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.
