应用眼动脉压计测量视网膜血压有助于诊断衡量颈动脉循环。当眼动脉压计压迫眼球,施加压力使视网膜中央动脉搏动时,眼动脉压计所示的读数即是舒张压;动脉搏动停止时的读数便是收缩压。当两眼舒张压相差15%,收缩压相差20%时,则在压力偏低的一侧显示有颈动脉循环障碍。如两眼压不相等时, Using an ophthalmometer to measure retinal blood pressure helps diagnose carotid artery circulation. When the ophthalmic arterial ophthalmic pressure eye, the pressure applied to the central retinal artery pulse, the ophthalmometer readings shown is diastolic; arterial pulse is the reading when the systolic blood pressure. When the two diastolic pressure difference of 15%, systolic pressure difference of 20%, then the side of the lower pressure shows a carotid circulatory disturbance. If the pressure is not equal between the two eyes,
