Causes and risk factors
There are several causes for abducens nerve palsy. Physical trauma and stroke are common causes. It can also be caused due to infection, inflammation, or tumors of the brain. Abducens nerve palsy can also be congenital. Lifestyle disorders such as diabetes, hypertension, and atherosclerosis are also known causes.
Clinical presentation
The commonest symptom of abducens nerve palsy is diplopia (double vision). Amblyopia is commonly observed in children. Abducens nerve palsy produces a convergent squint (esotropia).
Other neurological symptoms may occur depending upon the location of the lesion. These include ptosis, loss of hearing and weakness of the facial muscles.
Investigations
Ophthalmic examination is carried out to diagnose this condition.
Treatment
Many patients of abducens nerve palsy start improving within a few months. Prism glasses are used to correct the visual defect. If the vision does not improve for several months, surgical correction becomes necessary.
