1. The relationship between intraocular pressure and glaucoma: An evolving concept

    Abstract Intraocular pressure (IOP) is the most important modifiable risk factor for glaucoma and fluctuates considerably within patients over short and long time periods. Our field’s understanding of IOP has evolved considerably in recent years, driven by tonometric technologies with increasing accuracy, reproducibility, and temporal resolution that have refined our knowledge regarding the relationship between […]

  4. Reliability of iCare IC100 Rebound Tonometry and Agreement with Goldmann Applanation Tonometry in Healthy and Post-myopic LASIK Patients

    Abstract Precis: Rebound tonometry offers excellent reliability for obtaining intraocular pressure (IOP) measurements in healthy and post-myopic laser-assisted in situ keratomileusis (LASIK) patients regardless of corneal parameters and axial length and regardless of the instillation of ocular topical anesthesia. Purpose: The purpose of this study was to assess the reliability of rebound tonometry, its agreement […]

  5. Agreement Among Goldmann Applanation Tonometer, iCare, and iCare PRO Rebound Tonometers; Non-Contact Tonometer; and Tonopen XL in Healthy Elderly Subjects

    Abstract Purpose: To evaluate the inter-device agreement among the Goldmann applanation tonometer (GAT), iCare and Icare PRO rebound tonometers, non-contact tonometer (NCT), and Tonopen XL tonometer. Methods: Sixty healthy elderly subjects were enrolled. The intraocular pressure (IOP) in each subject’s right eye was measured thrice using each of the five tonometers. Intra-device agreement was evaluated […]

  6. Agreement and repeatability of Icare ic100 tonometer

    Abstract Purpose: To find the agreement and repeatability of iCare IC100 tonometer. Methods: We included 150 subjects above the age of 18 years for this cross-sectional, multicenter study with intraocular pressure (IOP) ≥7 mmHg. After the initial ophthalmic examination, two masked examiners took five IOP measurements using three different instruments; Icare ic100, Icare TA01i, and […]

  10. 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 […]
