In the typical human visual system, the macula allows for high visual resolution. Damage to this area from diseases, such as age-related macular degeneration (AMD), causes the loss of central vision in the form of a central scotoma. Since no treatment is available to reverse AMD, providing low vision rehabilitation to compensate for the loss of…

This paper reports an investigation of the effectiveness of vision screening by the Modified Telebinocular Technique (MTT) when compared to the more cumbersome but highly valid and reliable Modified Clinical Technique (MCT). Data on 102 school children were collected using the MCT. The same children were then given the MTT to establish comparison…

Visual persistence was investigated in adults with and without dyslexia in order to determine whether dyslexic adults demonstrate problems similar to those found in childhood dyslexia. Results showed that sensitivity of dyslexic adults was impaired when parts of a test stimulus were presented to adjacent retinal areas, suggesting that under…

THE RELATIONSHIP OF AUDITORY-VISUAL AND TACTUAL-VISUAL INTEGRATION TO INTELLIGENCE AND READING ACHIEVEMENT WAS INVESTIGATED. IN ADDITION, THE RELATIONSHIP OF THE TWO INTERSENSORY INTEGRATION TASKS TO EACH OTHER AND TO THE TYPE OF READING ERRORS MADE ON AN ORAL DIAGNOSTIC READING TEST WAS ALSO EXPLORED. THE SAMPLE WAS COMPOSED OF 121 WHITE…

THE AMERICAN OPTICAL (AO) COMPANY'S SIGHT SCREENER, A PORTABLE BINOCULAR INSTRUMENT DESIGNED FOR MASS VISION TESTING, WAS EVALUATED AT THE UNIVERSITY OF MARYLAND READING AND STUDY SKILLS LABORATORY TO DETERMINE ITS CAPACITY TO IDENTIFY STUDENTS NEEDING PROFESSIONAL EYE EXAMINATIONS PRIOR TO READING INSTRUCTION. DATA FROM 106 PROBATIONARY FRESHMEN,…

AUDIOMETRIC AND VISUAL PROCEDURES WERE COMPARED ANALYTICALLY AND/OR DESIGNED TO ESTABLISH TEST METHODS FOR TRAINABLE MENTAL RETARDATES IN THE IQ RANGE OF 23-47 AND BELOW THE MENTAL AGE OF 4 YEARS. THE NUMBER OF SUBJECTS WAS 26 FOR THE AUDITORY PROGRAM AND 25 FOR THE VISUAL. EACH OF THE SUBJECTS WAS STUDIED ON AN INDIVIDUAL BASIS. DATA WERE…

A study was conducted to determine if there were significant differences in vision between beginning readers who learn to read easily and those who learn with difficulty (dyslexics). In addition, the study examined the mean of the high achievers (rather than expert opinion) to discover the degree to which visual efficiency was normally needed for…
