Insights

This study developed a comprehensive list of vision-related tasks for children with visual impairment, categorized by difficulty and age. This resource aids in creating better functional vision assessments for this population.

Area of Science:

  • Ophthalmology and Vision Science
  • Pediatric Occupational Therapy
  • Rehabilitation Medicine

Background:

  • Functional vision (FV) is crucial for the development of children with visual impairment.
  • Existing methods for measuring FV in this population are not well-established.
  • A need exists for a structured approach to assessing FV considering age and task difficulty.

Purpose of the Study:

  • To establish a comprehensive set of vision-related tasks for assessing functional vision in children with visual impairment.
  • To categorize these tasks by difficulty level and age appropriateness.
  • To inform the development of standardized FV assessment tools.

Main Methods:

  • A sequential multi-method design was employed, including a scoping review and qualitative content analysis.
  • A focus group was used to categorize identified tasks by difficulty and dependency.
  • The Occupational Therapy Practice Framework (OTPF-4) guided the categorization process.

Main Results:

  • A total of 180 vision-related tasks were identified across 22 studies and 16 participants.
  • Tasks were categorized into 17 activities and five occupations (ADL, IADL, education, play, social participation).
  • Activities of daily living (ADL) were found to be the easiest, while social participation was the most challenging.

Conclusions:

  • A comprehensive, difficulty-level-based list of vision-related tasks for children with visual impairment was developed.
  • This list provides a foundation for creating standardized instruments to assess functional vision.
  • The findings support tailored interventions and assessments for children with visual impairment.
