光学相干断层扫描血流成像对特发性息肉样脉络膜血管病变患者的分析研究

Analysis and research of patients with idiopathic polypoidal choroidal vasculopathy by optical coherence tomography angiography

目的研究光学相干断层扫描血流成像(OCTA)对特发性息肉样脉络膜血管病变(PCV)患者的眼底情况分析。方法选取2018年6—12月已经金标准眼底吲哚青绿血管造影(ICGA)确诊的PCV患者50眼作为研究对象,行OCTA检查,观察患者的检查结果。结果患眼经OCTA检查,其中48眼能发现脉络膜分支血管网(BVN),阳性率为96.0%;发现息肉样病灶(polyps)25只眼,阳性率为50.00%。结论光学相干断层扫描血流成像在息肉样脉络膜血管病变患者检查中都具有一定优越性,可直观、清晰显示视网膜内外层的细微结构,检查过程便捷无创,利于诊断及治疗,值得推广。

Objective To research the fundus analysis of patients with idiopathic polypoidal choroidal vasculopathy(PCV) by optical coherence tomography angiography(OCTA). Methods A total of 50 eyes of patients with PCV who have been diagnosed by indocyanine green angiography(ICGA), which was the gold standard, from June to December 2018 as research objects. OCTA examinations were performed, of which the results of patients were observed. Results The results of OCTA examination showed that branching vascular network(BVN) was found in 48 eyes, and the positive rate was 96.0%. Polyps were found in 25 eyes, and the positive rate was 50.00%. Conclusion OCTA has certain advantages in the examination of patients with PCV. It can visually and clearly show the fine structure of the inner and outer layers of retina. The examination process is convenient and non-invasive, which is conducive to diagnosis and treatment, and is worthy of promotion.
