An eye doctor is you: Eye doctor is your best source to answer this question. Unless you have headaches or any neurological symptoms, it is unlikely that your eye problem is due to a brain tumor. If the eye problem persists or gets worse you need to go see your doctor again and ask him this question. ...Read more

My eye doctor told me that papilledema (i don't have) often accompanies visual symptoms (vision loss, photopsia) caused by brain tumors. Why is this?

My eye doctor told me that papilledema (i don't have) often accompanies visual symptoms (vision loss, photopsia) caused by brain tumors. Why is this?

Eye = external CNS: The eye is the only externalized part of the central nervous system. Papilledema, swelling of the optic disc, is due to elevated intracranial pressure (icp) at the level of the lamina cribrosa, where the intraocular pressure (iop), if lower than the icp, permits swelling of the nerve fiber layer. Brain tumors or idiopathic intracranial hypertension (iih) can cause papilledema and visual loss. ...Read more

Why does anxiety cause me to see flashes of light?

See your doctor: Although anxiety can cause a variety of physical symptoms, flashing lights isn't a common one. It is important to make sure that there isn't a different problem causing the symptoms.

Check with your doctor, it could be more than anxiety. ...Read more

Flashes: Flashes are potentially a sign of a retinal tear or detachment and immediate evaluation is indicated. Other possible causes include intraocular inflammation and stimulation of the retina due to normal aging changes of the vitreous gel in the back of the eye. If you are currently seeing flashes, call an eye doctor immediately. ...Read more

See below: Floaters, flashing lights, or part of the peripheral vision missing (like a curtain or veil obscuring your vision) indicates the need for an urgent dilated retinal examination to rule out retinal tear or detachment. It could also be an ocular migraine, posterior vitreous detachment, retinitis, or tumor. Get it checked. ...Read more

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

Could you tell me what are leads to of flashes of light in vision with headaches?

Could you tell me what are leads to of flashes of light in vision with headaches?

? Migraine headache: This could be a headache migraine or an ocular migraine. The latter is usually not associated with pain, however. Migraine headaches can be associated with visual symptoms such as flashes, spots, formed hallucinations, etc. I'd recommend a systemic physical exam to rule out medical problems. If physically normal then have ophthalmologic evaluation to rule out ocular problems. ...Read more
