Comparison of Tono-Pen and Goldmann applanation tonometers for measurement of intraocular pressure in healthy children
Journal of AAPOS, 06/20/2012
Bradfield YS et al. – In normal children, average differences between intraocular pressure (IOP) measured by Tono–Pen and Goldmann applanation tonometer were small, although there was substantial test–retest variability. Younger age was associated with larger average differences, as was higher IOP in the office setting.
