摘　　要：目的了解先天性白内障患者早期眼球生物学参数发育特点。方法回顾性病例系列研究。选取2016年6月至2020年6月在温州医科大学附属眼视光医院杭州院区诊断为先天性白内障的169例3岁以下患者的眼轴长度、角膜屈光力、前房深度、角膜厚度等生物学测量资料,分3个年龄段进行分析。1~6月龄、7~12月龄、13~36月龄3个年龄段的患者分别有87、41、41例;双眼患者108例,单眼患者61例;晶状体非全混型患者84例,全混型患者85例。双眼患者选右眼数据,生物学参数比较采用独立样本t检验及配对t检验,Pearson相关检验分析月龄与生物学参数的关系。结果1~6月龄双眼患者患眼眼轴长度为(17.59±1.19)mm,小于单眼患者患眼[(18.18±1.34)mm],单眼患者患眼眼轴长度小于健眼[(19.01±0.93)mm];7~12月龄单眼患者患眼眼轴长度[(19.89±0.74)mm]小于健眼[(20.48±0.43)mm],差异均有统计学意义(t=-2.06、-5.62、-3.47,均P<0.05)。1~6月龄晶状体非全混型患者患眼眼轴长度小于全混型患者[(17.43±1.14)mm与(18.06±1.29)mm比较:t=-2.38,P=0.020]。非全混型单眼患者患眼与健眼眼轴长度差值与月龄呈显著正相关(r=0.53,P=0.001)。7~12月龄单眼患者患眼角膜屈光力小于健眼[(42.41±1.82)D与(43.19±1.96)D比较:t=-2.29,P=0.038],而13~36月龄单眼患者患眼角膜屈光力大于健眼[(43.36±2.32)D与(42.55±1.88)D比较:t=2.17,P=0.043]。1~6月龄单眼患者患眼前房深度小于健眼[(2.44±0.37)mm与(2.58±0.33)mm比较:t=-2.08,P=0.048]。1~6月龄和7~12月龄单眼患者患眼角膜厚度均大于健眼[(555.26±46.95)μm与(541.85±40.78)μm比较:t=3.82,P=0.001;(542.93±27.63)μm与(530.93±30.36)μm比较:t=2.26,P=0.040]。结论先天性白内障可能影响早期眼轴长度、角膜屈光力、前房深度和角膜厚度的发育。晶状体混浊程度可能影响早期眼轴长度,6月龄前非全混型白内障患眼眼轴长度较全混型白内障患眼更短,此后非全混�Objective To understand the developmental characteristics of early ocular biological parameters in patients with congenital cataract.Methods Retrospective case series study.The ocular biometry data such as the axial length,corneal curvature,anterior chamber depth and central corneal thickness of 169 patients under 3 years old who were diagnosed with congenital cataract in Eye Hospital of Wenzhou Medical University(Hangzhou Branch)from June 2016 to June 2020 were reviewed,and they were analyzed by 3 age groups.There were 87,41,and 41 patients in three age groups,1 to 6 months,7 to 12 months,and 13 to 36 months,respectively;108 patients with bilateral affected eyes and 61 patients with unilateral affected eyes were included;84 patients with partial opacity lens and 85 patients with total opacity lens were included.The right eyes of the patients with bilateral congenital cataract were selected for analysis.Statistical analysis of ocular biological parameters between groups was performed using the independent samples t-test and paired samples t-test.Statistical analysis of the relationship between age in months and biological parameters was performed using the Pearson′s correlation test.Results The axial length at the age of 1 to 6 months in the affected eyes of patients with bilateral cataract was(17.59±1.19)mm,it was shorter than the affected eyes of patients with unilateral cataract[(18.18±1.34)mm],and the axial length in the affected eyes of patients with unilateral cataract were shorter than the healthy eyes[(19.01±0.93)mm].At the age of 7 to 12 months,the axial length in the affected eyes of patients with unilateral cataract[(19.89±0.74)mm]was shorter than the healthy eyes[(20.48±0.43)mm].The differences were statistically significant(t=-2.06,-5.62,-3.47,all P<0.05).The axial length in the affected eyes with partial opacity at the age of 1 to 6 months was shorter than those with total opacity[(17.43±1.14)mm vs.(18.06±1.29)mm;t=-2.38,P=0.020].The difference in axial length(affected eyes vs.healthy eyes)
