The doctor named four signs of eye problems that require a visit to a neurologist

Sometimes the human brain sends signals of distress through the eyes. Some problems with the latter may be a sign of the need to visit a neurologist, not an ophthalmologist, Dr. Robert Leiman, who heads the American Optometric Association, is confident.

Sometimes a person notices a loss of clarity of vision, objects seem blurry to him. The whole matter can be in dry air, excessive load on the eyes. However, sometimes the reasons are much more serious. For example, the blurriness is due to the dysfunction of binocular vision, which can lead to it due to systemic diseases or a brain tumor. Sometimes multiple sclerosis provokes the condition, because it leads to inflammation, which is caused by optic neuritis. In this case, it can be painful to even move your eyes easily.

Double vision can indicate a craniocerebral injury. Then the person has problems to follow the object with his eyes, there is also an increased sensitivity to light. Leyman recommends contacting a specialist even if the injury seems minor. Some actually suffer a concussion on their feet, which can have serious consequences. In addition, even minor injuries can have a negative impact on vision.

If vision has dropped sharply, the cause may be serious. One of these is retinal detachment. The problem is solved, but the sooner you start fighting it, the better the prognosis. It happens that the symptom is caused by a brain tumor. This puts pressure on the optic nerve, so there is a risk of blindness. Vision declines gradually, clarity is lost, diplopia is observed, a blind spot appears, the size of which continues to grow.

Decreasing peripheral vision can warn of the onset of Alzheimer's disease. And, usually, physically, everything is normal with the eyes of a person. The brain of a dementia patient loses the ability to fully process visual information. That is, the eyes see everything, but the main body of the central nervous system cannot decipher the incoming data. It is as if the individual begins to look at the world through a tube, seeing only something in front of him.
