摘要： 目的检测眼压变化对白内障手术视盘、黄斑的灌注密度、血管密度的影响。方法选取2016年1月至2019年1月进行白内障超声乳化吸除结合人工晶状体植入患者100例(100眼),依据患者不同水平将患者分成4组,其中眼压<21 mmHg 38例、21~30 mmHg 15例、31~40 mmHg 19例、>40 mmHg 28例,观察患者手术前、术后即刻,术后1 h、8 h、24 h患者眼压、黄斑与视盘血管密度、灌注密度情况。结果术后即刻、术后1 h患者黄斑、视盘灌注密度较术前降低;眼压>40 mmHg组患者术后8 h黄斑与视盘血管密度较术前降低,>40 mmHg组患者术后24 h黄斑与视盘血管密度、视盘灌注密度较术前降低;31~40 mmHg、>40 mmHg组患者术后24 h黄斑灌注密度较术前降低。结论白内障手术患者术中灌注压会造成视盘与黄斑灌注密度、血管密度下降,在术后60 min其血管密度可恢复至正常水平,同时患者术后眼底血流密度会受到眼压波动的影响。

Abstract: Objective To analyze the effect of intraocular pressure fluctuations on vascular density in patients who undergo cataract surgery. Methods One hundred patients(100 eyes)who underwent phacoemulsification and intraocular lens implantation at our hospital between January 2016 and January 2019 were enrolled. The patients were divided into 4 groups according to their intraocular pressure levels as follows: 38 patients were in the <21 mmHg group, 15 patients the 21-30 mmHg group, 19 patients in the 31-40 mmHg group, and 28 patients were in the >40 mmHg group. The patients underwent an intraocular pressure and macular spot test before and after surgery, as well as 60 minutes, 8 hours, and 24 hours after the operation. Optic disc vascular density and perfusion density were also determined. Results Immediately after the surgery and 1-hour following, the macular and optic disc perfusion density were lower than before the operation. In the >40 mmHg group, the intraocular pressure was lower than the preoperative blood density 8 hours after surgery. The macular density and optic disc perfusion density were lower than before the operation after 24 hours in the >40 mmHg group. The macular perfusion density of patients in the 31-40 mmHg and >40 mmHg groups was lower than before the operation. Conclusion Intraoperative perfusion pressure in cataract surgery can cause optic disc macular perfusion density and vascular density to decrease. Vascular density can be restored to a normal level 60 minutes after the operation. The fundus blood flow density will be affected by intraocular pressure fluctuations.
