[Chinese expert consensus on the visual acuity testing for infants and preverbal children (2023)]
Insights
Early screening for visual acuity in infants and children is crucial to prevent permanent vision impairment. This consensus promotes standardized testing methods for early detection and intervention.
Area of Science:
- Ophthalmology
- Pediatric ophthalmology
- Vision science
Context:
- Abnormal visual experiences in early childhood can cause permanent vision loss without prompt intervention.
- Evaluating visual acuity in infants and preverbal children is challenging due to communication barriers and lack of standardized methods.
- Early detection of visual abnormalities is critical for preventing long-term visual impairment.
Purpose:
- To establish standardized visual acuity testing protocols for infants and preverbal children.
- To provide guidelines for screening and follow-up examinations in pediatric ophthalmology.
- To address the clinical need for reliable visual assessment in young children with suspected visual abnormalities.
Summary:
- A consensus statement has been developed by leading Chinese ophthalmology associations.
- The consensus is based on evidence-based research to standardize visual acuity testing.
- It aims to improve early detection and management of visual impairments in children.
Impact:
- Promotes standardized visual acuity testing for infants and preverbal children.
- Facilitates early screening and timely intervention, potentially preventing permanent visual impairment.
- Enhances the quality of pediatric eye care through evidence-based guidelines.
Abstract:
Abnormal visual experience in the first 3 years of life may lead to permanent visual impairment without early screening and timely intervention. It is of great clinical significance to evaluate the visual acuity of infants and preverbal children with suspected visual abnormality. However, the evaluation is difficult due to the inability of these children to express their complaints and the lack of unified standards. In order to promote the standardization of the visual acuity testing in infants and preverbal children, including the screening and follow-up examinations, a consensus has been reached by the Chinese Association for Pediatric Ophthalmology and Strabismus along with the Pediatric Ophthalmology and Strabismus Group of Chinese Ophthalmologist Association, based on the research results of evidence-based medicine.
