Extractions: Filtering Out Short Wave Light Eliminates the Onset of Migraines In the July '99 issue of Migraine Action News, a monthly UK newsletter for migraine sufferers, we asked for those willing to take part in a study looking into whether specialist spectacle filters can help prevent or reduce the symptoms of migraine, to contact us. It was by chance that a Migraineur who subscribes to Migraine Action News had received information on behalf of her daughter who suffers from RP. She contacted me to inquire whether we could do anything to help her with her own migraines. Experimenting, we found that indeed, by filtering out short wave light we completely eliminated the onset of migraines and so enabled her to return to her work in Court and as she terms it 'returned her life to normality'. At the same time, a piece of scientific research carried out at Kings College Hospital, London was being concluded which supported our own experiences by identifying the light at the extreme ends of the spectrum as being a common trigger amongst migraine sufferers. They also found that the light sensitivity before, during and after the migraine is attributable to those same frequencies. Like Retinal Disorders, many sufferers are aware of a link with light sensitivity, whether as a contributing cause or symptom associated with the problem. Many sufferers can be quite specific about their particular sensitivity in various situations, for example, under certain lighting, at a computer, car headlights, watching TV etc.

Visual Flashes, Floaters, and Migraine Auras Most of us occasionally note small gray or black blurred strings , cobwebs , or dust specks drifting across our vision .These are vitreous floaters ; although annoying , occasional floaters are generally of little significance. The vitreous jelly is the transparent , sticky , jelly-like substance that takes up much of the volume of the eyeball . It is more than 99 % water , but is kept in a gel state because of the presence of hyaluronic acid and collagen fibrils .The vitreous acts as a structural cushion which maintains the shape of the eyeball , but which is also optically clear , allowing light to pass through the inside of the eye to the retina . As we age, the gel partially liquefies , and the vitreous collagen fibrils form condensed aggregates which cast shadows on the retina . These floaters move around in the liquid vitreous with natural eyeball movement. While collagen fibrils give rise to whip-like floaters , small speck-like floaters represent individual red blood cells or epithelial cell debris in the vitreous . With further liquefaction and shrinkage of the vitreous , increasing numbers of floaters may suddenly develop . The collapse of the vitreous is a natural aging process called a '

All possible diagnoses and treatment options are not covered, and the information discussed should not be taken as a recommendation to self-diagnose and self-treat a condition. A misdiagnosed or improperly treated eye condition can result in a permanent loss of vision, or a permanent loss of function of the eye or visual system. In the case of any eye problem, seek medical attention promptly. This can include emergency room treatment, as well as treatment by a medical physician or eyecare provider. This page discusses unusual visual phenomenon such as floaters and different types of flashing lights. Other visual abnormalities such as seeing rainbows around lights, abnormal color vision, and distorted vision are discussed as well.

Conditions: For eye anatomy explanations, go to ANATOMY Floaters and Flashing Lights These symptoms usually resolve over a period of days to weeks, although some people will continue to see the floaters for a longer period of time. The important thing is to determine that the retina is healthy as the vitreous detaches. This requires a careful dilated examination of the retina to look for tears, or other areas which may be at risk for tearing. A retinal tear can then lead to retinal detachment, if not treated. Thus, people experiencing these symptoms should be examined by an ophthalmologist as soon as possible. (Note, only about 1 in 10,000 cases of vitreous detachment lead to retinal detachment, but it still is one of the most common causes of retinal detachment.)

Extractions: One printed copy is permitted for personal use only. by Judy Prevost Floaters are actually cellular debris within the vitreous, the jelly-like fluid that fills the inside of the eye. They may be seen as strings, streaks, clouds, bugs, dots, dust, or spider webs. These objects appear to be in front of the eye, but they are really floating in this fluid, and at the same time, casting their shadows on the retina, the light sensing inner layer of the eye. The debris could be made up of blood, torn retinal tissue, inflammation, vitreous detachment, or could simply mean a normal aging change in the vitreous. Floaters could also signify retinal tears that might be threatening for vision loss. The vitreous fluid degenerates during the middle age years, often forming minute debris within the eye. Floaters are also often noticed in people who are nearsighted (myopic), and those who have been operated on for cataract or Yag laser surgery. Floaters could interfere with reading, and can be quite bothersome. Even though there is no treatment or cure, they may slowly fade out over time. One possible remedy is to move the eyes up and down when a floater appears. The vitreous fluid may shift, thus permitting the floater to move out of the line of vision.
Floaters And Flashes Flashes. Flashes are the result of four possible events traction onthe retina, vitreous detachment, migraines or retinal detachment. http://www.oregoneyecenter.com/flashes.htm
Extractions: VISION CORRECTION ... LINKS AND CREDITS Inside the eye, in the middle of it, is a jelly-like substance called the vitreous . This jelly is loosely attached to the retina , the delicate sensory/nervous tissue of the eye. The function of the vitreous is to keep the eye taut and round, much like the foam inside pillows and stuffed animals. When we age, the vitreous dehydrates and gets smaller. When this happens the hyaline and collagen which make up the vitreous clump together. When light shines into the eye, these clumps make shadows on the retina. This is what we see as floaters. Sometimes they look like a spider, bug, worm or cloud. They can best be seen when looking at blue or white sky, and are often noticed while looking out the window of an airplane. Removing these clumps is considered too risky because vitreous is attached to the retina and floaters are left alone. They usually drop down out of the pupil with time as a natural result of gravity. Flashes are the result of four possible events: traction on the retina, vitreous detachment, migraines or

Extractions: Small Specks and Flashes of Light in the Field of vision. s ometimes people see small spots or specks moving their field o vision or experience flashes of light. These occurrences are called floaters and flashes. Although annoying, floaters and flashes are generally a little importance. However, in some cases, floaters and flashes may be the symptoms of a more serious eye problem, such as retinal detachment. What is a Floater? A floater is a small clump of gel that forms in the vitreous, the clear jelly-like fluid which fills the cavity inside the eye. Floaters may be seen as dots, lines, cobwebs or spiders and are most often noticed when reading, looking at a blank wall or gazing at a clear sky. Although floaters appear to be in front of the eye, they are actually floating in the fluid inside the eye. Sometimes, floaters do not interfere with vision at all. However, when a floater enters the line of vision, light is blocked and a shadow is cast on the retina. (The retina is the thing lining at the back of the eye that converts images to electrical impulses which are then sent by the optic nerve to the brain.) What causes floaters?

La funduscopia derecha mostró un exudado algodonoso en la mácula, secundario a microinfarto en la capa de fibras nerviosas. La campimetría reveló un escotoma superponible a la lesión retiniana. Discusión: Se trata de un caso extremadamente infrecuente de pérdida visual permanente en el contexto de una migraña. Realizamos una revisión de los mecanismos etiopatogénicos actualmente admitidos y los relacionamos con el caso presentado. Palabras clave: Migraña, retinopatía, infarto retiniano. SUMMARY Case report: We report the case of a 17-year-old man with migraine and prophylactic treatment with flunarizine who suffered loss of vision with black spot in right eye 36 hours after stopping treatment. The right fundus showed a macular cotton wool spot due to microinfarct in the nerve fiber layer. There was a scotoma in the visual field in the same localization.
