American Journal of Ophthalmology
|March 1, 1978
Summary
Friedreich's ataxia patients exhibit abnormal eye movements called square wave jerks. These involuntary saccades are a potential indicator of chronic cerebellar dysfunction in this neurodegenerative condition.
Area of Science:
- Neuro-ophthalmology
- Genetics
- Neurology
Background:
- Friedreich's ataxia is a rare inherited disease.
- It primarily affects the nervous system, leading to progressive damage.
- Ocular motor abnormalities are increasingly recognized in Friedreich's ataxia.
