Macular dazzling test on normal subjects

Abstract

The macular dazzling test was performed on 240 healthy eyes, classified into six groups according to the ages of the subjects. The test was used to assess both long distance and short distance vision with a simultaneous study of the influence of mydriasis and miosis. The MDT is a test easy to perform, requires a minimum of co-operation by the subject, and gives repeatable results. The MDT values increase significantly as the age of the subject increases. The sex of the subject has no influence on it, and there are no significant differences between a subject's right and left eyes. Mydriasis does not affect the MDT, but miosis reduces the recovery period. All the values are statistically greater for long distance vision than for short distance vision.
