retinal migraine मीनिंग इन हिंदी

This is a different disease from retinal migraine, which is monocular ( only one eye ).
Ocular or retinal migraines happen in the eye, so only affect the vision in that eye, while visual migraines occur in the brain, so affect the vision in both eyes together.
Retinal migraine is a different disease than scintillating scotoma, which is a visual anomaly caused by spreading depression in the occipital cortex at the back of the brain, not in the eyes nor any component thereof.
The terms " retinal migraine " and " ocular migraine " are often confused with " visual migraine ", which is a far-more-common symptom of vision loss, resulting from the aura phase of the common migraine.
Unlike in retinal migraine, a scintillating scotoma involves repeated bouts of temporary diminished vision or blindness and affects vision from both eyes, upon which sufferers may see flashes of light, zigzagging patterns, blind spots, or shimmering spots or stars.
