Vision screening for frail older people: a randomised trial

Area of Science:

• Gerontology
• Ophthalmology
• Public Health

Background:

• Frail older adults are at higher risk of visual impairment.
• Vision impairment significantly impacts quality of life in older populations.
• Early detection and management of vision problems are crucial for maintaining independence.

Purpose of the Study:

• To evaluate the effectiveness of optometrist-led vision screening and management.
• To assess the impact on visual acuity and vision-related quality of life.
• To determine benefits for frail older individuals in a community setting.

Main Methods:

• Randomized controlled trial involving 616 participants aged 70+ in Sydney, Australia.
• Intervention group received comprehensive eye examinations and treatment referrals.
• Control group received no vision assessment or intervention.

Main Results:

• No statistically significant difference in distance or near visual acuity between groups after 12 months.
• No significant difference in vision-related quality of life scores (National Eye Institute Visual Function Questionnaire).
• Specific interventions like new glasses or referrals for glaucoma/cataract surgery did not yield measurable improvements in the screened group.

Conclusions:

• Optometrist-led vision screening and management did not improve vision or quality of life in frail older adults.
• The current screening approach may not be effective for this population.
• Further research is needed to identify effective interventions for visual impairment in frail older individuals.
