AIM
To study the relationship between ocular parameters and amplitude of accommodation (AA) in the peri-presbyopic age group (35-50 years).
MATERIALS AND METHODS
Three hundred and sixteen right eyes of consecutive patients in the age group 35-50 years, who attended our outpatient clinic, were studied. Emmetropes, hypermetropes and myopes with best-corrected visual acuity of 20/20, J1 in both eyes were included. The AA was calculated by measuring the near point of accommodation. The axial length (AL), central anterior chamber depth (CACD) and lens thickness (LT) were also measured.
RESULTS
There was moderate correlation (Pearson's correlation coefficient r = 0.56) between AL and AA as well as between CACD and AA (r = 0.53) in myopes in the age group 35-39 years. In the other age groups and the groups taken as a whole, there was no correlation. In hypermetropes and emmetropes, there was no correlation between AA and the above ocular parameters. No significant correlation existed between LT and AA across different age groups and refractive errors.
CONCLUSION
There was no significant correlation between AA and ocular parameters like anterior chamber depth, AL and LT.
目的
研究远视前期（35-50 岁）人群眼参数与调节幅度（AA）的关系。
材料与方法
对 316 例连续就诊于我院门诊的 35-50 岁患者的 316 只右眼进行研究。纳入标准：正视眼、远视眼和近视眼，最佳矫正视力为 20/20，双眼 J1 。通过测量近点调节力来计算 AA。同时测量眼轴长度（AL）、中央前房深度（CACD）和晶状体厚度（LT）。
结果
35-39 岁的近视人群中，AL 与 AA 之间以及 CACD 与 AA 之间存在中度相关（Pearson 相关系数 r = 0.56）。在其他年龄组和总体人群中，均无相关性。远视眼和正视眼中，AA 与上述眼部参数之间均无相关性。不同年龄组和不同屈光度人群中，LT 与 AA 之间无显著相关性。
结论
AA 与前房深度、AL 和 LT 等眼部参数之间无显著相关性。
