The study group included 180 eyes of 90 healthy volunteers in different age groups. We aimed to evaluate the normative pupillometry values and mean pupil dilatation speed in healthy individuals in different age groups in our study. Also, age had a positive correlation with MAX, MIN, and CON.
We found males to have significantly greater MCV and CON than females (p < 0.05). We sought to establish normative data in this group. Quantitative pupillometry can be a useful tool for screening pediatric patients. 84.2 and 95.8% of participants showed resting pupil asymmetry of ≤0.5 mm and ≤ 1.0 mm, respectively. Age had a positive correlation with MAX, MIN, and CON. Iris color was noted as light, intermediate, or dark.ġ96 eyes of 101 participants (42.6% male, ages 1-17 years, average age 10.3 years) were analyzed. Quantitative data included maximum (MAX) and minimum (MIN) diameters, constriction percentage (CON), latency (LAT), average (ACV) and maximum (MCV) constriction velocities, average dilation velocity (ADV), and 75% recovery time (T75). Pupillometry was obtained prospectively for consecutive, normal patients < 18 years old being evaluated by Lurie Children's Ophthalmology. We aim to establish normative data for scotopic pupillary size and function in the pediatric population in a clinical setting. Noting size, reactivity, and consensual response is critical in assessing for optic nerve dysfunction. Pupillary evaluation is a crucial element of physical exams.
