Inter-examiner reproducibility of Ocular Response Analyzer using the waveform score quality index in healthy subjects.

Purpose: To evaluate the inter-examiner reproducibility of Ocular Response Analyzer (ORA) parameters in healthy subjects using the waveform score (WS) for quality control of acquisition.

Patients And Methods: Fifteen healthy subjects had their intraocular pressure (IOP) measured with ORA by 2 masked examiners. An acquisition protocol that aimed at obtaining 4 reliable measurements in each eye with WS≥6 and with as few repeated measurements as possible was employed, whereas a maximum of 8 measurements per eye was allowed.
