Abstract: Objective To evaluate the differences between near visual acuity and distance visual acuity in the children with amblyopia. Design Retrospective case series. Participants Eighty-one children (139 eyes) with amblyopia. Method The refraction of eighty-one children was corrected. The near visual acuity and distance visual acuity were measured by Standard Logarithm Distance Visual Acuity Chart and Standard Logarithm Near Visual Acuity Chart. The patients were grouped with different causes, different age, and different refraction.  Main Outcome Measures The mean near visual acuity and distance visual acuity. Results The mean near visual acuity in ametropic, anisometropic and strabismus amblyopia were 0.48±0.27，0.47±0.28 and 0.45±0.30, respectively; and the mean distance visual acuity were 0.46±0.22, 0.40±0.20 and 0.43±0.30, respectively (all P＞0.05). The mean near visual acuity in groups age 3~≤5, >5~≤7 and >7~12 were 0.41±0.23，0.56±0.29 and 0.46±0.31, respectively; and the mean distance visual acuity were 0.39±0.18, 0.52±0.22 and 0.42±0.23, respectively (all P＞0.05). The mean near visual acuity in group ≤+4.00 D and ＞+4.00 D were 0.45±0.26 and 0.48±0.28, respectively; and the mean distance visual acuity were 0.40±0.30 and 0.46±0.21, respectively (all P＞0.05). Conclusion There is no significant difference between near visual acuity and distance visual acuity in the patients with different causes, ages, and refrections amblyopia. （Ophthalmol CHN， 2013, 22:  266-268）
