Abstract
The value of the Random Dot Stereogram as an effective visual screening device has been emphasized in recent years. We will present evidence that 30 to 60 seconds of arc stereoacuity can be demonstrated in patients with microtropia and amblyopia, uncorrected anisometropia and unilateral congenital cataracts. The TNO Random Test is not a failsafe method to detect all types of visual problems in the pediatric age group.
