Forced vergence fixation disparity curves were measured at distance and near on an asymptomatic presbyopic adult population (average age 62.7 +/- 7.0 years, range 51 to 79). Approximately 42% of the 62-subject sample had the same curve types at distance and near (type I-38.4%; type II-3.5%). Different curve types were found in 58.1% of the sample. Detailed breakdown of the curve types is provided. The results are compared with findings published previously on an asymptomatic prepresbyopic sample of the same size. The necessity to establish normative data for fixation disparity curves at distance and near for different vergence states, age groups, and symptomatic subjects is stressed.
对一组无症状的老花成人（平均年龄62.7±7.0岁，范围51至79岁）进行了远距离和近距离的强迫性融合性注视差异曲线测量。在62名受试者的样本中，约42%在远距离和近距离具有相同的曲线类型（I型-38.4%；II型-3.5%）。58.1%的样本中发现了不同的曲线类型。文中提供了曲线类型的详细分类。将结果与之前发表的关于相同规模的无症状早老花样本的研究结果进行了比较。强调了针对不同融合状态、年龄组和有症状受试者建立远距离和近距离注视差异曲线规范数据的必要性。
