Routine eye screenings for normal vision individuals have low yield. Focus health promotion on those with vision changes or high-risk factors like diabetes for effective eye care.

Area of Science:

  • Ophthalmology
  • Public Health
  • Epidemiology

Background:

  • Determining optimal screening frequency for normal vision requires understanding vision loss incidence and causes.
  • Population-based data is crucial for evidence-based recommendations on eye care intervals.

Purpose of the Study:

  • To ascertain the incidence and etiology of vision loss.
  • To inform the ideal frequency for routine eye examinations in individuals with normal baseline vision.

Main Methods:

  • Prospective, population-based cohort study.
  • Participants aged 40+ underwent standardized eye examinations.
  • Included visual acuity, visual fields, and dilated fundus examination.

Main Results:

  • 5-year incidence of vision loss (<6/12 acuity) was 2.39% in the cohort.
  • Of those with vision loss, 63% noticed a change, and 75% sought examination.
  • Only 0.88% developed asymptomatic vision loss from a normal baseline.

Conclusions:

  • Frequent screening for normal-sighted individuals has low yield and questionable cost-effectiveness.
  • Targeted health promotion for symptomatic individuals and high-risk groups (e.g., diabetics) is recommended.
  • Consideration of risk factors like family history is advised for personalized eye care strategies.
