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 […]
