Visual disorders are widespread. A visual disorder is a temporary or persistent pathological impairment of the visual apparatus. It can be manifested by blackness, loss of parts of the visual field, double vision or flickering areas, flashes, bright spots, distortions or even blurred and hazy vision. The causes can be manifold and range from harmless to life-threatening.
Possible causes and indications of specific diseases
Apart from visual defects such as being near-sighted, far-sighted or presbyopia, which usually develop over a long period of time, sudden disturbances or worsening vision can be indications of serious neurological diseases. Visual disturbances are connected with many disorders, including circulatory disturbances affecting the brain, brain hemorrhages, brain tumors, multiple sclerosis and others. When migraine occurs with aura, this can also lead to a deterioration of vision.
In order to determine the exact causes of visual disturbances, an examination by an ophthalmologist is often necessary. In many cases, however, the symptoms should be clarified by a neurologist.
