1.Healthy children should have their first eye screening 28-30 days after birth, and stage eye screening and vision screening at the same time as health examinations at 3, 6 and 12 months of age and 2, 3, 4, 5 and 6 years of age, respectively. 2. Newborns with high-risk factors for eye disease should be examined by an ophthalmologist as early as possible after birth. High-risk factors for neonatal eye disease include: (1) Neonatal intensive care unit stay of more than 7 days and a history of continuous oxygen (high concentration). (2) Clinical family history of hereditary eye disease or suspected syndromes related to eye disease, such as congenital cataract, congenital glaucoma, retinoblastoma, congenital microphthalmia, nystagmus, etc. (3) Intrauterine infections caused by cytomegalovirus, rubella virus, herpes virus, syphilis or toxoplasma protozoa (Toxoplasma gondii), etc. (4) Craniofacial morphologic deformities, large facial hemangiomas, or ectropion of the eyeballs during crying. (5) Difficult birth, instrument-assisted birth. (6) persistent ocular lacrimation, a large amount of discharge. (3) Premature and low birth weight infants with birth weight <2000g should be screened by an ophthalmologist for the first time for fundus pathology at 4-6 weeks after birth or 32 weeks of corrected gestational age.
