Many causes are preventable or treatable with timely screening.","answer_md":"*A child's visual system is built across pregnancy, birth and the first years — and contributing factors track that timeline.*\n\n## In short\nEarly-childhood visual impairment is multifactorial, spanning **prenatal, perinatal and postnatal** influences. The dominant contributors in the Indian context include retinopathy of prematurity, perinatal hypoxic-ischaemic injury, congenital and developmental anomalies (cataract, glaucoma, optic nerve hypoplasia), genetic and metabolic conditions, intrauterine (TORCH) infections, and avoidable causes such as vitamin A deficiency and uncorrected refractive error. Cerebral/cortical visual impairment is now a leading cause in children with neurological comorbidity.\n\n## The contributing factors\n**Prenatal —** genetic and chromosomal syndromes; inherited retinal dystrophies; structural anomalies (microphthalmia, coloboma, optic nerve hypoplasia); intrauterine TORCH infections (rubella, CMV, toxoplasmosis); maternal substance exposure.\n\n**Perinatal —** prematurity and low birth weight driving **retinopathy of prematurity (ROP)**; hypoxic-ischaemic encephalopathy and neonatal hypoglycaemia producing **cortical/cerebral visual impairment (CVI)**; birth trauma.\n\n**Postnatal —** vitamin A deficiency and measles (corneal blinding, still relevant in under-served populations); paediatric cataract and glaucoma; trauma; uncorrected high refractive error and untreated amblyopia; CNS infection (meningitis).\n\nA substantial share is **preventable or treatable** with timely ROP screening, newborn red-reflex examination, refractive correction and amblyopia therapy — making early case-finding the highest-yield intervention.\n\n## The Pinnacle way\nAny diagnosis and a clinical AbilityScore® are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from a form or screen. We co-manage functional vision and developmental impact alongside ophthalmology. See [Visual Impairment](/visual-impairment), our [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) pathway and [how the AbilityScore® works](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nWHO classification of visual functioning (ICD-11 9D90); WHO guidance on childhood blindness and avoidable causes; AAP/AAPOS recommendations on ROP screening and red-reflex testing.\n\n**Next step —** For children with neurological or developmental comorbidity, [partner with Pinnacle](/partner) for integrated functional-vision and developmental support.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare
