To evaluate intraocular pressure (IOP) and extraocular orbital vessels with color Doppler ultrasound (CDU) and investigate the effects of obesity on retrobulbar blood flow.
Fifty-nine patients were included in this prospective study. Patients were divided into two groups according to body mass index: Group 1 (31 obese patients) and Group 2 (28 non-obese patients). IOP was measured with a Goldmann applanation tonometer, and CDU was used to evaluate the retrobulbar vessels.
The mean IOP was 18 ± 6.68 mmHg in the obese group and 13.71 ± 1.60 mmHg in the control group (p<0.001). When the CDU values for the central retinal artery were compared between the groups, the pulsatility index was found to be significantly lower in the obese group than in the control group (p<0.001). When the CDU values for the ophthalmic artery (OA) were compared between the groups, the peak systolic velocity (p<0.001) and end-diastolic velocity (p=0.002) values were found to be significantly lower in the obese group than in the control group.
Obese patients have a higher mean IOP and lower flow velocity than non-obese patients. Increased IOP together with decreased retrobulbar blood flow, particularly in obese individuals, may increase the risk of glaucoma development.
使用彩色多普勒超声（CDU）评估眼压（IOP）和眼外眶血管，并研究肥胖对球后血流的影响。
59例患者纳入本前瞻性研究。根据体重指数将患者分为两组：第1组（31例肥胖患者）和第2组（28例非肥胖患者）。使用Goldmann压平眼压计测量眼压，并用CDU评估球后血管。
肥胖组平均眼压为18±6.68 mmHg，对照组为13.71±1.60 mmHg（p<0.001）。比较两组视网膜中央动脉的CDU值时，发现肥胖组的搏动指数显著低于对照组（p<0.001）。比较两组眼动脉（OA）的CDU值时，发现肥胖组的收缩期峰值速度（p<0.001）和舒张末期速度（p=0.002）值显著低于对照组。
肥胖患者比非肥胖患者平均眼压更高，血流速度更低。眼压升高以及球后血流减少，尤其是在肥胖个体中，可能会增加青光眼发生的风险。
