    The effect of hemodialysis on intraocular pressure
    (WROCLAW MEDICAL UNIV, 2018-01-01) Kilavuzoglu, Ayse Ebru Bahadir; Yurteri, Gurkan; Guven, Nurgul; Marsap, Savas; Celebi, Ali Riza Cenk; Cosar, Cemile Banu
    Background. The effect of hemodialysis (HD) on intraocular pressure (IOP) has been investigated before, but there is a lack of consensus. Clinicians dealing with renal failure patients are interested in the potential negative effects of HD on IOP and the course of glaucoma. Objectives. The aim of this study was to investigate the effects of HD on IOP in patients with end-stage renal disease. Material and methods. This prospective study included 106 patients who were receiving outpatient hemodialysis. Patient history of systemic and ophthalmologic conditions was recorded. Serum osmolality (mOsm), blood urea nitrogen (BUN), blood glucose (BG), bicarbonate (BC), and hematocrit (Hct) levels at the start of HD (pre-HD), at the end of HD (end-HD), and 30 min after HD (post-HD) were measured. Systolic and diastolic blood pressures (SBP and DBP) and IOP were measured at pre-HD, 1-hour intervals during HD, end-HD, and post-HD. Results. A significant decrease in mOsm and BUN and a significant increase in BG, BC, and Hct levels were observed at end-HD (p < 0.05). Mean IOP was 16.71 +/- 2.51 mm Hg at pre-HD, 15.52 +/- 3.18 mm Hg at end-HD, and 15.23 +/- 2.73 mm Hg at post-HD (p = 0.001

    Correlation between corneal thickness, keratometry, age, and differential pressure difference in healthy eyes
    (NATURE RESEARCH, 2021-01-01) Colakoglu, Ahmet; Colakoglu, Iffet Emel; Cosar, Cemile Banu
    To determine the use of differential pressure difference (DPD), in air-puff differential tonometry, as a potential biomechanical measure of the cornea and elucidate its relationship with the intraocular pressure (IOP), central corneal thickness, corneal curvature, and age. This study comprised 396 eyes from 198 patients and was conducted at Acibadem University, School of Medicine, Department of Ophthalmology, Istanbul, Turkey. The central corneal curvature and refraction of the eyes were measured using an Auto Kerato-Refractometer (KR-1
