What anatomical feature is commonly unchanged in patients with congenital nystagmus?

Understand the Problem

The question is asking which anatomical feature remains unchanged in patients diagnosed with congenital nystagmus. It presents multiple-choice options that suggest different features related to eye anatomy and movement.

More Information

In patients with congenital nystagmus, the retina is commonly unchanged. The condition often originates from abnormalities in other parts of the visual and neurological systems rather than structural issues within the retina.

Tips

A common mistake is assuming the condition involves the retina itself when it often involves neurological pathways or brainstem abnormalities.
