Area of Science:

  • Optometry
  • Ophthalmology
  • Rehabilitation Science

Background:

  • Low-vision care is a recognized and valued optometric service.
  • Evaluating the outcomes of low-vision care is crucial for its integration into healthcare systems.

Purpose of the Study:

  • To review the literature on the prevalence and impact of low vision.
  • To examine how low-vision interventions affect individuals with visual impairments.
  • To explore methods for evaluating the impact of low-vision care.

Main Methods:

  • Systematic literature review.
  • Analysis of studies on low vision prevalence, impact, and intervention outcomes.
  • Examination of evaluation methodologies for low-vision care.

Main Results:

  • Low-vision interventions are highly valued by patients and significantly impact daily life.
  • Quantifying the broad outcomes of low-vision care presents a considerable evaluation challenge.

Conclusions:

  • Health-related quality of life (HRQoL) assessment is a valuable approach for outcome evaluation.
  • Standardized HRQoL instruments should be applied to the visually impaired population.
  • Further optometric research is needed to address unresolved issues in outcome evaluation.
