Comparison of visual characteristics in children with and without learning difficulties
Abstract:
This report compares the refractive status, visual acuity, binocular status, vergence/accommodation facility, perceptual skills, and ocular health of 261 children with learning difficulties (LD) and 496 No-LD children, all between the ages of 6 and 12 years. Data reveal that among conditions diagnosed routinely by optometrists, hyperopia and perceptual skills dysfunction were more prevalent in LD children and myopia in No-LD children. No other significant between-group differences were found.

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision.

This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
