The Pupillary Light Reflex (PLR) is an involuntary reflex that changes the size of the pupil in response to varying light conditions. PLR analysis is widely employed in the evaluation of several neurological and ocular conditions and quantitative pupillometry requires the use of expensive ophthalmic instruments. In this paper, we describe an empirical evaluation we performed on the use of a commercially available smartphone (Apple iPhone 6s) to make quantitative measurements of PLR. Measurements were made with 30 healthy volunteers, equally distributed on three age ranges, including also different eye colors. Additionally, we also performed an assessment of the risks inducted by the use of the flash very close to the eye, showing that, if correctly used, it is by far below the constraints of international safety standard.

Abstract
The Pupillary Light Reflex (PLR) is an involuntary reflex that changes the size of the pupil in response to varying light conditions. PLR analysis is widely employed in the evaluation of several neurological and ocular conditions and quantitative pupillometry requires the use of expensive ophthalmic instruments. In this paper, we describe an empirical evaluation we performed on the use of a commercially available smartphone (Apple iPhone 6s) to make quantitative measurements of PLR. Measurements were made with 30 healthy volunteers, equally distributed on three age ranges, including also different eye colors. Additionally, we also performed an assessment of the risks inducted by the use of the flash very close to the eye, showing that, if correctly used, it is by far below the constraints of international safety standard.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
