Thanks for providing more information.
I understand your concern.
You are correct that ocular migraines have typical zig-zag pattern lights. They typically last 15-20 minutes however. They have a typical pattern of enlargement and then fade away.
Ocular migraines are diagnosed when there are no other identifiable causes.
If you notice a sudden increase in floaters, flashes of light (like a lightening storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment and consult your Eye specialist.
Also some triggering factors can be associated with the ocular headache like Caffeine
Hormonal imbalance, Insufficient sleep,Stress and anxiety,Strong smell,foods like chocolate, cheese and food enhancer like mono-sodium glutamate (MGM).
A massage or heat applied to the back of the upper neck can be effective .
Try OTC Migraine Ice, TheraPatch Headache Cool Gel that cools the skin for up to 4 hours and can be placed on the forehead, temple, or back of the neck.
You may need MRI or CT scan of head to rule out other causes of headache if your symptoms 'll not relieved
I advice you to see neurologist for the physical examination for further management.
Hope this helps.
