Migraines are thought to be caused by the dilation and constriction of arteries in the head. These can be extremely painful headaches. The pain is often limited to one side of the head, and may be accompanied by nausea and vomiting.

Most often, visual migraine, just like regular migraine headaches, can be brought about by stress, fatigue and changing estrogen levels. It occurs more often in females and more often during adolescence and menopause. On rare occasions these visual attacks are associated with other more serious problems.

Age Related Macular Degeneration

Age-related Macular Degeneration or AMD is a common eye disease that causes progressive damage to the central part of the retina, also known as the Macula. AMD is the leading cause of visual impairment in the United States, and blindness in senior citizens of America, aged 65 and older.

As people age, the retinal pigment epithelium (RPE), which supplies nutrients from the choroid (layer of blood vessels that nourishes the cones and rods of the retina) to the retina and helps remove waste products, may deteriorate. This results in the formation of waste deposits and the light-sensitive cells of the macula may be damaged due to lack of nutrients. The normal signals sent through the optic nerve to the brain by these cells become disrupted and the vision becomes blurred.

Is There Anything I Can Do To Prevent Macular Degeneration?

Unfortunately, there are not any known ways to completely prevent age related macular degeneration. That said, there are many ways that you lower your risk. These tips have been known to help those who were genetically pre-disposed to macular degeneration. Below are some secrets in lowering your risks before it is too late.

Get your eyes examined early. Regular eye exams are critical in determining if you are at risk for developing macular degeneration or not. If you are pre-disposed genetically, you should make sure to schedule annual exams. This will help prevent potential eye loss later. It could also delay loss of vision of the doctors can detect it early on.

Quit smoking. It is a known fact that those who smoke are up to 2 times more likely to have macular degeneration. The earlier you quit the lower the risk. Eat well. By modifying your diet to eat more nuts and fruit can help you lower your odds of getting macular degeneration. If you are allergic to nuts, you can take vitamins or supplements that are rich in omega-3’s as well as vitamin A and luteins. If you are already suffering from dry macular degeneration, there are measure you can take to prevent it from advancing. Some of these are:

Eat your spinach. By modifying your diet to eat more dark green vegetables you can actually slow the progression and further vision loss. Your doctor may also want you to take vitamins and supplements.

Exercise. By maintaining a healthy weight you will also lower your risk in getting more advanced forms of AMD.

Ocular Migraines
Normally when someone says the word "migraine" you think of a really bad headache. There is another type of migraine though, an ocular migraine. They are also called ophthalmic migraines. This is when visual disturbances occur with or without headache pain.
Ophthalmic migraines often occur when changes take place in blood flow to the area of the brain responsible for vision (visual cortex or occipital lobe). Hormonal changes seem to be a frequent trigger of these types of migraines.

Link Between Tinnitus and Visual Snow

The majority of those who suffer from visual snow, also have tinnitus.

Tinnitus is a ringing, whooshing, persistant noise that seems to come from the ear or head. Nearly 36 million Americans suffer from this disorder. Tinnitus is much more common than visual snow, but the two seem to be closely linked. Tinnitus is hearing what others can not, while visual snow is seeing what others can not.

Tinnitus can come from any of the four sections of the ear: the outer ear, the middle ear, the inner ear, and the brain. While some tinnitus is normal it should not disrupt you or be apparant in situations where there is noise. When you can hear it all the time, you level of tinnitus is elevated.

A common cause of tinnitus is damage to the microscopic endings of the hearing nerve in the inner ear.

Currently, like visual snow, there is no treatment for tinnitus. Research is being conducted to try and find a cure.
