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. ...Read more
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. ...Read more
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?

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
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. ...Read more

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?
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. ...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.
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?
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
? 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
Diabetes: Do discuss this with your physician.Get a more detailed answer ›
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
Light flashing: Medically called photopsias, these are the sensation of light streaking from retinal stimulation. This can occur if the eye is struck, and occurs spontaneously in middle to older age from fluid changes in the eye. If associated with floaters and loss of vision, you need to see your ophthalmologist to rule out detachment of the retina. ...Read more
Hard to say: This depends a lot on your age, and if you have any other medical problems or not. Sometimes eye conditions can cause flashes of light, and other times it can be part of a neurologic condition, like migraines, or vascular problem related to blood flow to the eyes. I would start by seeing my regular doctor or eye doctor and discuss this with them. ...Read more
Flashes in vision: See an eye doc soon! Could be simply a liquification of the jelly in the eye, which is normal, or something more serious like a retinal tear or hole. ...Read more
Retinal detachment: This could be due to detachment of the vitrous (jelly like substance in the eye) but it could also be an early warning of detachment of the retina. You should see your ophthamologist (eye doctor) to make sure. Retinal detachment can be treated and blindness prevented if caught early enough. ...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
