摘要/Abstract

摘要： 本文探究光学相干断层扫描血管成像技术（OCTA）在白内障术后黄斑微循环变化中的应用价值。选取我院白内障患者60例（60眼），根据术后1个月最佳矫正视力（BCVA）分为不良组与良好组。手术前后均行OCTA检查，良好组术后1个月黄斑区全层和内层平均视网膜厚度、黄斑中心凹周边DCP高于术前，黄斑FAZ面积小于术前，不良组术前、术后1个月黄斑区全层、内层平均视网膜厚度低于良好组，黄斑FAZ面积大于良好组，术后1个月黄斑中心凹周边DCP低于良好组（P<0.05）；术前黄斑区全层、内层平均视网膜厚度与BCVA呈正相关，黄斑FAZ面积与BCVA呈负相关，术前、术后1个月黄斑区全层和内层平均视网膜厚度、黄斑FAZ面积，以及术后1个月黄斑中心凹周边DCP与术后视力恢复不良显著相关（P<0.05）。提示OCTA所测黄斑微循环参数对白内障患者术后BCVA具有良好评估作用。

Abstract: This paper exploresd the application value of optical coherence tomography angiography (OCTA) in the changes of macular microcirculation after cataract surgery. Sixty cases (60 eyes) of cataract patients in our hospital were divided into poor group and good group according to the best corrected visual acuity (BCVA) one month after operation. OCTA was performed before and after the operation. In the good group, the full-thickness and inner-layer average retinal thickness and DCP around the macular fovea were higher than those before the operation, and the macular FAZ area was smaller than that before the operation. In the bad group, the full-thickness and inner-layer average retinal thickness of the macular area was lower than that in the good group, and the macular FAZ area was larger than that in the good group, one month after operation, DCP around macular fovea was lower than that in good group (P<0.05). The mean retinal thickness of the whole and inner layers of the macular region before operation was positively correlated with BCVA, and the macular FAZ area was negatively correlated with BCVA. The mean retinal thickness of the whole and inner layers of the macular region before operation and 1 month after operation, the macular FAZ area, and the peripheral DCP of the macular fovea one month after operation were significantly correlated with poor postoperative visual recovery (P<0.05). It is suggested that the parameters of macular microcirculation measured by OCTA have a good evaluation effect on BCVA after cataract surgery.
