Vision inquiry/screening

Vision inquiry/screening: Vision screening (WHO pocket book)

• Check red reflex for serious ocular diseases such as retinoblastoma and cataracts.
• Corneal light reflex/cover–uncover test & inquiry for strabismus: With the child focusing on a light source, the light reflex on the cornea should be symmetrical. Each eye is then covered in turn, for 2–3 seconds, and then quickly uncovered. The test is abnormal if the uncovered eye “wanders” OR if the covered eye moves when uncovered.
• Check visual acuity at age 3–5 years.
