Floaters are caused by changes in the vitreous gel, a substance that fills the area at the back of our eyes. As we age, the vitreous and its collagen fibres degenerate, and the gel becomes stringy and opacified.
Floaters cast shadows on the retina and become perceptible under specific lighting conditions. When you move your eyes, they float around and dart away when you try to look at them directly.
There is no specific treatment for floaters. Sometimes your brain will learn to ignore them and as a result, your vision will begin to adapt and you may not notice them as much.
If it becomes too distracting or if it begins to impair your vision, have your eyes checked with an eye specialist – it is important to rule out retinal tears or detachment as the cause (read here for retinal disease treatment). The following is the treatment that is usually prescribed when floaters hinder your vision:
This treatment involves aiming lasers at the floaters which causes them to disintegrate. The procedure is painless and is performed after anaesthetic eyedrops are applied. To obtain the desired outcome, more than one laser session may be required.
