Sixth nerve palsy

Sixth nerve palsy, also known as abducens nerve palsy or lateral rectus palsy, is a neurological condition that affects the abducens nerve, which is responsible for controlling the lateral rectus muscle in the eye. This condition results in the inability to move the eye outward towards the ear (abduction).

Pronunciation

Sixth nerve palsy: /siksθ nɜːv pɔːlzi/

Etymology

The term "sixth nerve palsy" is derived from the fact that the condition affects the sixth cranial nerve, also known as the abducens nerve. The term "palsy" is derived from the Greek word "palsie", meaning "paralysis", which refers to the loss of movement in the affected eye.

Symptoms

The primary symptom of sixth nerve palsy is diplopia (double vision), which occurs when the affected eye cannot turn outward. Other symptoms may include strabismus (misalignment of the eyes), esotropia (inward turning of the eye), and headaches.

Causes

Sixth nerve palsy can be caused by several conditions, including brain tumors, stroke, multiple sclerosis, meningitis, and trauma to the head or face. It can also occur as a complication of diabetes or hypertension.

Treatment

Treatment for sixth nerve palsy depends on the underlying cause. In some cases, the condition may resolve on its own without treatment. In other cases, treatment may involve physical therapy, surgery, or medication to manage symptoms and underlying conditions.
