Eye Floaters Causes
There are many conditions that can cause eye floaters. We will go over the most common in this article.
As one gets older, the vitreous humor (see diagram) gradually changes. Some persons have a more liquid vitreous that is more likely to cause floaters, while others retain a firmer vitreous throughout their lives. Even with minimal vitreous movements, small pecks of the vitreous itself become detached; floating around the vitreous and casting a shadow into the retina. This shadow can vary in size and shape, and it's what we know as eye floaters.
Although Vitreous Syneresis is generally the result of normal age-related causes, certain eye conditions can lead to it as well. Any eye condition that can physically alter the shape of the eye, even if just the vitreous, can lead to floaters. A few examples are: eye infections, eye inflammation, facial alteration (plastic surgery, wounds) and vitreous detachment. This is why it's not uncommon for very young people to develop eye floaters.
Posterior Vitreous Detachment
As a person ages, the gelatinous structure of the vitreous may start to shrink. As a result, many particles detached from the edges of the vitreous may move to the center of the eye, causing floaters.
Additionally, the vitreous is attached to the optic nerve. As the vitreous shrinks, this attachment starts to break; leading to enormous floaters that were the actual attachment between the vitreous and optic nerve. According to research, about 50% of people aged 65 and older will have Posterior Vitreous Detachment in one or both eyes. Developing PVD in one eye almost invariantly leads to PVD in the other within 18 months. PVD is especially common in persons who have undergone floaters surgical treatment, as up to 50% of them develop PVD within a year.
Many drugs in the market have several side effects. Some of the chemicals contained in such drugs are known for altering the chemical balance in the body often causing unknown side effects. Drugs to watch out for include skin treatment drugs, weight loss pills, mental recovery medicine and certain illegal drugs.
It's important that you try to keep your body as drug-free as possible. Many persons have reported the sudden appearance of eye floaters after ingesting certain medications.
Not only eye surgery, but many other facial surgeries can lead to eye floaters. As the face swells, pressure is exerted on the eyes. This is often enough for small particles to detach from the vitreous or retina causing new eye floaters.
The riskier surgeries are those associated with the eyes, for example LASIK or cataracts surgery.
Age related changes
Floaters tend to become more prolific with age, because the vitreous humour degenerates with advancing years and pulls slightly away from the retina. This separation of vitreous humour from the retina can cause small shreds of jelly to break off and form more floaters. At first, this can be irritating. Over time, the brain can become accustomed to the floaters and may decide not to 'inform' you of their presence.
Head and Eye Trauma
Blows to the head or eyes can be devastating. Although the vitreous is firmly attached to the retina, a strong blow may cause particles to detach from the vitreous leading to new eye floaters. In certain professions such as boxing, the occurrence of retinal detachment is very high.
Eye scratching and touching may also create new eye floaters.
There are many other eye floater causes. In general, any substance floating in the vitreous that is not entirely transparent will lead to eye floaters. This can include: red blood cells, white blood cells, darker vitreous spots and even tiny remains of an eye surgery.
Now that you know the probable causes of eye floaters, you should keep informing yourself in order to make an accurate decision. If you haven't already, consult a doctor as you may have retinal detachment that is a very serious complication that can make you blind.
