The Magical Mystery Of Migraines In ocular migraine, it is the retinal blood vessels inside the eye. The retina is the thin lining on the back, inner part of the eye that prepares images http://www.clevelandclinic.org/health/health-info/docs/3200/3266.asp?index=11253
Flashes And Floaters The retinal cells are incapable of perceiving pain, pressure, migraine flashes are usually caused by a spasm of blood vessels in the brain. http://www.agingeye.net/visionbasics/flashesandfloaters.php
Extractions: Floaters are entoptic images of opacities in the vitreous . Entoptic image is a visual perception that is produced by structures within the eye - in this case vitreous opacities. Patients complain of small specks or dots that can be seen against a bright background such as a diffusely illuminated wall or the blue sky. Sometimes fine dark lines in amorphous mass - like small branching twigs - are seen. These floaters move around and are also called 'muscae volitantes' because they seem to dart about like flies as the eye is moved. Over time you will become less aware of these floaters as the brain learns to ignore these retinal images. Therefore, while some floaters may remain in your vision, many of them will fade over time and become less bothersome. Floaters, if present since a long time or increasing in number very gradually, are harmless. They may be annoying but do not cause any problems. However if a new floater comes on abruptly or if there is a sudden increase in the number of floaters, then you must be examined immediately to rule out a retinal tear. Floaters may be due condensations of vitreous collagen (single or clumped hair-like floaters formed in degenerating/liquefying vitreous as occurs with aging) or due to blood (abrupt shower of small floaters usually from retinal tear), or glial tissue torn from an area adjacent to the optic nerve head (abrupt single or few large floaters, occurs in posterior vitreous detachment). A dilated fundus examination should be immediately performed for any abrupt increase in the number of floaters.

Preview : Acute posterior vitreous detachment (PVD) is the most common cause of unilateral floaters and flashing lights. These visual experiences are frightening to the patient, and they are usually accompanied by few, and often subtle, physical findings on eye examination. Patients with symptomatic PVD are at risk for retinal detachment and vision loss. In this article, the authors discuss the evaluation and management of unilateral floaters and flashing lights.

Extractions: DESCRIPTION: Paroxysmal headache lasting 4-72 hours. Episodes vary in frequency from more than once a week to less than one per year with symptoms abating completely between attacks. Premonitory symptoms consisting of non-specific symptoms occur frequently hours to days before headache. Most frequent sub-types are: Without aura - (common migraine) defining over 80% of attacks With aura - (classic migraine) characterized by focal disruption of neurological function begins and ends prior to headache onset Variants of migraine include: Transformed migraine - chronic headache pattern evolving from episodic migraine. Migraine-like attacks are superimposed on a daily or near-daily headache pattern, e.g., tension headache. Basilar migraine - occipital headache, with aura symptoms of dysarthria, vertigo, tinnitus, ataxia, and bilateral paresis or bilateral paresthesias Hemiplegic migraine - aura consisting of hemiplegia and/or hemiparesis Ophthalmoplegic - palsy of the ipsilateral third cranial nerve during the headache phase Retinal - symptoms of retinal vascular involvement during headache Childhood periodic syndromes - (migraine equivalents) recurrent often cyclic episodes of symptoms Status migrainous - persistent migraine which does not resolve spontaneously Migrainous stroke - persistent or permanent neurologic deficits persisting beyond migraine attack usually with neuro-imaging changes Chronic migraine - migraine-like headaches greater than 15 days a month for greater than 6 months

Extractions: Migraine Migraine may consist of severe headache, blurred vision and upset stomach. Vision disturbance such as flashing lights (kaleidoscope, zigzag, whirling, sprinkling stars) is often followed by vision loss which may be partial or total. It usually lasts 30 minutes. A headache may follow which is severe, piercing and often incapacitating. Finally, a queasy, upset stomach may follow. A person may have one part of the migraine syndrome only. Vision loss in migraine lasts longer than momentary vision loss or disturbance associated with poor circulation or retinal problems. Severe, persistent headaches should be reported to your family doctor. OUR EYE TOPICS Amblyopia
Floaters And Flashers Floaters could also signify retinal tears that might be threatening for vision loss. migraine flashers appear as zigzag, shimmering, or even colorful, http://www.mdsupport.org/library/floaters.html
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.

Extractions: The EyeCare Connection The phenomena of flashes and floaters are most often harmless but also may be a sign of important health problems. Floaters can be due to variations in refractive index (optical density) in the vitreous inside the eye resulting in shadows being cast on the retina. Imagine fiberglass strands submerged in water and illuminated by a flashlight. Although both the water an d the strands are clear they have different optical characteristics, and the strands will cast a shadow. All of these types of floaters are quite benign. They are harmless. It is common for floaters to appear suddenly and diminish in their appearance over time. The exceptions to these conditions are often signs of potential serious pathology. The serious floater: Occasionally floaters are warning signs of imminent danger or damage occurring somewhere in the eye. An internal hemorrhage of blood from a leaking vessel may cause floaters. They can also be caused by a Posterior Vitreous Detachmen t (PVD), a degenerative change in the vitreous allowing it to fall away from its normal position against the retina. This usually causes an acute increase in the number of floaters and is associated with increased risk of retinal complications. This is ra re in the under 50 crowd, with the incidence becoming more common by age 70 or so. The rapid onset of large and numerous floaters may signal an impending retinal detachment.
Glossary - Retina retinal diseases can also stimulate the retina and cause flashers. migraine flashers (scintillating scotomas) occurs in both eyes simultaneously, http://www.eyecaresite.com/glossary/retina_f.html
Extractions: Floaters can present as a few specs to hundreds of dark spots or objects "floating" in the field of vision. These may appear as strings, streaks, clouds, "bugs", dots, dust, or "spider webs". Floaters represent actual debris floating in the vitreous (gel that fills the eye). This debris may consist of blood, torn retinal tissue, inflammation ( uveitis ), vitreous detachment (see below) or a normal aging change in the vitreous. Floaters may also be the presenting symptom for sight threatening retinal tears or retinal detachments Since many serious eye diseases can present with floaters, it is important to see your Eye Care Center ophthalmologist within 24 hours of developing these significant symptoms. Flashers: Flashers can be perceived as "a sparkle or twinkle", "a disco light", "fire flies", "lightning", "fire works" or "sparks". They are generated by any abnormal stimulus to the retina (neural tissue lining the eye). Tugging by the vitreous (the gel that fills the eye) on the retina during eye movement or a vitreous detachment, can stimulate flashers If the vitreous tugs hard enough on the retina, a retinal tear can develop and a

Floaters And Flashes traction on the retina, vitreous detachment, migraines or retinal detachment. Sometimes flashes and floaters are the result 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
