Eye floaters are a common visual phenomenon experienced by many people, often described as small, shadowy shapes that drift across your field of vision. These shapes can manifest as spots, threads, or cobweb-like structures. They move when you try to look at them directly. While floaters are usually harmless, understanding what they are and who is more likely to get them can help you manage them better.
What Are Eye Floaters?
Eye floaters are tiny clumps of gel or cells inside the vitreous gel-like substance that fills the inside of your eye. As we age, the vitreous slowly shrinks and becomes more liquid, causing microscopic fibers within it to clump together and cast shadows on the retina. These shadows are what we perceive as floaters.
Floaters can take on various shapes and sizes, including:
- Black or gray dots
- Squiggly lines
- Thread-like strands, which can be knobby and semi-transparent
- Cobwebs
- Rings
Who Gets Eye Floaters?
Aging Population: The most common reason for floaters is aging. People over the age of 50 are more likely to experience floaters because the vitreous humor undergoes natural changes as we age. By age 80, many people will have experienced floaters at some point.
Nearsighted Individuals: People with myopia, or nearsightedness, are more prone to developing floaters at a younger age. Because of the elongated shape of the myopic eye, this increases the likelihood of changes in the vitreous humor.
Eye Trauma and Surgery: Individuals who have experienced eye trauma or undergone eye surgery, such as cataract removal, are at higher risk for developing floaters. These procedures can cause changes in the vitreous humor, leading to floaters.
Inflammatory Conditions: Conditions that cause inflammation inside the eye, like uveitis, can cause floaters. Inflammation can lead to the clumping of cells and debris in the vitreous, creating floaters.
Diabetic Retinopathy: Studies show that people with diabetes face a risk of developing diabetic retinopathy, a condition that damages the blood vessels in the retina. This damage can lead to blood or other fluids being released into the vitreous, resulting in floaters.
Posterior Vitreous Detachment (PVD): PVD is a common condition where the vitreous gel separates from the retina. This detachment can cause a sudden increase in floaters. While PVD itself is usually not sight-threatening, it can occasionally lead to retinal tears or detachment, these require immediate medical attention.
When to See an Eye Doctor About Floaters
While most floaters are benign and not more than a nuisance, a sudden increase in floaters, especially when accompanied by light flashes or loss of peripheral vision, could indicate a serious condition such as a retinal tear or detachment. If you experience these symptoms, seeking immediate medical attention is crucial.
