Difference in Intraocular Pressure between Sitting Versus Supine Positions in Healthy and Glaucomatous Children by Rebound tonometery

Abstract

Background: Glaucoma's biggest treatable risk factor is elevated intraocular pressure (IOP) . Many factors have an impact on IOP, including body posture. Due to its convenience, lack of requirement for topical anaesthetic, and repeatable results, rebound tonometry has been claimed to be equivalent to the Goldmann applanation tonometer (GAT). Aim of The Work:To study the effect of body posture (supine position versus sitting position) on the intraocular pressure (IOP) measurements in normal healthy children and glaucomatous children by using a Rebound tonometry. Patients and Methods:The study was carried out on 80 children, divided into 20 cases of children with glaucoma, and 60 children with normal healthy eyes as control, all children attending the outpatient pediatric ophthalmology clinics, of
