Cranial nerve palsy is one of the common culprits of causing double vision. This is all the more true for people above the age of 60. A person is more prone to cranial nerve palsy if he is suffering from high blood pressure and diabetes. This is the reason why this disease is more commonly known as diabetes palsy. Eventually, though they get better and the problem of double vision disappears.
One weak cranial nerve leads to the weakness of other cranial nerves as well. In case the eyes fail to move together, chances are that the patient will have double or blurred vision. In case the sixth nerve gets affected, side to side double vision is encountered. For the 3rd and 4th nerve disturbance, there could be a vertical double vision. The lack of blood flow causes pain to the eye.
Possible Causes of Cranial Nerve Palsy
Cranial nerve palsy can result from traumatic or congenital factors. They can also result from vascular diseases such as strokes, hypertension, diabetes, and aneurysms. It can also arise out of infections, increased intracranial pressure, migraines, and tumours. A patient's age and clinical findings help a doctor decide the right course of treatment.
There are no particular treatments which can speed up the recovery of cranial nerve palsy. In a case of pupil pain, doctors may prescribe anti-inflammatory drugs such as Motrin and Advil. They key to natural recovery is to ensure that the blood sugar and the blood pressure is diligently controlled. By patching the eyes, the problem of double vision can be resolved. They are typically worn over both the eyes. They are however known to slow down the process of recovery and strain the eye. There is no known exercise to fix this condition. Botulinum injections are sometimes used by doctors to straighten the eyes but the result of such a treatment greatly varies from person to person. Doctors mostly rely on watchful waiting until the phase passes within 6-8 weeks. Pain medications are recommended on a case to case basis.
Managing cranial nerve palsy can be difficult for a working person. It involves many lifestyle changes till the condition fully cares. Some of the suggestions given by an ophthalmologist include resting the eye as long as one can. Reading or working on a computer should be eschewed since it puts great pressure on the eyes. The eye should not be contacted with forehands in case there is too much pain. Other basic hygiene issues include taking the medicine time to time, cleaning the eye with fresh water two to three times a day, putting the eye drops on time as prescribed by the doctor.
