Felicia,
I get ocular migraines. They aren't painful, just inconvenient. Didn't know what they were til we had a Calif. get-together and someone started talkng about them. I don't think they have anything to do with CH....just a really bizarre occurance. My brother has them too and he has never had CH. Neither one of us goes blind..just hard to focus or read due to the flashing lights. 20 mins later they're gone.
Here is the closest thing I found on-line.
Ocular Migraines (Ophthalmic or Eye Migraines)By Marilyn Haddrill; contributions and review by Charles Slonim, MD
Ophthalmic (eye) migraines are quite common and often painless, although the solo term "migraine" usually brings to mind a severe type of headache.
But with eye-related migraines, visual disturbances with or without headache pain also can accompany migraine processes thought to be related to changes in blood flow in the brain.
These visual problems associated with migraines technically are known as ophthalmic migraines, but are much more commonly (though incorrectly) called ocular migraines. Because most laypeople understand the term better, this article refers to the condition as "ocular migraine."
Migraines can be produced by the body's neurological responses to certain triggers such as hormonal changes, flashing lights or chemicals in foods or medications. One result of these triggers may be an intense headache that, if untreated, can last for hours or even days.
During migraine processes, changes also may take place in blood flow to the area of the brain responsible for vision (visual cortex or occipital lobe). Resulting ophthalmic or ocular migraines commonly can produce visual symptoms even without a headache.
Ocular Migraine Symptoms People with ocular migraines can have a variety of visual symptoms. Typically you will see a small, enlarging blind spot (scotoma) in your central vision with bright, flickering lights (scintillations) or a shimmering zig-zag line (metamorphopsia) inside the blind spot. The blind spot usually enlarges and may move across your field of vision. This entire migraine phenomenon may end in only a few minutes, but usually lasts as long as about 20-30 minutes.
Generally, ocular migraines are considered harmless. Usually they are painless, cause no permanent visual or brain damage and do not require treatment.
Still, always consult your eye doctor when you have unusual vision symptoms, because it's possible that you have another condition requiring treatment, such as a detached retina, which should be checked out immediately.
You've been around the block several times in your youing life with clusters. If a doctor is telling him something that that does NOT seem right, go with him and question, question question. Let that Doctor know that YOU know what you are talking about. Can Becky or your Dad go with him?????
