Anomalous visual processing has been described in individuals with autism spectrum disorder (ASD) but relatively few studies have profiled visual acuity (VA) in this population. The present study describes presenting VA in children with ASD (n = 113) compared to typically developing controls (n = 206) and best corrected visual acuity (BCVA) in a sub-group of children with ASD (n = 29). There was no statistically significant difference in presenting VA between groups (z = -1.75, p = 0.08); ASD group median VA (interquartile range, IQR) -0.05 logMAR (IQR: -0.125 to 0.025 logMAR) and typically developing control group -0.075 logMAR (IQR: -0.150 to -0.025 logMAR). Median BCVA was -0.175 logMAR (IQR: -0.200 to -0.125 logMAR) for the ASD sub-group. Clinicians should not anticipate reduced VA when assessing children with ASD.
自闭症谱系障碍（ASD）患者存在视觉处理异常的情况，但针对该人群的视力（VA）研究相对较少。本研究描述了ASD儿童（n = 113）与正常发育对照儿童（n = 206）的裸眼视力，并报告了ASD儿童亚组（n = 29）的最佳矫正视力（BCVA）。两组之间的裸眼视力无统计学显著差异（z = -1.75，p = 0.08）；ASD组的视力中位数（四分位间距，IQR）为-0.05 logMAR（IQR：-0.125至0.025 logMAR），正常发育对照组为-0.075 logMAR（IQR：-0.150至-0.025 logMAR）。ASD亚组的最佳矫正视力中位数为-0.175 logMAR（IQR：-0.200至-0.125 logMAR）。临床医生在评估ASD儿童时不应预期其视力会降低。
