Ophthalmic arterial blood flow parameters were measured by color doppler imaging in 227 cases(454 eyes)of normal pregnancy

32 cases(64 eyes)of healthy non-pregnancy.The results showed that diameters

Vmax

Vmean and Vmin of ophthalmic arterial blood flow on the left and right eyes were obviusly higher in those with normal pregnancy than those with non-pregnancy.This difference was highly significant(P<0.01)

while RI and PI were not significant in them(P>0.05).However

the RI and D were also not significant at various pregnancy perios

There were no significant differences for parametes mentioned above between the right and left eyes in pregnancy and non-pregnancy. It is belived that the results provide the basis for diseases cauxing ophtalmic arterial hemodynamic abnormal changes to be detected by way of color doppler imaging in pregnancy women.
