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

Many eye s and patientsunderestimate the difficulty involved in instilling an eyedrop. The most important errors that we observedwere touching the tip of the bottle to the skin or theeyeball itself. This can result in contamination andpossible infection. We also observed individuals who miss theeye entirely with the eye drop and others whosqueeze the bottle forcefully enough so that manyeye
drops instead of one are instilled in theeye. One should always wash one's hands beforeplacing an eye drop Assume a comfortable position, either onthe sofa or on the bed. The point is to get the face pointedtowards the ceiling. Grab the bottle with your dominant handbetween your thumb and your forefinger. After removing the cap from the bottle,grab a tissue with your other hand. Pull down on your lower lid. This creates a pocket or target for you toaim for with the eyedrop.
With some bottles the drop, when thebottle is inverted, will spontaneously leave the tip, and will hitthe surface of your eye. With other types of bottles, you will needto apply gentle pressure, blot any extra fluid that youfeel on your cheek. If you're using eye drops in both eyes,repeat in the other eye. Remember, just because you Feel fluid onyour cheek does not mean that you did not get the drop in youreye. Glaucoma eye drops are medication and theydo have the potential to
travel from the eye into the back of themouth and nose. From there they can enter the bloodstreamand potentially cause side effects that affectthe whole body. Although there's only a small percentageof patients where this will occur, you should ask youreye whether he should perform eyelidclosure to reduce the amount of medication that gets intoyour body.
