Damage to the abducens nerve of the eye is one of the ophthalmological pathologies that have much in common with neurological disorders. With this disease, the movements of the eyeball are distorted. It often happens that it does not move, especially when you need to look to the right. Let's tell you more about this disease and its treatment.

What could be the consequences?
Diagnosed neuropathy of the peroneal nerve is a serious disease that requires timely treatment. Otherwise, the patient may lose his ability to work and become disabled. Complications of this disease are paresis, which reduces the strength capabilities of the limb. Possible complications and consequences can be prevented if, when the first signs of the disease occur, you undergo a professional examination in a hospital setting and a prescribed course of treatment followed by rehabilitation.

Symptoms of pathology
The disorders that occur in the human body with this pathology affect various areas. The extent of optic nerve damage may also vary from patient to patient. Much depends on the immune system and the general condition of the body. Sometimes it happens that neuropathy affects the oculomotor nerve completely. In some cases, a partial disruption of its functions occurs. Therefore, it is very important for the doctor to analyze in detail the symptoms, which can be varied. The main signs of the disease include:
- drooping eyelid;
- pain in the eyes;
- immobility of the eyeball;
- decreased visual acuity;
- dilated pupils;
- diplopia.
A common consequence of abducens neuropathy is heterotropia. Typically, the patient develops convergent strabismus. More often this occurs in advanced forms of the pathology. Some people complain of high blood pressure, which is often due to problems with the brain. Headaches are another common symptom of this disease. It often happens that patients do not pay attention to the malaise and associate it with prolonged visual work.
