How effective is treatment for unilateral visual impairment detected by preschool vision screening?
Multicentre randomised controlled trial.
Glasses plus patch treatment slightly but significantly improved visual acuity (both uncorrected and best corrected) compared with no treatment in children with mild to moderate unilateral visual impairment at 52 weeks (see Table 1; see notes). Glasses alone modestly improved best corrected visual acuity compared with no treatment; however there was no significant difference in uncorrected visual acuity between these groups.
Treatment with glasses alone or in combination with patches can modestly improve visual acuity in children with mild to moderate unilateral visual impairment, compared with no treatment.Le texte complet de cet article est disponible en PDF.
