摘　　要：目的:探讨双眼屈光参差眼的眼轴差值、角膜屈光力差值及屈光度差值的相关性。方法:对61例患者进行双眼屈光度、眼轴、角膜曲率、眼轴/角膜曲率的测量,按双眼等效屈光度差值(双眼屈光度差值)分为两组,分别为双眼屈光度差值≤0.25 D(相似组)和双眼屈光度差值≥1.00 D(参差组)。分别对其进行统计学分析。角膜曲率采用平均K值。结果:相似组中,双眼屈光度差值与双眼眼轴差值、双眼平均K差值正相关(r值分别为0.450、0.370,P均﹤0.05),与双眼眼轴/角膜曲率差值无相关性(P﹥0.05)。双眼眼轴差值与双眼平均K差值正相关(r=0.552,P﹤0.01)。参差组中,双眼屈光度差值与双眼眼轴差值、双眼眼轴/角膜曲率差值正相关(r值分别为0.965、0.962,P均﹤0.01),与双眼平均K差值无相关性(P﹥0.05)。双眼眼轴差值与双眼平均K差值无相关性(P﹥0.05)。结论:眼轴及角膜屈光力是影响双眼屈光参差的重要因素,眼轴及角膜屈光力之间不匹配、不协调而失衡导致屈光参差的产生和进展。眼轴/角膜曲率是监控屈光参差进展的敏感指标。Objective ： To analyze the corretatlon amon~ ul~ efractive power between the two eyes in anisometropia. Methods： The diopter, axial length, corneal refractive power and axial length/corneal radius （AL/CR） were measured in 61 cases. Two groups were created based on the difference of diopter： the difference of diopter 〈~ 0. 25 D （the similar group）, the difference of diopter 〉I 1.00 D （the different group）. The data were analyzed by SPSS statistics software system. Results： In the similar group, the difference of diopter showed positive correlation with the difference of axial length （r = 0. 450, P 〈 0.05 ） and average keratorefractive power （ r = 0. 370, P 〈 0. 05 ）, but showed no correlation with the difference of AL/CR （ P 〉 0.05）. The difference of axial length showed positive correlation with the difference of average keratorefrac- tire power （r -= 0. 552, P 〈 0.01 ）. In the different group, the difference of diopter showed positive correlation with the difference of axial length （r = 0. 965, P 〈 0. 01 ） and AL/CR （r = 0. 962, P 〈 0.01 ）, but showed no correlation with the difference of average keratorefractive power （P 〉 0.05 ）. The difference of axial length showed no correlation with the difference of average keratorefractive power （ P 〉 0.05）. Conclusion： The axial length and keratorefractive power made a great impact on anisometropia. The imbalance of the axial length and keratorefractive power resulted in the production and development of anisometropia. AL/CR is the sensitive index.
