Evaluation of Keeler Pulsair non-contact tonometry: reliability and reproducibility.
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.
