title: Evaluation of Keeler Pulsair non-contact tonometry: reliability and reproducibility.
abstract: Intraocular pressure was evaluated in 414 eyes using Keeler Pulsair tonometry in comparison with values obtained by Goldmann tonometry. No statistically significant differences were found between the two techniques. Landis K statistical analysis was used to evaluate the measurements obtained by two operators in 125 eyes, with the results indicating good reproducibility. In 20 eyes, a statistically significant difference was found between values obtained with patients in the seated vs supine positions, whereas measurements made with subjects' heads in a supported or unsupported position yielded no statistically different values.
