摘　　要：目的:探讨学龄弱视儿童眼散光的主要类型、分布特征以及与年龄、弱视类型的关系。方法:选取广西视光中心就诊的6～12岁学龄弱视散光儿童1 102例(1 843眼),在睫状肌麻痹条件下采用视网膜检影法确定散光状态,描述弱视儿童散光的主要类型、分布特征以及与年龄、弱视类型的关系。结果:①1 843只散光眼中,散光度以0.50～2.00 D为主(66.9%),散光类型以远视性散光为主(62.6%),散光轴向以顺规散光为主(88.8%);不同散光性质的散光度和散光轴向差异有统计学意义(P<0.001)。②不同年龄的散光类型、散光度差异均有统计学意义(P<0.05),但不同年龄的散光轴向差异无统计学意义(P>0.05);随着年龄增长,复合性远视散光所占比例呈增长趋势,单纯性远视散光呈减少趋势。③屈光不正性弱视占70.0%,屈光参差性弱视占24.2%,斜视性弱视占5.8%。不同类型弱视的弱视眼的散光度、散光性质差异有统计学意义(P<0.05),但散光轴向差异无统计学意义(P>0.05)。结论:远视性散光、低中度散光、顺规散光是学龄期弱视儿童散光的主要类型,年龄、弱视类型与散光关系密切,应及时矫正学龄期儿童眼散光。Objective：To investigate the main types,distribution characteristic and its relationship with age or best corrected visual acuity（BCVA） of astigmatism in school-aged amblyopic children. Methods：1 102 amblyopia children（1 843 eyes） with astigmatism in age from 6 to 12 years were studied.The astigmatism status of amblyopic eyes were measured by retinoscopy optometries under the ciliary muscles paralysed.The main types,distribution characteristic and its relationship with age or BCVA of astigmatism in amblyopic children were described. Results：① In 1 843 astigmatism eyes,the 0.50~2.00 D group,hyperopia astigmatism group and astigmatism axial followed the rules were the mainly group,which accounted for 66.9%,62.6% and 88.8% respectively;The distribution of astigmatism degree and astigmatism axial in different astigmatism type were statistically different（P0.001）.② The distribution of astigmatism type and astigmatism degree in different age were statistically different（P0.05）,however,the distribution of astigmatism axial in different age had no statistically different（P0.05）;the proportion of compound hyperopia astigmatism increased with age,while simple hyperopia astigmatism becomed lower.③The proportion of ametropic amblyopia,anisometropic amblyopia and strabismic amblyopia were 70.0%,24.2% and 5.8% respectively;The distribution of astigmatism degree,astigmatism type in different kinds of amblyopic eyes had statistically different（P0.05）,while the distribution of astigmatism axial in different kinds of amblyopic eyes had no statistically different（P0.05）. Conclusion：Hyperopia astigmatism,mild and moderate astigmatism and astigmatism axial followed the rules are the main types in school-aged amblyopic children with astigmatism.The age and amblyopia degree have closely relationship with astigmatism.It is necessary to timely correct astigmatism in school-aged children.
