Abstract
PURPOSE
To report the change of pupil sizes according to age and illuminance in the normal Korean population. METHODS: Normal Koreans outpatients who never had a history of ophthalmic disease were examined. The patients consisted of 320 eyes of 160 patients, which were classified into 8 age decades (teenage to 80's) with 40 eyes in each age group. The vertical and horizontal pupil size and area under 4 different illuminances (3,500, 1,200, 500, 5 lux) were measured using the Colvard pupillometer(R) (OASIS Medical, Glendora, CA, USA). RESULTS: The pupil size was significantly decreased as the age increased under each illuminance. The pupil area measured after dark adaptation was 47.30 mm2 in the teenage group, 43.32 mm2 in the 20's group, 41.94 mm2 in the 30's group, 40.98 mm2 in the 40's group, 40.61 mm2 in the 50's group, 38.60 mm2 in the 60's group, 37.78 mm2 in the 70's group and 35.45 mm2 in the 80's group. The decrease in pupil area was statistically significant. CONCLUSIONS: In the normal Korean population, a significant decrease in pupil size and area was observed with aging. The present study results provide good basic data for cataract and presbyopia refractive surgery.
