Talk:Retinal migraine

Ocular migaine

The supercategory is not covered on WP. Rich Farmbrough, 19:20, 12 February 2011 (UTC).

The references treat ocular migraine the same as retinal migraine. The supercategory is amblyopia which is any disturbance of vision. The important distinction is between retinal disease in one eye and disturbance of visual processing in the brain which affects vision in both eyes. Greensburger (talk) 02:53, 13 February 2011 (UTC)

Contradictory loop

Ok, there's a bit of an internal inconsistency here. This article states that retinal/occular migraine is *not* the same thing as scintillating scotoma, which is a particular aura symptom of migraine in general. The Scintillating scotoma page describes how the scotoma may be the only symptom of migraine, in which case the event is a kind of silent migraine. But the silent migraine page says that if the only symptom is the scotoma (as opposed other auras), then the event is a retinal migraine.

The article currently makes it very clear that,

"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, such as the retinas.[3] Such a scintillating aura affects both eyes, and sufferers may see flashes of light; zigzagging patterns; blind spots; and shimmering spots or stars. In contrast, retinal migraine involves repeated bouts of temporary diminished vision or blindness in one eye."

Scintillating scotoma affects both eyes, indeed it persists against the eyelids with eyes closed, and is not a retinal event at all. Perhaps we should distinguish retinal from occular migraine, with scotoma a necessary symptom of the latter?--Dr satsuma (talk) 18:01, 12 April 2011 (UTC)

Confusion about terms

This page is not consistant with comments from the Mayo Clinic ([1]). They state that Ocular Migraine refers to two different conditions. It can refer to a generally harmless migraine aura (flashes, zigzagging patterns, etc), or it can refer to "reginal migraine" which is rare, effects vision in only one eye, and can lead to retinal damage.

Stanford Hospital ([2]) refers to the more harmless migraine aura as an "Ophthalmic Migraine", says they are not dangerous and usually appear in people in their 50s or older. That in contradiction to one of the related wiki pages that states late-onset is unusual and dangerous. 98.225.61.103 (talk) 22:37, 5 January 2013 (UTC)
