The purpose of this study was to determine inter-and intra-examiner repeatability of
measurements of interpupillary distance (IPD). Three methods were used: Viktorin's, corneal …

Background The interpupillary distance (IPD) is usually measured between the centers of
the pupils (anatomical IPD) or between the visual axes (physiological IPD). We have …

The variation in the measurement of an inter‐pupillary distance and monocular centration
distance by 54 registered practitioners using a 'pd rule'was investigated. Their estimate of …

Interpupillary measurements were made employing four techniques. Three methods
employed pupillometers, two of which measured interpupillary distances at infinity and one …

Purpose. To determine the accuracy and repeatability of participants determining their own
interpupillary distance (PD). Methods. Fifty-two healthy and naïve participants were enrolled …

Background Interpupillary distance (IPD) is important in developmental anatomy, genetics,
design of optical instrumentation, ocular diagnostics, and optical prescribing. IPD frequently …

Introduction: The plusoptiX photoscreener provides a number of measurements, including
an estimate of inter-pupillary distance. We compare the plusoptiX photoscreening …

We have investigated the distant and near interpupillary distance (IPD) of three groups of
females of Arab origin. Average values and range of values have been determined for …

Purpose To compare the effects of age and near phoria on interpupillary distance measured
at far (FIPD) and near (NIPD) using the Viktorin's and pupillometer (PD-5) methods. Methods …

Purpose: The purpose of this study was to determine the reliability of interpupillary distance
(IPD) and pupil diameter (PD) measures using an infrared eye tracker and central point …
