The progress and prospect of ophthalmological research on cerebral visual impairment in children

Abstract

With the rapid development of global perinatal medicine and neonatal medicine, the survival rate of high-risk neonates (premature, and those who suffer neurologic lesion during or shortly after birth, et al.) improved significantly, however the incidence of cerebral visual impairment (CVI) also rose, which has become the most common cause of visual impairment in children in developed countries. Studies found that visual abnormalities of patients with CVI can be various. Since children's cognition and motor development are inseparable from visual functions, children with CVI are usually characterized by abnormalities in sensory perception, cognition and even movement, other than visual impairment itself. Due to the characteristics of CVI, such as early onset, complex etiology, difficulty in diagnosis and treatment, and involvement with ophthalmology, pediatrics, rehabilitation medicine, genetic epidemiology and other multi-disciplinary content, current domestic research on CVI is limited. From the perspective of ophthalmologist, this paper reviews the progress of ophthalmology diagnosis and treatment in children with CVI in recent years, aiming to have better early recognition and individualized intervention, so as to help pediatrician and rehabilitation physicians to improve survival skills for CVI children and their quality of life.
