Ocular migraines can severely constrict and even frighten those affected. There are a variety of causes – if in doubt, seek specialist advice.
30 to 60 people in every 100,000 (a number which decreases significantly with age and around two-thirds of whom are women) suffer from a special type of migraine called an ocular migraine or retinal migraine.
The symptoms are temporary:
- Loss of field of vision
- Sensitivity to light
- Visual disturbances
- Nausea and dizziness
The symptoms often occur in both eyes at once, and unsettle or scare patients. They constrain sufferers in the workplace and sometimes even leave them incapable of working until the symptoms subside.
Research into the causes is based on shortcomings in our nervous system. Hormones play a role, as do external substances which can affect them such as alcohol, tobacco, or medication. Migraines often coincide with the menstrual cycle.
If they last for short periods of time then no treatment is required, but if they are longer-lasting, traditional and more modern migraine substances are used. This condition does not cause any damage or have any consequences.
However: It is extremely important that flickering vision is not confused with flashes in the vision, which often marks the beginnings of a detached retina – an ophthalmological emergency which can result in blindness if not treated.
If in doubt, consult your ophthalmologist immediately. Any reputable ophthalmic practice will be permanently prepared for this situation.
