Condition of the microcirculatory bed of the bulbar conjunctiva in physiological and pathological pregnancies

Of them: 30 healthy women make the control group; the second group includes 60 healthy women at their first and second half of pregnancy; the third group includes 60 women with pregnancy developing against the background of noncomplicated insulin-dependent diabetus mellitus during their first and second half of pregnancy.

Diameters of all vessels in the hemomicrocirculatory bed are significantly increased, as compared to those in the control group. In the women suffering from diabetus mellitus, during the first half of pregnancy certain changes in the picture of the vascular network is observed, as well as an increased convolution. uneveness in distribution of blood vessels; in the second half of their pregnancy a pronounced deformity of the vacular network is observed, decreasing diameter of afferent vessels and an essential dilatation of postcapillaries and venules are registered.
