Superior Oblique Palsy
what happens if you dont treat superior oblique palsy
Thank you for this interesting question. Unfortunately, the answer is not as simple as the question.
When I see a patient with a superior oblique palsy (fourth cranial nerve palsy), the first question that I need to answer is "what is the cause of the nerve palsy?"
Some common causes are:
If the underlying cause of the nerve palsy is likely to progress or cause further damage (for example diabetes or a tumor), failure to treat the underlying cause can lead to further complications or even death.
- Congenital (it has been present since birth)
- Trauma induced (such as from a motor vehicle accident)
- Related to blood vessel function (such as with diabetes)
- Due to something creating pressure on the brain (such as a tumor)
Now for actually treating a superior oblique palsy...
The most common treatments include eye muscle surgery, prism glasses, or wearing a patch to eliminate double vision.
What happens if the nerve palsy is not treated? Well this is also a little complicated as it depends on age.
In a young child, failure to treat a superior oblique palsy may result in development of amblyopia or lazy eye (reduced visual function in the eye with the nerve palsy), reduced depth perception, and/or an abnormal head posture.
In an adult, failure to treat a superior oblique palsy may lead to an abnormal head posture and persistence of the signs and symptoms that are currently being experienced (for example: double vision, uncomfortable vision, reduced depth perception, cosmetic misalignment of eyes).
Thank you for visiting NetWellness.
