Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Effect of Child Delivery on the Intraocular Pressure

Further study details as provided by Meir Medical Center:

Primary Outcome Measures:
  • Intraocular Pressure [ Time Frame: During child delivery ]
    Intraocular pressure during different stages of child delivery.

Enrollment: 30
Study Start Date: August 2010
Study Completion Date: August 2012
Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Pregnant women
Healthy pregnant women

Detailed Description:
Little is known about the changes in intraocular pressure (IOP) during child delivery. During labor there are several stages which are accompanied by many physiological changes and pharmacological interventions that may potentially influence the IOP. Among these are delivery position (lying versus sitting or kneeling), vascular changes and pharmacological effects (anesthetic agents, oxytocin and other drugs). The purpose of this study is to evaluate the effect of child delivery on the intraocular pressure (IOP) in healthy women. This will expend our understanding of the physiology of labor and its effect on the eye and it may serve as basis to determine the management of labor.
