The Random Dot E Test is a simple, effective, random dot stereopsis screener for children. Two matched vectographs test the patient's ability to discriminate between the Raised E figure and non-stereo target. The Stereo Random Dot E Test is designed for screening children as young as three years of age. The 3D figures can only be identified with the viewing glasses, eliminating monocular clues. Test includes both adult and pediatric viewing glasses. The Random Dot E Test is recommended by the American Academy of Ophthalmology and the American Academy of Pediatrics.
