7. Abnormal Eye Movements: The Misguided Gaze of FRDA
Another notable symptom of Friedreich’s Ataxia is abnormal eye movements, medically termed as nystagmus. Manifesting as involuntary, rapid, and repetitive movements, this symptom can take on different patterns, including side-to-side, up-and-down, or even circular motions.
These irregular eye movements could cause vision-related complications, like blurred or double vision. Besides the obvious physical discomfort, it could also present a psychological challenge, as maintaining eye contact is a vital aspect of human communication.
The emergence of nystagmus in FRDA patients can be attributed to the disruption of the fine balance in the nervous system. The system of nerves and muscles controlling eye movements is intricate and requires precision. Any imbalance in this system, like the one caused by FRDA, could lead to involuntary eye movements.
