Abstract
PURPOSE: The purpose of this study was to assess the interoccasion repeatability of the Tono-Pen XL portable applanation tonometer in school-aged children. METHODS: Thirty-one normal children were recruited from The Ohio State College of Optometry Pediatric Clinic. They ranged in age from 6 to 14 years. Intraocular pressure was measured using the Tono-Pen XL in both eyes of all subjects on two different occasions within a median of 9 days. Refractive error was measured by noncycloplegic autorefraction. Data from right eyes only are presented. RESULTS: There was no average difference in the intraocular pressure between occasions. The 95% limits of agreement between occasions were -5.58 to 4.87 mm Hg. CONCLUSIONS: The Tono-Pen XL gives reasonably repeatable readings between occasions in school-aged children.
