Clinical Tonometric Measurements With the Non‐contact Tonometer

Key Points

• The study aims to compare intraocular pressure measurements between non-contact and electronic tonometers in glaucoma patients.
• Assessed intraocular pressure in clinical patients at the Ohio State University College of Optometry Glaucoma Clinic.
• Used American Optical Non-Contact Tonometer (NCT) and the Mackay-Marg Electronic Tonometer for comparison.
• Measured intraocular pressure for each eye.
• Intraocular pressure readings from the non-contact tonometer were generally lower than those from the electronic tonometer.
• Notable differences in measurements were observed for each eye assessed.
