Eyes And Seeing Black Spots

What are those floaty things in your eye Michael Mauser

Have you ever noticed something swimmingin your field of visioné It may look like a tiny wormor a transparent blob, and whenever you try to geta closer look, it disappears, only to reappearas soon as you shift your glance. But don't go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater. The scientific name for these objectsis Muscae volitantes,

Latin for quot;flying flies,quot; and true to their name,they can be somewhat annoying. But they're not actually bugsor any kind of external objects at all. Rather, they exist inside your eyeball. Floaters may seem to be alive,since they move and change shape, but they are not alive. Floaters are tiny objectsthat cast shadows on the retina, the lightsensitive tissueat the back of your eye.

They might be bits of tissue, red blood cells, or clumps of protein. And because they're suspendedwithin the vitreous humor, the gellike liquidthat fills the inside of your eye, floaters drift alongwith your eye movements, and seem to bounce a littlewhen your eye stops. Floaters may be onlybarely distinguishable most of the time.

They become more visiblethe closer they are to the retina, just as holding your hand closerto a table with an overhead light will result in a moresharply defined shadow. And floaters are particularly noticeable when you are lookingat a uniform bright surface, like a blank computer screen, snow, or a clear sky,

where the consistency of the backgroundmakes them easier to distinguish. The brighter the light is,the more your pupil contracts. This has an effect similarto replacing a large diffuse light fixture with a single overhead light bulb, which also makesthe shadow appear clearer. There is another visual phenomenonthat looks similar to floaters but is in fact unrelated. If you've seen tiny dots of lightdarting about

when looking at a bright blue sky, you've experienced what is knownas the blue field entoptic phenomenon. In some ways,this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windowsletting light through to your retina. The windows are actually causedby white blood cells moving through the capillariesalong your retina's surface. These leukocytes can be so largethat they nearly fill a capillary

As eyes age, the jelly inside the eyes calledthe “vitreous� breaks down and starts to float about inside of the eyes. These piecesof the vitreous can be small, or in some cases, very large and cobweblike. Floaters casta shadow against the retina at the back of the eyes and appear as flecks – they aremore visible against a white or uniform background such as the blue sky. In certain circumstances,the vitreous may remain partially attached to the retina and can tug on the retina whilein the process of separating. This tugging can cause a sensation of flashing lights andcan be an early indicator of a more serious condition called retinal detachment. In thecase of retinal detachment, the retina, which

acts like the film of the camera for youreyes, can be pulled right off. This is an eye care emergency and often quick diagnosisand early surgical intervention is required. Your of Optometry is trained to diagnoseand detect floaters and retinal detachments. It is important to have a dilated eye examinationwhenever new symptoms arise, such as a new large floater, flashes of light like indoorlightening, a sudden shower of floaters, or a black curtain over a portion of your vision.If you have these symptoms, call your of Optometry and book a sameday urgent examinationto rule out retinal detachment.
