Causes Of Photopsia
I went to eye doctor because I had photopsia. He found nothing wrong but I worry about having a brain tumor. What does photopsia caused by brain tumor look like?
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.See 1 more doctor answer
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.See 5 more doctor answers
Migraines: Migraine disorders often exhibit severe head pain accompanied by visual symptoms including sensitivity to light and flashes of lights.
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. High blood pressure, even if worsened by anxiety, needs to be addressed medically and can cause that kind of symptom. Migraines and seizures can do the same. Check with your doctor, it could be more than anxiety.
How come I see purple flashes of light in my vision at night when I'm driving? It happens sometimes during the day also. Any idea what causes that?
Get checked: You need to make sure it is not a retinal tear developing.
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.
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.See 1 more doctor answer
What causes flashes of light in your eyes and once in a while dizziness. This has been occurring to my husband for a week or more, should he be concerned (he is working out of town)
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.
I was looking in the mirror at my tonsils and now in seeing nothing but flashes of light like lines is it from the light or my jaw Cause it started right after I closed my mouth Could my jaw have brok?
No: No if you broke your jaw you will know it my advice go and see your PCP or ENT you will be well examined, you will be either assured or treated
Sudden flashes of light & increase eye floaters. Saw 2 eye doctors who confirmed I had a normal retina with no tear or detachment. What can cause it?
Retina specialist: Go see retina specialist. It definitely sounds like you have a retinal tear somewhere.
Eye exam: Photopsia is a general term. It may be due to migraines is if it lasts for minutes. It is of retinal origin if it lasts for seconds. You need to see an ophthalmologist to determine the cause. Flashes and floater can be a sign of a retinal tear which can lead to a retinal detachment.
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.See 1 more doctor answer
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.See 1 more doctor answer
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.See 3 more doctor answers
? 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.
