Interdevice Agreement between a Smartphone and a Commercial Pupillometer.

Background: The reliability of dynamic pupillometry parameters varies from one pupillometer to another, making it difficult to standardize the values for any particular device. Hence, further studies are required to evaluate the agreement of various pupillometer devices and explore their utility in routine clinical settings.

Aim: This study sought to evaluate the agreement between smartphone and commercial pupillometer measurements in routine clinical settings.
