). Best-corrected visual acuity (BCVA), central macular thickness (CMT), choroidal subfoveal thickness (CST), choroidal thickness (CT) under type 1 choroidal neovascularization (CNV), pigment epithelium detachment (PED) height, and presence of subretinal fluid (SRF), intraretinal fluid (IRF) and wet macula, were evaluated at baseline and after 3, 6, 12, and 24 months.
BCVA remained stable during the follow-up ( 0.161). A significant diminution of CMT was found ( 0.001). Conversely, PED height diminution was not significative ( 0.260). CST and CT under type 1 CNV improved significantly during the follow-up ( 0.005 and 0.009, respectively). Also, wet macula improved after 24 months ( < .001). The average number of intravitreal injections was 12.34 ± 6.01.
Treat and extend regimen with intravitreal aflibercept in white patients with PNV may be effective for improving CMT, CST, CT under type 1 CNV and wet macula, and to stabilize vision, with a personalized regimen of intravitreal injections.
针对白种人患发性脉络膜新生血管(pachychoroid neovasculopathy,PNV)的治疗方法,相关报告较少。本研究旨在分析白种人患 PNV 后,采用阿柏西普玻璃体腔内注射治疗及扩展方案治疗 2 年的结果。
我们对 31 只眼 26 例 PNV 患者进行了回顾性研究,这些患者均采用玻璃体腔内注射阿柏西普的治疗及扩展方案进行治疗。患者平均年龄为 63.84±7.92 岁,其中男性 9 例(35%),女性 17 例(65%)。最佳矫正视力(BCVA)、中心黄斑厚度(CMT)、脉络膜下黄斑厚度(CST)、1 型脉络膜新生血管(CNV)下脉络膜厚度(CT)、色素上皮脱离(PED)高度、以及视网膜下液(SRF)、视网膜内液(IRF)和湿性黄斑的存在情况,在基线时和治疗后 3、6、12 和 24 个月进行评估。
BCVA 在随访期间保持稳定(0.161)。CMT 显著降低(0.001)。相反,PED 高度降低不显著(0.260)。CST 和 1 型 CNV 下 CT 在随访期间显著改善(分别为 0.005 和 0.009)。24 个月后湿性黄斑也得到改善( < 0.001)。平均玻璃体腔内注射次数为 12.34±6.01 次。
对于白种人 PNV 患者,采用玻璃体腔内注射阿柏西普的治疗及扩展方案可能是一种有效的治疗方法,可改善 CMT、CST、1 型 CNV 下 CT 和湿性黄斑,并通过个性化的玻璃体腔内注射方案稳定视力。
