About this study
Official title: Integrative Neurodevelopmental Approach to Cerebral Vision Impairment (CVI): Screening and Subtyping in Early Childhood
Cerebral visual impairment (CVI) is one of the leading causes of pediatric visual impairment and negatively impacts the development of motor, language, and cognitive skills. This study proposes to (1) establish a novel and easy to use CVI screening algorithm for infants and (2) develop CVI subtypes based on vision, motor, language, and cognition. The overarching goal is to identify CVI early and enhance our comprehension of CVI's impact on a child's development. The results will fundamentally change the approach to designing treatments for children with CVI.
Read the detailed description
Cerebral visual impairment (CVI) is the leading cause of visual impairment in children. Although the onset is typically early in life, diagnosis is often delayed until preschool age or later. Early identification is critical for optimal development. Vision is essential in incidental and intentional learning used to build foundational motor, language, and cognitive skills. The proposed research aims to (1) develop a screening algorithm for early detection of CVI and (2) establish neurodevelopmental profiles that will inform intervention for children diagnosed with CVI. The overarching hypothesis is that early detection of CVI and understanding the relationship between visual impairment and neurodevelopment are imperative for creating interventions to optimize a child's abilities. In the first aim, a novel screening algorithm for CVI detection in infants will be tested at three time points between 4-12 months corrected age. In the second aim, an interdisciplinary standardized assessment protocol will be utilized, including visual and developmental evaluations at two time points to create neurodevelopmental subtypes in young children with CVI. This proposal will be implemented by an interdisciplinary research team with a well-established track record of clinical practice and research in CVI. This innovative proposal will lead to a paradigm shift in the current approach to CVI management in young children. The findings from this study will lead to the development of a screening protocol for early detection of CVI that can be easily incorporated into medical practice by providers who routinely interact with young infants and, in time, become standard practice. Additionally, the established neurodevelopmental profiles will serve as the cornerstone for creating comprehensive clinical protocols guiding the care and treatment of children diagnosed with CVI.

Gross Motor Function Measure-66 (GMFM-66)
Time frame: Aim 2: Enrollment (Baseline) and 12 Months later
The Gross Motor Function Measure-66 (GMFM-66) is a standardized observational assessment used to evaluate gross motor function in children with cerebral palsy and other motor impairments. It measures changes in gross motor abilities over time or in response to intervention. It can be used for children aged 5 months to 16 years,
The Movement Assessment Battery for Children (MABC)
Time frame: Aim 2: At enrollment (baseline) and 12 months later
The Movement Assessment Battery for Children (MABC) is a standardized tool used to assess motor coordination and movement difficulties in children and adolescents aged 3 to 16 years. It is used to identify motor impairments and supports diagnosis of conditions like Developmental Coordination Disorder (DCD).
The Preschool Language Scales- 5th Edition (PLS-5)
Time frame: Aim 2: Enrollment (Baseline) and 12 Months later
This study will offer several assessments to test speech and language, depending on age and ability level. The Preschool Language Scales, Fifth Edition (PLS-5) is a standardized assessment tool used to evaluate language development in children from birth through 7 years, 11 months. It assesses both receptive (understanding) and expressive (speaking) language skills.
Rosetti Infant Toddler Language Scale
Time frame: Aim 2: At enrollment (baseline) and 12 months later
This study will offer several assessments to test speech and language, depending on age and ability level. The Rossetti Infant-Toddler Language Scale is a criterion-referenced assessment tool used to evaluate communication and language development in children from birth to 3 years of age. It identifies delays in preverbal and verbal communication skills.
Goldman Fristoe Test of Articulation (GFTA)
Time frame: Aim 2: At enrollment (baseline) and 12 months later
This study will offer several assessments to test speech and language, depending on age and ability level. For children who present with an articulation deficit, the Goldman Fristoe Test of Articulation will be administered. The GFTA is a standardized assessment used to evaluate articulation skills in individuals aged 2 to 21 years.
The Weschler Preschool & Primary Scale of Intelligence - Fourth Edition (WPPSI-IV)
Time frame: Aim 2: At enrollment (baseline) and 12 months later
This study will offer several assessments to test cognition, depending on age and ability level. The Wechsler Preschool and Primary Scale of Intelligence - Fourth Edition (WPPSI-IV) is a standardized cognitive assessment designed for children aged 2 years 6 months to 7 years 7 months. It measures intellectual functioning and helps identify cognitive strengths and weaknesses.
The Leiter International Performance Scale 3 (Leiter 3)
Time frame: Aim 2: At enrollment (baseline) and 12 months later
This study will offer several assessments to test cognition, depending on age and ability level. The Leiter International Performance Scale - Third Edition (Leiter-3) is a nonverbal intelligence and cognitive abilities test designed for children aged 3 to 18 years. It assesses nonverbal IQ, attention, memory, and processing speed.
