Pupil dilation to a startling negative sound may index subclinical depressive traits in elderly; leaves open its role as diagnostic adjunct pending larger validation studies.
Oguro et al. (2016) conducted a cross-sectional in Depression (n=41). Auditory stimuli (emotional sounds) was evaluated on Correlation between pupil dilated ratio (DR) for 'glasses broken on the floor' sound and Zung's self-depression scale (SDS) score (r = 0.314, p=0.0422). Pupil dilation in response to the emotional sound of 'glasses broken on the floor' was significantly and positively correlated with depressive scores (r = 0.314, p = 0.0422) in elderly subjects.
