Predictors of adequate correction following vision screening failure

Area of Science:

• Ophthalmology
• Public Health
• Pediatrics

Background:

• Vision screening identifies children needing further examination for refractive errors.
• Compliance with follow-up care is crucial for addressing identified vision impairments.
• Understanding factors influencing compliance can optimize vision care delivery.

Purpose of the Study:

• To investigate associations between care models, demographics, ocular factors, and compliance with vision referral.
• To evaluate if different vision screening and care approaches impact follow-up adherence.

Main Methods:

• Analysis of data from 798 children with refractive errors in the Collaborative Longitudinal Evaluation of Ethnicity and Refractive Error Study.
• Comparison of a screening model (referral letters) versus a complete care model (free examination and glasses).
• Logistic regression used to identify predictors of compliance, including age, visual acuity, and socioeconomic factors.

Main Results:

• Overall compliance with vision referral was 28%.
• Age and uncorrected visual acuity (logMAR) were significant predictors of compliance.
• Care model, ethnicity, and sex were not associated with compliance, except for an interaction where poorer unaided visual acuity improved compliance in the complete care model.

Conclusions:

• Standard referral protocols may be as effective as more intensive complete care models for improving vision screening compliance.
• Comprehensive care models may enhance compliance for children with significantly poorer unaided visual acuity.
• Targeted interventions may be needed for specific subgroups to improve follow-up adherence.
