Blind Spot In Visual Field
Yes: Visual field testing will occasionally pickup small areas of visual field depressions if the floater is particularly large and thick, as some patients may have. Since they move, a repeat visual field should also show the depression to have moved. I would not however expect a large visual field abnormality from a floater and certainly l recommend an exam to rule out any problems by an eye md. ...Read moreSee 1 more doctor answer
??: Need a little more info about your question. I assume you're saying you have a blind spot centrally and your seeing scintillating light peripherally--typically lasting about 15 minutes, not usually associated with any other symptoms. Sounds like an acephalic migraine or ocular migrains, without headache, sometimes described as auras. Central blindspot is concerning though. See your eyemd. ...Read more
Migraine: You have described a typical pattern for occipital migraine, a condition affecting the circulation to the occipital lobe - the visual information processing part of the brain. These are benign, annoying but come from nothing and lead to nothing. Most are over in 5 minutes to 1 hour. If you get another, cover one eye, then the other and you will notice the sparkles in the same 1/2 of each eye. ...Read more
See an eye MD: It might be nothing or something as simple as a migraine. But it also could represent a blocked blood vessel that supplies the eye (almost like a mini stroke). You need to see an ophthalmologist who will determine whether any additional testing is required. ...Read moreSee 1 more doctor answer
Hemi-field loss: Is usually due to a pathology posterior (behind) to the eye itself. A lesion or area of pathology will usually be located from the area of the pituitary gland (approx. just forward of central brain) where the optic nerves cross to anywhere along the optic radiation ending at the occipital lobe (portion of the brain at the lower back of the skull). An MRI or CT can usually identify the cause. ...Read more
Potentially: Most likely a gray spot in your vision is a floater, however there are many other causes and some are vision threatening. The first step is to see an ophthalmologist and be certain of the diagnosis. If it is a floater, most of the time your ophthalmologist will not treat it as they usually become less bothersome over time. There is a procedure that a retina specialist can do to remove floaters. ...Read moreSee 1 more doctor answer
Is it possible to get accurate visual field test with macular pucker decline in visual acuity, lights less bright & white computer screen looking gray?
Usually it is fine: You have defects in the central visual portion of your field of view - an area poorly outlined by most field testing devices. Field tests will define major defects which largely will register from the peripheral areas tested. Have you had a field tested in the past? Is there some condition being sought for with a field.? Your ophthalmologist would not order a field if he doubts the result. ...Read more
Floaters big shadow in vision with vision acuity 6/6 both 12/12 eye pressure and pulsating in vision all drs saying there's nothing in retina??
In unilateral glaucoma with advanced visual field loss in that eye but perfect vision in unaffected eye is it safe to drive relying on good eye?
Generally yes: With 1 normally functioning eye & 1 that has severe visual field loss, your function is largely dependent on your ability to adapt to the missing field areas. As an American driver, visual field loss in the left hemifield & diffuse visually field loss in the right eye was associated with more driving impairment. Interestingly, a large % of monocular patients did well driving. Driving skills vary. ...Read more
BLIND SPOT: We all have a normal blind spot, the optic nerve head. There are other pathological blind spots occurring in diseased conditions such as glaucoma, solitary retinal hemorrhages, artery or vein occlusions etc. Stress alone is unlikely to cause such blind spots, but theoretically it could contribute to worsen a preexisting condition like hypertension, which may lead to retinal hemorrhages. ...Read more
Large dark floater in right eye & today developed floater in left eye. Retinas ok but floaters are distorting vision. Would cognitive therapy help?
Is this optical migraine? Flashing zig-zag @periphery of vision. Printed words distorted/stretched at periphery, like they're moving & fading in/out.
SEE EYE SPECIALIST: First, get visual field testing and map out scotoma, and compare with right eye. Could be retinal in origin, but certain patterns may correlate with optic nerve or brain lesions. Many causes, including glaucoma on occasion. An ophthalmologist is your best source of help. ...Read more
