INTRODUCTION
Learning disabilities (LD) are neurodevelopment
disorders. LD impedes the ability to learn or use specific
academic skills like reading, writing or arithmetic. These
further results to notably reduced level of productivity,
output in school and, at home. LD types mainly include
Dyslexia, Dysgraphia and Dyscalculia which involve
problems with reading writing and mathematics
respectively.

Visual perception is the process responsible for the
reception (sensory functions) and cognition (specific
mental functions) of visual stimuli.

Visual – receptive
component is the process of taking and organizing
information from the environment, and the specific
mental functions that constitute the visual-cognitive
component provide the capacity to organize, structure,
and interpret visual stimuli.

These two components help
a person to understand what he or she sees, and both are
necessary for functional vision. The visual-cognitive
components are visual attention, visual memory, visual
discrimination, and visual imagery.

The visual-
receptive components include visual fixation, pursuit and
saccadic eye movements, accommodation, binocular
fusion and stereopsis, and convergence and divergence.

Visual-perceptual skills include the recognition and
identification of shapes, objects, colours, and other
qualities. Visual perception helps a person to make
ABSTRACT
Background: Visual perception skill related problems are important in poor academic performance in learning
disability (LD) children. Visual perception skill often not tested in LD children. The objective of the study is to
explore visual perception skill pattern among children with learning disorder.
Methods: Retrospective observational study was conducted at LD clinic of tertiary hospital. Children diagnosed with
learning disorder were includes. Visual perception data were collected using predefined standard questionnaire of
third edition total visual perception score (TVPS-3). Trained medical professional collected the details.
Results: Total 103 children diagnosed with LD were evaluated for TVPS-3. Majority of the children had all three
learning disorders-dyslexia, dysgraphia and dyscalculia. 58.42% children had co-morbid attention deficit
hyperactivity disorder. From the 7 subtests of the TVPS visual discrimination, visual memory, form constancy and
visual figure - ground affected more in boys and also in lower age children.
Conclusions: Assessment of visual perception skill in children with learning disorder is crucial. Visual perception
rehabilitation with other management of LD can benefit the overall functionality of these children.
Keywords: Attention deficit hyperactivity disorder, Dyscalculia, Dysgraphia, Dyslexia, Specific learning disorder
