The aim was to determine the relationship between bulbar conjunctival microcirculation and retinal microcirculation in a healthy population.
A functional slit-lamp biomicroscope (FSLB) was used to measure blood flow velocity (BFV) and blood flow rate (BFR) in the conjunctiva while a retinal function imager (RFI) was used to measure macular BFV and BFR in the retina. One eye of each subject of 58 self-reported healthy subjects was imaged in the same session on the same day.
The mean BFV in the venules of the conjunctiva was 0.49 ± 0.13 mm/s, which was significantly slower than that in the retinal arterioles (3.71 ± 0.78 mm/s, < 0.001) and retinal venules (2.98 ± 0.58 mm/s, < 0.001). The BFR in the conjunctiva (0.09 nl/s) was also significantly lower than that in the retina (arterioles = 0.81 nl/s, venules = 0.68 nl/s, all < 0.001). The BFVs and BFRs were not related between the conjunctiva and retina (r ranged from - 0.17 to - 0.05, all > 0.05).
The microcirculation in the retina appeared to be different from that in the conjunctiva.
目的是确定健康人群中球结膜微循环与视网膜微循环之间的关系。
使用功能性裂隙灯生物显微镜（FSLB）测量结膜中的血流速度（BFV）和血流量（BFR），同时使用视网膜功能成像仪（RFI）测量视网膜中黄斑的BFV和BFR。在同一天的同一时段对58名自我报告健康的受试者的一只眼睛进行成像。
结膜小静脉中的平均BFV为0.49±0.13mm/s，明显慢于视网膜小动脉（3.71±0.78mm/s，<0.001）和视网膜小静脉（2.98±0.58mm/s，<0.001）中的BFV。结膜中的BFR（0.09nl/s）也明显低于视网膜中的BFR（小动脉=0.81nl/s，小静脉=0.68nl/s，均<0.001）。结膜和视网膜之间的BFV和BFR不相关（r范围为-0.17至-0.05，均>0.05）。
视网膜中的微循环似乎与结膜中的不同。
