BACKGROUND
Due to accommodation-vergence cross-link we can expect that presbyopia will affect vergence as well. From investigations of cross-link as function of age one may assess strain of visual system due to presbyopia. Furthermore, this observation will give hints on innervation of ciliary muscle.
MATERIAL AND METHOD
Vergence is assessed as function of stimulus of accommodation in 27 subjects (24-65 years).
RESULTS
Presbyops tend to be exophoric for near vision. Vergence is linked to accommodation by means of a quadratic polynome rather than by a linear function.
CONCLUSIONS
We may expect, that missing vergence strains visual system of presbyops. Results support Hess-Gullstrand theory of presbyopia and indicate a loss of innervation of ciliary muscle with increasing age.
背景
由于调节性集合交叉联系，我们可以预期老花眼也会影响集合。通过研究交叉联系随年龄的变化，人们可以评估老花眼导致的视觉系统紧张程度。此外，这一观察结果将为睫状肌的神经支配提供线索。
材料与方法
对27名受试者（24 - 65岁）的集合功能随调节刺激的变化进行评估。
结果
老花眼患者在近视力时往往有外隐斜。集合与调节通过二次多项式而非线性函数相关联。
结论
我们可以预期，集合功能缺失会使老花眼患者的视觉系统紧张。研究结果支持了老花眼的赫斯 - 古尔斯特兰德理论，并表明随着年龄增长睫状肌神经支配丧失。
