Human sensory organs include vision, hearing, touch, smell and taste, which receive various information from nature to enable human beings to survive, live, work and learn, among which the information received by visual organs accounts for more than 80%. Children 0-3 years old is the critical period of visual development, and many eye diseases that endanger vision and even life can occur during this period, such as retinopathy of prematurity, permanent primitive vitreous hyperplasia, familial exudative vitreoretinopathy, congenital cataract, congenital glaucoma, infectious eye diseases, optic nerve dysplasia, retinoblastoma and so on. However, due to the inability of children to accurately express their eye discomfort and poor cooperation, many eye diseases are not detected and treated in time, resulting in lifelong visual disability or even life-threatening. Therefore, it is important to strengthen the monitoring of eye diseases in infants and children. The RetCam digital photographic pediatric retinal examination system is a fast, safe and effective eye examination instrument, which can observe and record the retinal images of infants and young children in a clear, true and objective way, which is intuitive and can be saved, and the pictures recorded in multiple examinations and treatments can be compared and analyzed, which can help to follow up the children, record the results of the medical treatment, and consult with the doctor remotely. It has been used for the examination and diagnosis of pediatric intraocular tumors, various fundus diseases, optic nerve dysplasia and other eye diseases at home and abroad. It is the most effective method for the early detection and diagnosis of pediatric fundus diseases, and the RetCam camera has a shooting range of up to 130 degrees, which not only can clearly observe the important parts of the fundus (macula, optic papilla), but also can clearly take pictures of the peripheral fundus without the need of scleral apex pressure, thus reducing the stimulation of the examination for the newborns, and avoiding the occurrence of the oculocardiac reflex and other undesirable reactions. Our department started to screen for retinopathy of prematurity in 1999, and has screened nearly 10,000 cases of preterm babies so far, and has rich experience in the diagnosis and treatment of pediatric eye diseases. With the RetCam pediatric retinal examination system, we have expanded the screening of preterm infants to include the entire population of newborns, infants and toddlers, and we have been conducting long-term screening of newborns, infants and toddlers for eye diseases. We are doing our best to reduce childhood blindness.
