Methods The peak systolic velocity and resistive index of ophthalmic artery were measured by colour doppler and two dimensional echocadiography ( 2 DE) in 48 myopia students with glasses before and after the ocular gymnastics. 方法近视戴镜学生48人,在做理视健眼操前后,用彩色多普勒测定眼动脉的收缩期峰值速度和阻力指数。
Results The peak systolic velocity was speeded up and the resistive index decreased significantly after ocular gymnastics ( both P < 0.001). 结果做理视健眼操后眼动脉的收缩期峰值速度比操前明显增快(P<0.001)。
