Testing of visual acuity in infants and young children is discussed in BCSC Section 6, Pediatric Ophthalmology and Strabismus. Refraction should be performed to identify any myopia from axial enlargement and/or astigmatism from corneal irregularity. Decreased vision may be due to significant glaucomatous optic nerve damage, amblyopia, corneal scarring, or other associated ocular disorders (eg, retinal detachment, macular edema, cataract, lens dislocation).
