Retinal migraine
Symptoms of retinal migraine
The symptoms of retinal migraine may include:
- partial or total loss of vision in one eye this usually lasts 10 to 20 minutes before vision gradually returns
- headache this may happen before, during or after the vision attack
It's unusual for an episode of vision loss to last longer than an hour. The same eye is affected every time in almost all cases.
Vision may slowly become blurred or dimmed, or there may be flashes of light. Some people see a mosaic-like pattern of blank spots (scotomas), which enlarge to cause total loss of vision.
