Abstract
The ability of the human eye to perceive depth was measured using a specially designed instrument Visual acuity and both monocular and binocular stereoacuity were measured when viewing the instrument directly and via a videoconferencing link Ten subjects with an average age of 32 5 years range 24 50 took part in the study The group mean visual acuity using both eyes under normal test conditions was 0 04 logMAR Snellen 6 5 compared with 0 18 logMAR Snellen 6 10 for the video link The mean stereoacuity using both eyes was 37 SD 18 under normal test conditions When a videoconferencing link was used the mean stereoacuity fell to 1218 SD 1203 using one eye and to 1651 SD 1419 using both eyes The ability to perceive depth remotely via a video link was significantly decreased compared with normal test conditions
