Summary: Purpose: The aim of this paper was to describe physiological changes in intraocular pressure and capillary retinal blood flow during normal pregnancy. Materials and methods: Healthy women with uncomplicated singleton pregnancy were examined longitudinally et ten-week intervals throughout the pregnancy. All subjects were free from any systemic or ocular diseases, without any known fetal or maternal risk factors. Had no history of orbital trauma, and possessed visual acuity correctable to 20/20. Full ophthalmologic examination (visual aquity, refractive error, intraocular pressure, slit lamp examination and fundus exam) was performed. Retinal blood flow measurements were performed with the Heidelberg Retina Flowmeter in first, second, and third term of their pregnancy. Results: During pregnancy decrease of intraocular pressure was observed. The differences between values at the beginning of pregnancy and following examinations were found to be: 0.7 ?0.34 mmHg, 1.42 ?0.31 mmHg, 2.42 ?0.59 mmHg respectively. In these subjects, pregnancy decreased IOP by 15.7%. Retinal blood flow analysis demonstrated the increase of retinal blood flow during following stages of pregnancy in both eyes in all cases. Conclusions: The results revealed increase im capillary retinal blood flow and consistent, statistically significant decrease in intraocular pressure during pregnancy.
