Thank you for the question.I am Dr.A.S.Desai and I look forward to assisting you .
Your symptoms are suggestive of fortification spectrum seen in acephalgic migraine. This can occur at any age and may or may mot be recurrent. Headache might be mild or absent. The spectrum is said to occur due to altered blood flow in the blood vessels in the brain. However it does not lead to any problems or complications. Each episode can last anywhere between few minutes to an hour. It does not leave any permanent visual defects. It does not have any specific treatment . However recurrent episodes can be treated with migraine prophylaxis , which can be prescribed by your physician.

I hope the fortification spectrum or scintillating scotoma of migraine has now reduced. Please let me know if you had anything else to ask in this regard.If you continue to have a headache then you can take Tablet Tylenol, 500 mg 1 tablet right now and repeat after 12 hours if headache recurs. Thank you.
