Area of Science:

  • Ophthalmology
  • Health Economics
  • Rehabilitation Science

Background:

  • Low vision significantly impacts daily life and quality of life for individuals with conditions like diabetic retinopathy and age-related macular degeneration.
  • Effective vision rehabilitation services are crucial for improving functional abilities and well-being in visually impaired populations.
  • The cost-effectiveness of basic vision rehabilitation services (basic-VRS) in Portugal requires further investigation to inform healthcare planning.

Purpose of the Study:

  • To assess the cost-effectiveness of a basic vision rehabilitation service (basic-VRS) compared to usual low vision care in Portugal.
  • To evaluate the impact of basic-VRS on self-reported visual ability, psychosocial outcomes, and health-related quality of life.
  • To provide evidence for better planning of low vision services and reduce barriers to accessing basic-VRS.

Main Methods:

  • A parallel-group, randomized controlled trial comparing basic-VRS with usual low vision care.
  • Inclusion criteria: visual acuity 0.4-1.0 logMAR, diabetic retinopathy or age-related macular degeneration, age 18+, community-dwelling.
  • Primary outcome: visual ability (Massof Activity Inventory). Secondary outcomes: reading ability, quality of life, anxiety, depression, social support. Cost-effectiveness analysis from a healthcare system perspective.

Main Results:

  • The primary outcome measure is visual ability, assessed using the Massof Activity Inventory.
  • The study anticipates that the basic-VRS intervention will enhance overall visual ability.
  • Cost-effectiveness will be determined by calculating the cost per unit of utility, adopting a healthcare system perspective.

Conclusions:

  • This study will offer valuable data on the effectiveness of basic-VRS for self-reported visual ability.
  • Findings are expected to aid in optimizing the provision of low vision services.
  • The research aims to contribute to reducing obstacles in accessing essential vision rehabilitation care.
