Summary
Children with developmental dyslexia report more vision symptoms than typical readers. These symptoms correlate with ocular motor tracking issues in dyslexic children, suggesting clinical relevance.
Area of Science:
- Ophthalmology
- Developmental Psychology
- Educational Neuroscience
Background:
- Anecdotal reports suggest vision problems in children with developmental dyslexia (DD).
- Empirical studies investigating vision symptoms in DD are limited.
- Understanding these symptoms is crucial for effective intervention.
Purpose of the Study:
- To document self-reported vision symptoms in children with DD compared to typically reading (TR) peers.
- To explore correlations between vision symptoms and sensorimotor eye measures (vergence, accommodation, ocular motor tracking).
Main Methods:
- Prospective group comparison observational study.
- Assessed 28 children with DD and 33 TR children (ages 7-11).
- Utilized psychoeducational testing, comprehensive sensorimotor eye exams, and the Convergence Insufficiency Symptom Survey (CISS).
Main Results:
- Children with DD reported significantly more vision-related symptoms (CISS-V) than TR children.
- Ocular motor tracking deficits were associated with visual symptoms specifically within the DD group.
- Cognitive-related symptom scores (CISS-C) did not differ significantly between groups.
Conclusions:
- Vision-related symptom surveys are valuable for identifying potential issues in children with DD.
- Comprehensive eye examinations focusing on sensorimotor function are clinically relevant for children reporting vision symptoms.
- Findings highlight the importance of visual assessments in the management of developmental dyslexia.

1.5K
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
