摘要

马多克斯棒是斜视评估的主要工具。然而，它的光学机制令人困惑。正交线焦点是如何形成的？令人惊讶的是，很少有文本提供解释，而那些文本要么提供的细节不足，要么包含误导性信息，要么难以理解。有一个普遍的误解，即需要多个圆柱体才能出现正交线焦点。然而，这是不真实的；马多克斯自己第一次描述这种现象时只用了一个圆柱体。在此，我们回顾了在文本样本中提供的光学解释，并提供了一个准确的解释，使用双面原理的像散折射。

The Maddox rod: Revisiting the optics.

The Maddox rod is a staple in the assessment of strabismus. However, its optics mechanism is puzzling. How is it that an orthogonal line focus is formed? Surprisingly, few texts offer an explanation and those that do either provide insufficient detail, contain misleading information or are difficult to follow. There is a prevalent misconception that multiple cylinders are required for the orthogonal line focus to appear. However, this is untrue; Maddox himself only used a single cylinder when he first described the phenomenon. Herein, we review the optics explanations provided in a sample of texts and offer an accurate explanation using the biplanar principle of astigmatic refraction.
