Abducens palsy
Abducens Palsy
Abducens palsy (pronounced: ab-DOO-senz PAL-zee), also known as sixth nerve palsy or lateral rectus palsy, is a neurological condition that impairs the function of the Abducens nerve, one of the cranial nerves responsible for eye movement.
Etymology
The term "Abducens palsy" is derived from the Latin word "abducens" which means "leading away", and the Greek word "palsy" which means "paralysis". This refers to the paralysis or weakness of the muscle that leads the eye away from the nose.
Symptoms
The primary symptom of Abducens palsy is double vision, which is caused by the inability of the affected eye to turn outward. Other symptoms may include strabismus (misalignment of the eyes), esotropia (inward turning of the eye), and difficulty with lateral gaze.
Causes
Abducens palsy can be caused by several factors including brain tumors, strokes, infections, trauma, or inflammation in the brain. It can also be a complication of certain medical conditions such as diabetes, multiple sclerosis, or Guillain-Barre syndrome.
Diagnosis
Diagnosis of Abducens palsy involves a thorough neurological examination, including tests of eye movement and alignment. Imaging tests such as MRI or CT scan may also be used to identify any underlying conditions causing the palsy.
Treatment
Treatment for Abducens palsy focuses on addressing the underlying cause. This may involve medication, surgery, or other treatments depending on the cause. In some cases, physical therapy may be recommended to help improve eye coordination and reduce symptoms.
