Physiological Changes of Intra Ocular Pressure during First and Third Trimester of Pregnancy

Pregnancy brings in an increase in hormones that may cause changes in vision by altering the strength of refraction. The temporary changes in vision will return to normal after delivery. The primary objective is to identify the ocular changes in both eyes during first and third trimesters of normal pregnancy by doing ocular examination along with regular antenatal check-ups to detect the blood pressure change, to diagnose pre-eclampsia and other ocular disorders at an early stage. Intra Ocular Pressure of both eyes was measured by Schiotz tonometry.
