[Practising appropriate vision check scheme in eye diseases mass screening works]

Area of Science:

• Ophthalmology
• Public Health
• Pediatrics

Context:

• Childhood vision screening in China predominantly uses uncorrected distance visual acuity.
• This traditional method is insufficient for childhood vision development and can lead to unnecessary interventions.
• Adult vision screening in some areas also relies on uncorrected distance visual acuity.

Purpose:

• To propose improved vision screening strategies for children and adults in China.
• To address the limitations of the current uncorrected visual acuity-based system.
• To enhance the accuracy and efficiency of mass vision screening programs.

Summary:

• The current Chinese vision screening system, based on uncorrected distance visual acuity, is inadequate for childhood vision development and adult eye disease detection.
• Novel amblyopia diagnostic criteria and a combination of uncorrected, presenting, and corrected visual acuity are recommended for preschool children.
• Presenting vision is suggested for adult impairment screening, with tailored schemes for specific eye diseases.

Impact:

• Adoption of new criteria can reduce unnecessary repetitive screenings and treatments for corrected ametropia in children.
• Improved screening methods will lead to earlier and more accurate detection of vision impairments and eye diseases.
• Enhanced collaboration among healthcare professionals is crucial for effective children's eye disease screening projects.
