PURPOSE: To determine normative dynamic pupillometry data in healthy Indian adults and to investigate the effect of age on various pupillary parameters. METHODS: Pupillometry measurements were obtained on healthy participants using an automatic dynamic pupillometry device, the NPi-200 (NeurOptics Inc., Irvine, CA, USA). Various measurements, including neurologic pupil index (NPi), resting pupil size (Size), minimum pupil diameter (MIN), percentage change in pupil size (CH), constriction velocity (CV), maximum constriction velocity (MCV), latency (LAT), and dilatation velocity (DV), were obtained in routine clinical settings and analyzed statistically for change with age...
