title: The effectiveness of the random dot E stereotest as a preschool vision screening instrument.
abstract: Sixty nursery-school children (ages 39--76 months) were screened with a modified-clinical method (visual acuity, retinoscopy, cover test, NPC) and with a relatively new vectographic test for stereopsis--the Random Dot E. Screening outcomes indicate that the RDE was as effective in identifying children for referral as was the modified clinical battery. Implications are discussed.
