OIS, ocular ischemic syndrome; DR, diabetic retinopathy; HM, high myopia; OCT, optical coherence tomography; FFA, fundus fluorescein angiography; ARCT, arm-retinal circulation time; RCT, retinal circulation time; SD, standard deviation.
p-values for comparisons among OIS, DR, and HM.
p < 0.05 was considered statistically significant.
