In addition, methods are provided for comparing one or both of such capillary blood flow patterns with patterns of capillary blood flow obtained from the woman's forehead at the anastomoses of the supratrochlear branches of the ophthalmic artery, for evaluating a physiological condition of a woman. Systems and devices for carrying out these evaluations, as well as for observing such capillary blood flow patterns separately, are provided.Other References
