A review of paediatric vision screening protocols and guidelines

Area of Science:

• Ophthalmology and Public Health

Background:

• Vision screening is vital for early detection of visual impairments in children.
• Effective screening depends on test validity, reliability, age appropriateness, and follow-up protocols.
• Despite advancements, consensus is lacking on optimal screening age, test selection, and administrator qualifications.

Purpose of the Study:

• To review the history and evidence supporting pediatric vision screening protocols.
• To examine challenges in developing effective pediatric vision screening models, particularly in resource-limited settings.

Main Methods:

• Literature review of historical developments in pediatric vision screening.
• Analysis of evidence supporting current screening practices.
• Examination of barriers to implementing vision screening programs.

Main Results:

• Established importance of vision screening for early detection of visual conditions.
• Highlighted variability in current screening practices and lack of universal standards.
• Identified significant barriers to widespread implementation, especially in low- and medium-income countries.

Conclusions:

• Pediatric vision screening is essential but requires standardized protocols.
• Further research and international collaboration are needed to overcome implementation barriers.
• Addressing challenges in low- and medium-income countries is critical for global child eye health.
