Abstract

Purpose: To analyze features of the choriocapillaris in fellow eyes with thick and thin polypoidal choroidal vasculopathy (PCV).

Methods: We retrospectively reviewed optical coherence tomography (OCT) and OCT-angiography in the fellow eyes of patients with unilateral PCV. Patients were categorized into thick and thin PCV groups based on a subfoveal choroidal thickness of 250 μm. The choriocapillaris characteristics of the fellow eyes were compared with the controls.

Results: We classified 59, 53, and 63 patients into thick PCV, thin PCV, and control groups, respectively. No difference was found in the total number of flow voids among the three groups. The total flow void (FV) density (%) differed among the thick PCV group (25.64±8.57), thin PCV group (29.72±7.61), and control group (30.35±6.78) (P < 0.001). The number and density of large-sized (>400 μm2) FVs also differed among the thick PCV group (2177.63±887.10, 20.49±11.31%), thin PCV group (2605.92±806.05, 25.58±10.48%), and control group (2807.14±789.49, 25.93±9.38%) (P < 0.001, 0.006).

Conclusion: In PCV, the FV characteristics of the choriocapillaris in the fellow eyes differed between the thick and thin PCV groups. This finding suggests that the conditions of the choroid and choriocapillaris may vary between thick and thin PCV.

厚、薄息肉样脉络膜血管病变伴眼的绒毛膜毛细血管病变。

目的：分析厚、薄息肉样脉络膜血管病变（PCV）伴眼脉络膜毛细血管的特点。方法：回顾性分析单侧PCV患者的同侧眼光学相干断层扫描（OCT）和OCT血管造影。以250 μm的中央凹下脉络膜厚度为标准，将患者分为厚、薄两组。与对照组比较各组眼的绒毛膜毛细血管特征。结果：我们将59例、53例和63例患者分别分为厚PCV组、薄PCV组和对照组。三组间的总流道数无差异。厚PCV组（25.64±8.57）、薄PCV组（29.72±7.61）、对照组（30.35±6.78）的总流动空隙密度（%）差异有统计学意义（P < 0.001）。厚PCV组（2177.63±887.10,20.49±11.31%）、薄PCV组（2605.92±806.05,25.58±10.48%）、对照组（2807.14±789.49,25.93±9.38%）的大尺寸FVs （bb0 400 μm2）数量和密度差异均有统计学意义（P < 0.001, 0.006）。结论：厚、薄两组PCV伴眼绒毛膜毛细血管的FV特征不同。这一发现提示脉络膜和绒毛膜毛细血管的状况可能在厚和薄的PCV之间有所不同。
