UNLABELLED: Central serous chorioretinopathy (CSCR) can be complicated by different types of choroidal neovascularization (CNV). The purpose of this study was to investigate the incidence and quantitative optical coherence tomography angiography (OCT-A) features of CSCR-related CNVs. METHODS: This was a retrospective multicenter study including 102 eyes of 102 Caucasian patients with acute or complex CSCR. All patients underwent a comprehensive ophthalmological examination. Quantitative OCT-A parameters, including vascular perfusion density (VPD), fractal dimension (FD), and lacunarity (LAC), were measured in CNV eyes. RESULTS: Forty eyes (39.2%) had acute CSCR, whereas the remaining sixty-two (60.8%) had complex CSCR. CNV was observed in 37 (36.27%) eyes, all of which had the complex form. CNVs were classified as type 1 CNV in 11/37 (29.73%) cases and as polypoidal choroidal vasculopathy (PCV) in the remaining 26/37 (70.27%). Overall, the mean VPD, FD, and LAC of CSCR-related CNVs were 0.52 ± 0.20%, 1.44 ± 0.12, and 2.40 ± 1.1, respectively. No significant difference between type 1 CNV and PCV was found. CONCLUSION: Complex CSCR is often complicated by type 1 CNV and PCV with similar neovascular architecture and branching complexity, a finding supporting the idea that they might be different stages of the same neovascular process. Future OCT-A fractal analysis-based studies that also include other relevant parameters, such as demographics, presentation, morphology on multimodal imaging, and response to treatment, are necessary before drawing any definitive conclusions.
未标注:中心性浆液性脉络膜视网膜病变(CSCR)可并发不同类型的脉络膜新生血管(CNV)。本研究的目的是调查CSCR相关CNV的发生率及定量光学相干断层扫描血管造影(OCT-A)特征。 方法:这是一项回顾性多中心研究,纳入102例患有急性或复杂性CSCR的白种人患者的102只眼。所有患者均接受了全面的眼科检查。对CNV眼测量定量OCT-A参数,包括血管灌注密度(VPD)、分形维数(FD)和孔隙率(LAC)。 结果:40只眼(39.2%)患有急性CSCR,其余62只眼(60.8%)患有复杂性CSCR。在37只眼(36.27%)中观察到CNV,所有这些眼均为复杂性形式。在37例中的11例(29.73%)中CNV被分类为1型CNV,其余26例(70.27%)被分类为息肉样脉络膜血管病变(PCV)。总体而言,CSCR相关CNV的平均VPD、FD和LAC分别为0.52±0.20%、1.44±0.12和2.40±1.1。1型CNV和PCV之间未发现显著差异。 结论:复杂性CSCR常并发1型CNV和PCV,具有相似的新生血管结构和分支复杂性,这一发现支持它们可能是同一新生血管过程不同阶段的观点。在得出任何明确结论之前,有必要进行基于OCT-A分形分析的进一步研究,这些研究还应包括其他相关参数,如人口统计学、表现、多模态成像的形态学以及对治疗的反应。
