To evaluate the effect of mydriasis on the visual acuity and stereopsis according to the refraction and age.
This study included 112 eyes of 56 patients, which were divided into three groups according to the refraction. The best corrected visual acuity and stereopsis were compared between without and with mydriasis in all groups according to age.
After mydriasis, at near, naked visual acuity was decreased in 0.53 logMAR, average and stereopsis was also deceased from 60 seconds to 200 seconds. At far, the naked and best corrected visual acuity had no significant change. At near, there was no significant difference on the degree of decreased visual acuity and stereopsis according to refraction, but in emmetropic patients, the visual acuity was significantly decreased. Patients older than forty–five years old had less decreased visual acuity compared with younger than ten years old.
After pupil dilatation, there were significant decreased visual acuity and stereopsis, there was little change at far. The degree of decreased vision was different according to the refraction and age, therefore it would be helpful to explain the anticipating result.
V.A., visual acuity
*Statistically no significant differences at the 99% level
