Ocular migraine (or absolute scotoma) is an acute disturbance of vision associated with disorder of the blood supply to certain areas of the brain (pathways to the optic nerve, occipital cortex region, etc.). In this pathology, patients lost the picture on the same areas of the field of vision in both eyes and flicker appears.
Causes of eye migraines
The main cause of this disease is the pathological changes in the blood vessels of the brain. Such changes occur primarily in the autonomic disorders, so vegetative-vascular dystonia is quite often accompanied by atrial scotoma. Factors that provoke the emergence of ocular migraine are:
- Fatigue (associated with chronic lack of sleep, hard physical or mental work).
- Mental overexertion.
- Hormonal changes.
- Smoking, alcohol abuse.
- Hypoxia (being in a stuffy room, public transport).
- The change in the weather.
At the beginning of the attack, patients notice the loss of a small area of the visual field, often in the Central region and then in both eyes. At this stage the image becomes blurred or even disappears, there is a shimmering zig-zag area. The size of the scotoma may gradually increase, she can move from the center to the periphery. After about 20 – 30 minutes after the occurrence of visual disorders there is a severe headache, sometimes with nausea and vomiting. Therefore, physicians consider atrial the scotoma as a visual aura of classical migraine. In some patients, ocular migraines are never accompanied by headache disappears within half an hour after the attack.
