Corneal reflex latency in trigeminal nerve lesions
Neurology
|December 1, 1977
Summary
This study establishes normal corneal reflex latency values across age groups. The new technique helps differentiate between afferent and efferent trigeminal nerve lesions.
Area of Science:
- Neuroscience
- Ophthalmology
Background:
- The corneal reflex is a crucial neurological test.
- Assessing trigeminal nerve function is vital for diagnosing neurological disorders.
Purpose of the Study:
- To establish normative data for corneal reflex latency across different age groups.
- To evaluate the utility of corneal reflex latency measurement in differentiating trigeminal nerve lesions.
Main Methods:
- A novel technique was employed to record corneal reflex latency.
- 32 healthy subjects aged 10-80 years were divided into three age cohorts.
- 15 patients with unilateral trigeminal nerve lesions were assessed.
Main Results:
- Normal values for corneal reflex latency were established.
- The technique successfully differentiated between afferent and efferent trigeminal nerve lesions by comparing responses between affected and unaffected sides.
Conclusions:
- Corneal reflex latency measurement provides a reliable method for assessing trigeminal nerve function.
- This technique aids in the clinical diagnosis of specific types of trigeminal nerve damage.
