I have flashing/flickering lights in my head.  Had opthomologist check retina in May and the retina was good.  Flickering continues (has been for nearly a year).   The past month I have been recording the frequency of this condition.   It occurs both in the morning and evening, ranging from 10-15 times a day, more frequently in the evening than in the morning.  There is no headache or pain involved.  I am 78 years old and did suffer severe migraines  20-50 years of age.  What could be causing this?
Hi there, thanks for asking. That could be related to the vitreous part in the eye. It also could be related to cataract in the eye which causes refractory issues. It could also be related to migraine that you have its history. You should explain a little more about your situation to your doctor to see what it could be. You can also put a question for me in this site to see.
