What does it mean?

Any changes that affect only one eye, are a manifestation of a disease of the optic nerve. They will take effect either in looks in the visual field (scotoma), narrowing of the visual field, or the patient may go blind in one eye completely. Causes that have such a condition most often to blame, not many. Primarily behind this vascular circulatory disorders. Here is a possibility to atherosclerotic changes in large vessels. Vascular supply to the optic nerve from several river basins, but the dominant supply of the internal carotid artery branch (internal carotid artery), which are often found atherosclerotic plaques that cause a bottleneck. This is reflected in the reduction of blood supply to the area that this large artery supplies, which among other things target optic nerve.Another option, which causes sudden blindness in one eye embolism is one of the ophthalmic veins (veins). Embolus (embolus, blood clot), you can get here from anywhere in the large circulation and cause sudden obliteration (blockage) of blood drainage from the eye. Sometimes mentioned this variant occurs in such a way that blindness does not occur immediately, but develop progressive change. In such stage, it is an important early diagnosis. The problem is that people seldom attach importance to these changes and do not seek a doctor.

Blindness in one eye can also result from eye injuries or tumor process in one eye, but this is often not the most frequent reason for unilateral (monocular blindness).

What to do?

If arteries are affected by atherosclerosis, the changes are reflected in other organs than the eye.Atherosclerosis in an advanced stage and with multivessel disease in the body are difficult to treat.Blindness caused by this disease can be both permanent and temporary – it depends on the degree of narrowing of the afferent vessels. If blindness arises after embolization venous circulation in the eye, so radiation therapy using vascular laser to avoid further embolization and prevent greater ocular.

In short at the end

If you have suffered an injury and you do not see in one eye, and a visit to the doctor checks the obvious choice, as well as for people who suddenly become blind in one eye, so the risk is small understatement. But if the changes are subtle, even a minor forays into the field of view, this may not be paid by the patient as much attention as it deserved.

Eye disease is often not associated only with vision, reflected in here much more serious, so it is advisable not to underestimate warning signals.
