目的比较光相干生物测量仪(IOL Master)和超声生物测量仪(接触式A型超声)对白内障合并视网膜脱离(累及黄斑区)患者眼轴长度(axial Length,AL)的测量结果,得出更加准确的AL,以进一步提高这类患者术后的视力.方法临床病例对照研究.对2009年5月至2012年10月在深圳市眼科医院就诊的35例35只眼(均为视网膜脱离累及到黄斑区的患者)分别用IOL Master和接触式A超进行10次连续测量AL,并与B超粗测的AL进行对比.结果 IOL Master和接触式A超、B超测量AL(均值)分别为:(21.42±0.41) mm、(25.71±0.45) mm、(25.97±0.65) mm. IOL Master和接触式A超测量的AL差异有统计学意义(t=-3.521;P=0.015).接触式A超和B超测量的AL差异无统计学意义(f =-1.213; P=0.313).结论对于白内障合并视网膜脱离(累及黄斑区)眼,IOL Master测量的AL的可重复性和准确性均不再优于接触式A超.现阶段两种检查方法要针对患者的情况相结合使用,并联合B超以加强测量的精确度.

Objective To compare the axial length (AL) measured by IOL Master and contact A-Scan in patients with cataract combined with retina detachment (RD) implicated with macula lutea,to obtain the accurate measurements of axial length to improve the vision of cataract patients.Methods Thirty-five eyes (35 patients) with cataract combined with RD were enrolled in this study.AL was measured with IOL Master and contact A-Scan.And the measurements were compared with that by b-mode ultrasound.Results Mean ALS by IOL Master and contact A-Scan and b-mode ultrasound were (20.42±0.41)mm,(25.16±0.45)mm,(24.97±0.65)mm.The difference between IOL Master and contact A-Scan was meaningful statistically (t =-3.521; P =0.015).Conclusions The results showed that measurements for AL are no longer precise and high reproducibility with IOL Master.
