Effect of Manual Upper Eyelid Elevation on Intraocular Pressure Measurement by Four Different Tonometers

Abstract Significance: This study is the first to show that the manual upper eyelid elevation (manual UEE) that is commonly used to prevent disruption of the IOP measurement due to blinking or upper eyelid contact with the tip of the tonometer does not affect the IOP values. Purpose: We investigated whether manual UEE affects the […]

Determining Significant Elevation of Intraocular Pressure Using Self-tonometry

Abstract Significance: Icare HOME rebound tonometry is increasingly adopted into clinical practice for IOP phasing of glaucoma patients and suspects. Because of measurement differences with applanation tonometry and diurnal fluctuations, interpretation of the IOP measured with Icare HOME phasing can be challenging. Purpose: The purpose of this study was to use a large patient cohort […]

Repeatability and agreement of intraocular pressure measurement among three tonometers

Abstract Background: Elevated intraocular pressure (IOP) is one of the causes of irreversible optic nerve head damage and visual field loss. It is often measured with applanation tonometers but the use of rebound tonometry devices has been proposed as an alternative to assess IOP. Rebound tonometers have also been proposed as a method for patients […]

Changes in preoperative corneal measurements following same-day intraocular pressure testing with rebound tonometry

Abstract Purpose: To evaluate the extent to which rebound tonometry affects corneal surface properties and preoperative corneal measurements. Setting: Four cornea specialty private practices. Design: Prospective case series. Methods: Visual acuity testing, corneal topography, keratometry, and grading of corneal staining were performed on both eyes of 60 randomly selected, previously scheduled patients. Technicians then performed […]

Feeling the pressure: a cross-sectional study exploring feasibility of a healthcare Pop-Up for intraocular pressure measurements in shopping centres in England

Abstract Objectives: To test the hypothesis that a shopping centre Pop-Up health check combining an intraocular pressure (IOP) check with a general health check (blood pressure (BP)) is more readily accepted by the general public than an IOP check only. We investigate public awareness of IOP compared with BP and the feasibility of measuring IOP […]

Analysis of reproducibility, evaluation, and preference of the new iC100 rebound tonometer versus iCare PRO and Perkins portable applanation tonometry

Abstract Objectives: To analyze the reproducibility of the new iC100 rebound tonometer, to compare its results with the applanation tonometry and iCare PRO and to evaluate the preference between them. Materials and methods: For the study of reproducibility, 15 eyes of 15 healthy Caucasian subjects were included. Three measurements were taken each day in three […]

Comparison of rebound tonometry and non-contact airpuff tonometry to Goldmann applanation tonometry

Abstract Purpose: The aim of this study was to compare the intraocular pressure measurements obtained from healthy subjects with the rebound tonometry, non-contact airpuff tonometry, and Goldmann applanation tonometry in different age groups. Methods: A total of 180 eyes of 90 healthy subjects were included in the study. According to the subjects’ ages, the eyes […]
