Abstract

Many women feel the physical burden during mammography as pain. We examined the pain-related pupil dilation response during mammography. The pupil sizes of 24 women were measured during mammography excluding x-ray irradiation. Their mean pupil diameter was 2.9 mm in relaxation phase before mammography, while it was 3.2 mm in a few seconds after breast compression. The difference in pupil diameter between the relaxation and pressure phases was statistically significant.
