Photopsia. This is an approximation of the zig-zag visual of a scintillating scotoma as a migraine aura. It moves and vibrates, expanding and slowly fading away over the course of about 20 minutes. Migraine with aura, which includes photopsia 39% of the time, typically lasts 10 to 20 minutes and often is followed by a headache.
Duration depends on the cause of the vision loss. Obscured vision due to papilledema may last only seconds, while a severely atherosclerotic carotid artery may be associated with a duration of one to ten minutes. [6] Certainly, additional symptoms may be present with the amaurosis fugax, and those findings will depend on the cause of the ...
0.7 per million (1990) Recurrent painful ophthalmoplegic neuropathy ( RPON ), previously known as ophthalmoplegic migraine ( OM ), is a rare neurological disorder that is characterized by repeated headache attacks and reversible ipsilateral paresis of one or more ocular cranial nerves (CN). [1] Oculomotor nerve (CNIII) is by far the most common ...
Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy. The main symptom is loss of vision, with colors appearing subtly washed out ...
Empty sella syndrome. Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [ 2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain. [ 1]
Central serous chorioretinopathy ( CSC or CSCR ), also known as central serous retinopathy ( CSR ), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1][ 2] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
