Intermittent Peripheral Vision Loss
When you look at someone's face, you can still see their hand, even though you are not looking directly at it. When you are walking through a doorway, you are not looking at the sides, or looking directly at the threshold, but you see it through your peripheral vision. Anything outside of your direct focus spot, is considered peripheral. Which can be measured ...Read more
Auras, visual issues: Indicate the need to see an eye doctor or your family doc ASAP. The sooner this is treated the less likely it is to create permanent damage. Peace and good health. ...Read more
Occipital migraine: In this type of migraine, there is a loss of a portion up to all of the vision of 1/2 of the field of vision of both eyes (check by covering one eye and then the other). Usually the greyed out loss has a shimmering surround which flickers until it disappears. These type of migraines are benign, short lasting (usually less than an hour), and cause no permanent change. No worry unless frequent. ...Read more
Can optic nerve head drusen cause sudden unilateral loss of peripheral vision due to a spontaneous vascular event?
Recently diagnosed with glaucoma. No peripheral vision loss. 30% optic nerve damage. With treatment will nerve damage cause loss of vision?
Probably not: Glaucoma is readily treated with anti-pressure medication which should prevent any further damage in almost all cases. This is handled by ophthalmologists (you are not seeing an optometrist i hope?) who deal with this daily. There is a step ladder of treatments -- medication, laser, surgery to prevent further damage which can be quite effective. ...Read moreSee 2 more doctor answers
Seek help: Vision may be lost peripherally from disasters within the eye such as retinal detachment or vascular occlusion; or from strokes in the brain in the occipital lobe or the pituitary region; or from systemic vascular collapse, drug toxicity or poisoning. You need to immediately see an ophthalmologist for this as some of these are extremely urgent and can affect both eyes. ...Read more
Many possibilities: Many things can cause loss of peripheral (side) vision: glaucoma is the most likely. Ocular pressure rise causes vascular and optic nerve damage. Another is a tumor or aneurysm near the pituitary gland, compressing the nerves from the eye as they first join and then re-divide on the way to the back of the brain. Oculo-vascular occlusions can do the same although most often this is only in one eye. ...Read more
Can sudden peripheral vision loss due to optic nerve head drusen reverse, change in severity or fully recover?
Not typical!: Optic nerve he'd drusens are associated with field loss sometimes, but they are chronic and stable. I am not aware of them being associated with sudden loss. Look for a different cause! depending on the that, it may or may not be reversible (most likely not). ...Read more
Glaucoma with 30% optic nerve damage. No peripheral vision loss. For patient to notice peripheral vision loss, how much nerve damage must there be?
Variable: This depends upon the sensitivity of the nerves under the stress of the elevated pressure in the eye. Some will loss measurable amounts of vision at 30% damage, others require more loss to detect it. There is good adaptation so it takes a sensitive person to best detect loss. Best to get treatment and avoid any loss at all. ...Read moreSee 1 more doctor answer
Many things!: Changes in vision, blurriness, blind spots, halos around lights, or dimness of vision should always be evaluated by a medical professional. Such changes may represent an eye disease, aging, eye injury, or a condition like diabetes that affects many organs in your body. Other potential causes of vision problems include fatigue, overexposure to the outdoors and certain medications. ...Read moreSee 1 more doctor answer
Loss of vision reflects the inability to perceive images. Such a phenotype can be due to occlusive or barriers to light (e.g. cataracts) through retinal alterations (e.g. wet macular degeneration) to optic nerve lesions (e.g. from a pituitary adenoma) to central nervous system ...Read more
