Causes of eye floaters
Nearly everyone experiences eye floaters as they are very common. They are basically particles floating in front of the eye, and cannot be got rid of by merely rubbing as they are within the eyeball. They follow the movements of the eyes while drifting slowly from one place another. It is this movement that makes the floaters visible, otherwise due to neural adaptation they would be practically invisible. These floaters can be unsafe and hazardous and can be damaging to one’s quality of life.
The danger of floaters
They can be dangerous in the sense that they might mess about with and disturb normal everyday activities such as driving or using the computer. Usually eye floaters are not indicative of any eye disease since at some time or the other everyone one experiences these without any apparent negative effects. However, if all of a sudden they increase in quantity, and are seen in every background then it is advised to immediately seek medical advice, because they could be indicative of retinal detachment.
If somehow the retina has been separated or has a hole in it, then the person begins to experience eye floaters in greater numbers and will also feel that lights are flashing before his/her eyes. These two basic symptoms might be followed by loss of sight, so it is imperative to seek medical advice immediately, because surgery is usually needed to close up any hole in the retina or re-attach the retina to the back of the eyeball.
What causes eye floaters?
Basically light entering your eyes causes your retina to respond to produce an electrical signal which is communicated to the brain. The brain then translates this signal or light into the image that the eye is seeing. An uncommonly big floater is like a spherical form of thick, reduced gel that is similar to glass which is tightly entwined around the optic nerve. When this glass like substance is detached from the optic nerve, it forms a round shaped floater in the person’s vision. This ring then doubles upon itself, which creates a J or C form of floater.
Other Conditions Associated With Eye Floaters and Flashes
Bleeding is usually noticed which means extra-ordinary friction has occurred, which heightens the probability of a retinal tear or separation. Friction exerted on the retina during a Peripheral Vascular Disease can also cause yellow spots near the retina. When a person is nearsighted, then his/her stretched out shape also increases the possibility of Peripheral Vascular Disease. Many people develop PVD at a very young age.
PVDs usually occur after a person has undergone cataract surgery or a procedure which is called a YAG which is a a surgical procedure involving cutting into the capsule surrounding a body part, e.g. cutting into the lens of the eye during the removal of a cataract. The laser is basically for the treatment in which residue develops in the capsule underneath the artificial lens. These eye procedure increase shock and disturbance inside the eye, which then leads to vitreous detachments.
