Summary

Community screening for vision problems in older adults does not improve vision. This review found no evidence that mass screening of asymptomatic seniors leads to better eyesight outcomes.

Background:

Multicomponent screening aims to broadly assess older adults.
The effectiveness of vision screening within these programs depends on demonstrable vision improvement.

Purpose of the Study:

To evaluate the impact of mass screening for visual impairment in older populations on their vision.

Main Methods:

Systematic review of randomized controlled trials (RCTs) involving community-based screening for vision impairment in individuals aged 65 and above.
Searches included major databases up to April 1998; data extraction and quality assessment were performed independently.

Main Results:

Five trials with 3494 participants assessed vision outcomes over 2-4 years, primarily using self-reported measures.

No significant difference in reported visual problems was observed between intervention and control groups (RR 1.03, 95% CI 0.92-1.15).

Conclusions:

Current evidence does not support community-based screening of asymptomatic older individuals for improving vision.
