Brief summary
PURPOSE. To evaluate the impact of self-acting eyetracking and retest software on the reproducibility of retinal nerve fiber layer (RNFL) thickness measurements in glaucoma patients and healthy control subjects using Spectralis® SD-OCT. METHODS. RNFL thickness was measured in 56 normal and 47 glaucomatous eyes by one operator within one session with a brief rest between measurements. Three measurements were taken with the eye-tracker and retest function, and three were taken without this function, alternating between measurement methods. * Trial with medical device
