In 73 children (6-13 years old) with reading difficulty, ophthalmological evaluation showed that 18 had overt refractive errors, 18 dyslexia and no ocular anomalies, and 37 impaired fusional amplitudes, 24 of whom were dyslexic. In all Ss with poor fusional amplitudes the reading mechanism could be improved with orthoptic exercises. (Author/CL)

A comparison study involving 50 second-through-fifth graders was designed to analyze the relationships between the incidence of visual abnormalities and high and low academic achievement. Data suggested that children with deficient visual skills may experience greater problems academically. (SBH)

Disfunctions are drawn between visual perception and visual function, and four optometrists respond with further analysis of the visual perception-visual function controversy and its implications for children with learning problems. (CL)

The article reviews and interprets some of the literature that has investigated the relationships between refractive status and reading and between binocular status and reading. The characterization of the visual process is pointed out as a major research problem. (Author)

An ophthalmologist reviews the clinical features of dyslexia, gives guidelines for recognition and referral, discusses controversies regarding the management of learning disorders, and stresses the need for a multidisciplinary approach. Also included are the ophthalmologist's answers to practitioner questions. (Author/DB)

The author traces the history of optometric vision training and its influences on academic performance and presents his views on the current controversy over the value of vision training for students with learning disabilities. He concludes with a list of approximately 50 references on the topic. (CL)

A vision evaluation and enhancement program was used with 59 elementary multihandicapped students to prevent future problems in educational and social development. Ss with eye-movement difficulties, eye-hand coordination problems and/or difficulty in visual perception skills improved after program participation. (CL)

The author discusses applying J. Piaget's philosophy to the treatment of learning-related visual problems by first probing for the available knowledge in the person's ocular sensorimotor intelligence, visual thinking, and logical reasons. Then, through tasks, the individual is encouraged to engage in high-level thinking in the undeveloped areas.…

A sample of 162 fifth grade students were grouped as good, average, and poor readers on the basis of a standardized reading test to determine whether a relationship existed between binocularity and reading performance. (Author/MC)

The role of visual imagery is explored as an information processing strategy, and its relationship is counterpointed to the linguistic system. The importance of visual imagery as a diagnostic and therapeutic tool to aid both visual and nonvisual performance and learning problems is discussed. (Author)

The literature relating visual problems, reading, and academic difficulties with neurophysiological mechanisms shows positive interaction among these factors. Both visual-evoked response and encephalographic studies show parietal or occipitoparietal neurophysiological anomalies which can be used to discriminate between normal and disabled readers…

Compared on measures of saradic eye movements were 13 inadequate and 13 adequate readers (both groups all male with a mean age of 10 1/2 years). (Author)

The author contends that, while visual defects should not be confused with defects in visual perception, the identification and treatment of visual problems is an important element in the diagnosis and remediation of learning disabilities. (Author)

The author reviews aspects of visual integration which should be assessed in students with suspected learning problems: visually directed and monitored movements, visual tactual integrations, visual auditory language integrations, and visual systems integrations. (CL)
