Overview
Reduced vision from disrupted visual development in early childhood, most often driven by strabismus, refractive asymmetry or form deprivation. It is typically found on testing rather than reported, since a child may not volunteer symptoms: the finding is a two-line interocular acuity difference or acuity below the age norm, often with fixation preference or reduced stereopsis. Outcomes depend heavily on how early it is detected.
Recognition
Symptoms: what patients report
- Reduced vision noticed on school screening or routine testing.
- Two-line interocular visual acuity difference or acuity worse than expected for age.
- Child may not report symptoms directly.
- Reading or attention difficulties may be reported by parents or teachers.
Signs: what the examination shows
- Reduced monocular visual acuity, often unilateral, or a two-line interocular acuity difference.
- Fixation preference or inter-eye visual asymmetry.
- Suppression or reduced stereopsis on binocular testing.
- Associated strabismus or significant refractive asymmetry may be present.
