Visual impairment (ICD-11 9D90) is reduced, non-correctable visual function graded by best-corrected acuity and field in the better eye. In early childhood, behavioural testing leads the grade; cortical/cerebral causes can co-exist with a normal eye exam. Early detection drives motor, language and cognitive support.

*The first clinician to notice a child not fixing, following or reaching for light is often the one who changes that child's trajectory.*

## In short
Visual impairment (ICD-11 **9D90**) describes reduced visual function that is not fully correctable by refraction, ranging from mild impairment to blindness, graded clinically by distance and near visual acuity in the better eye with best correction. In early childhood it matters not only as an ophthalmic finding but as a driver of delay across motor, communication, social and cognitive domains — the visual channel that ordinarily scaffolds early learning is attenuated.

## The science, briefly
ICD-11 categorises severity (mild, moderate, severe, blindness) on standardised acuity and visual-field criteria. In infants and toddlers, acuity testing is necessarily behavioural — fixation and following, preferential-looking, optokinetic responses — so the **functional** picture often leads the formal grade. Watch for absent fix-and-follow by 3 months, no visual reaching by 5–6 months, persistent nystagmus, roving eye movements, photophobia, leukocoria, or a regressing visual interest. Crucially, cortical/cerebral visual impairment is a leading paediatric cause and may co-exist with normal ocular structure, so a normal eye exam does not exclude it. Early identification triggers vision-stimulation, mobility and developmental support that materially alters outcomes.

## The Pinnacle way
At Pinnacle Blooms Network, any diagnosis and a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) are formed only at a centre, under qualified clinician care — never from an app or a form. Suspected [visual impairment](/visual-impairment) warrants prompt ophthalmology and, in parallel, functional developmental and [occupational-therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) support.

## Trusted sources
WHO ICD-11 (entity 9D90); WHO and AAP guidance on paediatric vision screening and early detection.

**Next step —** Refer a child with suspected reduced visual function for combined ophthalmic and developmental assessment at your nearest [Pinnacle centre](/visual-impairment).

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
