Floaters disturbs my vision: What?
Floating liquids are translucent spots and rags that are in sight and vision. They are very common. They may have any shape and are hard to describe. Spells or fly or spider webs or frogs spawn are often used and can be so real that the person concerned can touch them. The imaginary medical name is "Muscae Volitantes", which means that I am the ones they can talk about. What is that?
The main inner cavity of the eye is filled with a gel-like material, the so-called vitreous body. It consists mostly of water chemically linked to fine molecular stands. This arrangement ensures the structure of the glass body. When we are kids, the glass body is usually like a set, but a shiny gel. As we age, its structure is gradually changing. The fine fibers tend to gather together and some of the water forms liquid pockets within the gel. The glass body will be a bit small. The fibers then move freely, like a fine mesh curtain, in a gentle breeze. Swimmers are more common in short-sighted eyes. This is because the glass body in this condition is much more fluid.
Moving fibers in the glass body can only be detected when passing near the field of vision to a bright uniform background. This can be white paper or light or evenly cloudy sky or something similarly illuminated. If the person looks at a complex mixed scene, the floats lose the details of the scene. What we actually see is the shadow that the floater cast on the retina. The retina is a vital "looking" layer that attracts the back line of the eye. Although float's actual dimension in the glass body can not change its appearance. This can be the case, for example, if the retinal distance is variable. If the float is just in front of the retina, it is relatively small but sharp shadows. If you move from the retina, it will cause a larger, fuzzy shadow; so it looks like the floating is bigger.
Over time, liquid pockets in the glass body are larger. This fluid can eventually penetrate the outer surface of the gel. This can happen suddenly, and "flashes and swimmers" may interfere with vision. The free liquid now surrounds the body of the glass body, which is tightened and becomes more mobile. As this creeps around the eye, the retina may creak. This transfers the electrical signal to the brain and the individual "sees" a momentary lightening like the phantom ray, usually the outside of the vision. These flashes are usually detected after dark. Nowadays it is not noticeable when other light floods them. Flashes disappear for several weeks as the gel becomes tighter and no longer wrinkles the retina. The floaters tend to survive, and can be a very distinct and largely circular float that accompanied the flashes. This is because it is as ringy as the fiber between the glasses and the optic nerve at the back of the eye, but now the hollow of the eye freely floats.
This is the process where the glass body is called "Posterior Vitreous Detachment (PVD)" for liquids and crashes. Before the PVD occurs, the outer surface of the vitreous body contacts the retina on the back of the eye. As the vitreous body separates from the retina and clamps inwardly, the retina must be disrupted. However, it may occasionally retract to the retina and break away. This can lead to retinal detachment. Therefore, the condition of the retina should be verified by an eye specialist if one discovers a sudden appearance of new swimmers.
In addition to normal fibers in the glass body, floaters may also have bleeding or inflammation in the eye.
