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

Al-Azhar International Medical Journal, 2022
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
