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 six to 14 years. Intraocular pressure (IOP) was measured using the Tono-Pen XL in both eyes of all subjects on two different occasions within a median of nine days. Refractive error was measured by noncycloplegic autorefraction. Data from right eyes only are presented. RESULTS: There was no average difference in the IOP between occasions. The 95% limits of agreement between occasions were -5.58 to 4.87 mmHg. CONCLUSIONS: The Tono-Pen XL gives reasonably repeatable readings between occasions in school-aged children.
