目的探讨弱视与适应能力的关系。开场大精工双目自折射镜已成为自动测量静态调节的黄金标准。我们测量了52名3至14岁儿童的调节振幅，使用大精工自动折射。孩子们戴着眼镜进行这项测试，这是根据一位儿童眼科医生进行的单眼麻痹性屈光检查开出的处方。9只眼（5例）无读数。在1/3米处利用完全调节力进行校正的正常调节是3D的，假设没有调节滞后，并且会从大精工自动折射镜产生−3.00D的读数。没有任何调节，读数应为0.00D。随着敏锐度的恶化，宽松度逐渐下降。我们的结果表明，弱视的眼睛不适应以及非弱视的眼睛。由于调节幅度不是主观的，它可能是弱视回归的一个比视力更敏感的指标。大精工自动折射镜可能被证明是一个有用的工具来监测弱视患者的进展。
To evaluate the relationship between amblyopia and accommodative ability. The open-field Grand Seiko binocular autorefractor has become the gold standard for automated measurement of static accommodation. We measured the accommodation amplitudes in 52 children ages 3 to 14 years employing the Grand Seiko auto refractor. Children wore their glasses for this test, which was prescribed based on a cycloplegic refraction performed by one pediatric ophthalmologist. No readings could be obtained for 9 eyes (5 patients). Normal accommodation with correction utilizing full accommodative effort at 1/3 meter is 3D assuming no accommodative lag, and would generate a reading of −3.00D from the Grand Seiko auto refractor. Lack of any accommodative should give a reading of 0.00D. Accommodative gradually declined as the acuity worsened. Our results suggest that amblyopic eyes do not accommodate as well as non-amblyopic eyes. Because accommodation amplitude is not subjective it may be a more sensitive indicator of regression of amblyopia than visual acuity. The Grand Seiko autorefractor could prove to be a useful tool to monitor the progress of patients with amblyopia.
