“…Since pupillary resting diameter reflects the balance between opposing sympathetic and parasympathetic autonomic systems, the decrease in PD as age increased might have been related to either increasing parasympathetic effects or decreasing sympathetic input. Additionally, in a recent study, Schroder et al showed that this decrease in PD with age is largest for scotopic (≈0.057 mm/year) and smallest for photopic illumination (≈0.025 mm/year).…”

“…Pupillometry devices can be used to obtain automatic, multiple, quantitative measurements of pupillary response to light under controlled, ambient lighting conditions. This improves the repeatability of the examinations, solves the problem of clinician‐dependent errors and reduces false negative responses …”

Background To compare the static and dynamic pupillometry measurements in patients with pseudoexfoliation syndrome (PES), patients with pseudoexfoliation glaucoma (PEG) and age‐matched healthy subjects using an automatic quantitative pupillometry system. Methods This prospective, cross‐sectional study consisted of 40 patients with PES, 30 patients with PEG and 43 control subjects. Static pupillometry measurements including scotopic pupil diameter, mesopic pupil diameter, low photopic pupil diameter, and high photopic pupil diameter were undertaken. Subsequently, dynamic pupillometry measurements including resting diameter, amplitude of pupil contraction, latency of pupil contraction, duration of pupil contraction, velocity of pupil contraction, latency of pupil dilation, duration of pupil dilation, and velocity of pupil dilation were undertaken. These measurements were compared between the groups. Results The scotopic, mesopic, and low photopic pupil diameter values were statistically significantly lower in patients with PES and PEG compared with controls (p < 0.001). However, these parameters were similar between the patients with PES and PEG (p > 0.05). The mean values of high photopic pupil diameter were similar within all groups (p = 0.54). The amplitude of pupil contraction values of the patients with PEG was statistically significantly lower than the patients with PES and the controls (p < 0.05). Patients with PES also had significantly lower amplitude of pupil contraction values compared with controls (p < 0.001). Additionally, the velocity of pupil contraction values was statistically significantly higher in control subjects when compared to the patients with PES and PEG (p < 0.05). Conclusion This study demonstrated that accumulation of pseudoexfoliative material can cause alterations in static and dynamic pupillary characteristics and the progression from PES to PEG may be associated with reduced amplitude of pupil contraction values.
