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 moreSee 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. ...Read moreSee 2 more doctor answers
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

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 moreSee 1 more doctor answer
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
