Retinal migraine symptoms

Ciliated scotoma is difficult to confuse with other ophthalmic diseases. With retinal form, provoked by abnormal relaxation of the posterior cerebral artery, the patient is worried about:

• defects arising in the field of view – bright flashes, flickering, dark spots, and streaks that can merge 
• the gradual total decrease in visual acuity
• the appearance of phosphenes (visual images) in the “blind” areas of the visual field and along its periphery;
• increased sensitivity to light, sounds, touch. They increase the pain, so the patient seeks solitude and silence.

An ocular migraine can be complicated by แทงบอล UFABET ราคาดีที่สุด ไม่มีขั้นต่ำ a headache localized in the frontal lobe and the bridge of the nose, passing to the eye sockets. It pulsates, intensifies, and weakens, as in labor pains, inevitably reaching a peak. At the peak of the attack, pain is complicated by nausea, vomiting, and a feeling of fullness in the head.

The average duration of an atrial fibrillation attack is from 30 to 300 minutes. A mild degree of anomaly occurs within 10-20 minutes and sometimes is not accompanied by headaches. After the end of the attack, it takes up to 1 hour to fully restore vision.

If atrial fibrillation is provoked by compression of 3 pairs of cranial nerves, the patient experiences:

• transient drooping of the upper eyelid
• dilation of the pupil in one eye while maintaining the size in the other
• dilation of the pupil against the background of paralysis of the muscles that regulate its diameter
• divergent strabismus due to paralysis of the oculomotor muscles in one eye.

Among the visual impairments in a retinal migraine of this form, there is a double image where one eye perceives the picture correctly, and the other transmits an image inverted horizontally or vertically. This picture is typical for children and adolescents entering puberty.

An ocular migraine with compression of the cranial nerves has a specific “Alice’s syndrome” consisting of the appearance of visual hallucinations visible with lateral vision.

Symptoms with ophthalmoplegic ciliated scotoma persist longer than with retinal scotoma – up to 2 weeks. All this time, anomalies can be accompanied by headaches but often proceed without them.

Causes of retinal migraine

The basis of retinal migraine is neurological dysfunction, leading to a disruption in the work of the visual analyzer. This condition develops due decrease in the tone of the posterior cerebral artery. As a result, transient retinal ischemia and oxygen starvation of the brain occurs. The disease neurological and is not associate with pathologies. That lead to changes in the tissues of the brain or eyes.

The appearance of ocular migraine attacks is associate with the effect of provoking factors on the body, the main. Which are consider by doctors the following

• chronic lack of sleep for an adult, a night’s sleep lasting 8 hours is necessary. Reducing it even by an hour, if this continues for a long time, leads to frequent attacks
• a sharp change in the weather
• rapid climate change. When conditions in a new place are seriously different from those that were previously
• severe stress
• emotional stress
