What's the difference between photopsia and visual seizures? I had split-second flashes of light so i saw my eye md, but he found nothing wrong.

Photopsia is a flash: Of light that will nearly always occur unilaterally, or in one eye only. A migraine causes "scintillating scotomas". This is a scintillating absence of vision which typically does not lateralize - meaning it is not possible to say that it is in one eye or the other. A "visual seizure" or occipital lobe seizure mimics retinal migraine as both are due to occipital lobe dysfunction. ...Read more

Do symptoms like flashes of light go away quickly?

Do symptoms like flashes of light go away quickly?

Usually: Light flashes mostly are due to changes in the fluids in the back of the eye. The retina is jostled when this happens and responds with a light flash. You should see your ophthalmologist if this persists more than a day, if there are lots of floaters, if the vision drops, or if you see a grey -veiny veil in the vision. Do not delay as sometimes this can be a retinal detachment. ...Read more

Not always!: Posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". When it pulls away (initially tugs), it causes flashes. You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. ...Read more
