[Development of blood vessels in the human eyeball]

Blood vessels of 167 eyeballs of human embryos and fetuses have been studied, using macro- microscopical, histological and morphometrical methods. Time of appearance and differentiation of blood vessels in the eye anlage has been determined. Topography and architecture of the vitreous body artery are described in detail, as well as the vascular tunic of the lens and the pupil membrane. Regularities and time of reversal development of the vascular formations mentioned are followed during the whole intrauterine development. The data obtained add to extend our knowledge on the role of disturbances of the normal morphogenesis of the eyeball blood bed in pathogenesis of its congenital diseases.
