| 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. |
