Floaters are small specks or particles that float within the vitreous humor, which is the gel-like substance that fills the back portion of the eye. These floaters can appear as dots, circles, lines, or cobweb-like shapes that move or drift around as your eyes move. They are particularly noticeable when looking at a plain, bright background such as a clear sky or a white wall.
Floaters are typically caused by tiny bits of protein or other cell debris that clump together in the vitreous humor as we age. They cast shadows on the retina, which is the light-sensitive tissue at the back of the eye, and this is what causes us to see them.
The vitreous is capsulated and attached to the retina. As we age the vitreous humor turns less gel-like and liquefies which can cause the capsular walls to weaken. This occurrence can lead to a phenomenon called posterior vitreous detachment (PVD) which is a section of the capsule of the vitreous separating from the retina. During a PVD, you may experience symptoms such as an increase in floaters or flashes of light, especially in the peripheral vision. While a PVD itself is usually not a cause for concern and does not typically require treatment, it is important to have your eyes examined by an eye care professional, to rule out any complications. In some cases, a PVD can lead to a retinal tear or detachment, which may require prompt treatment to prevent vision loss.
While floaters are a common occurrence and are usually harmless, it is important to monitor any sudden increase in the number of floaters, especially if accompanied by flashes of light or a loss of peripheral vision. These symptoms could indicate a more serious condition such as a retinal tear or detachment, which requires immediate medical attention.
If you experience a sudden onset of floaters or any other changes in your vision, it is best to schedule an appointment with an eye care professional, such as an optometrist or ophthalmologist, for a comprehensive eye examination to rule out any underlying issues.
