Can someone see flashes of light caused by moving positions too fast? Would this be a concern if they DON'T happen often? Floaters too.

Can someone see flashes of light caused by moving positions too fast? Would this be a concern if they DON'T happen often? Floaters too.

Yes: Sounds like you may have had a temporary decrease in blood flow to your optic nerve and retina from abrupt alterations in your positioning. I would be worried only if this happens when your not moving around abruptly. I would see a doctor for a depressed exam for the floaters to make sure you don't have a tear. ...Read more

Intra ocular hypertension 23hgmm visual field still clear. Glaucoma meds 13 till 16yrs with only slight decrease in iop off meds since. Rare photopsia?

Ocular hypertension: The term ocular hypertension (oht) implies that the eye pressure is high without optic nerve damage or visual field loss. In many cases oht can be followed on no meds as long as periodic optic nerve testing is done (visual field, oct, photos). The corneal thickness has been found in influence the pressure measurement, and in cases of very thin corneas, treatment might still be recommended. ...Read more

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.

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

Went to eye doctor because I thought I may have seen a flashing light in my peripheal for a split second. He found nothing wrong. Is photopsia hard to miss when you experience them?

Went to eye doctor because I thought I may have seen a flashing light in my peripheal for a split second. He found nothing wrong. Is photopsia hard to miss when you experience them?

Yes. Often.: Clinicians cannot see your flashes. Only you can see those. We can however, explain flashes on the basis of subtle changes in the vitreous gel and signs of traction on the retina. Most unilateral flashes are a result of vitreous traction - also not always evident on exam. So, if exam is normal and no (retinal) defects were found, I wouldn't worry. Inform your doctor if you have any rd signs. ...Read more

If physically normal then have ophthalmologic evaluation to rule out ocular problems. ...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

Difference between phosphenes and flashes of light (vision). How to distinguish them qualitatively and quantitatively?

Similar: A phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye. Flashes of light in the vision if flashing light are not actually present would be the same thing. This is usually caused by tugging of the vitreous (jelly of the eye) on the retina or ocular migraines, where the occiptal lobe perceives flashes of light generating in the brain. ...Read more
