Floaters: Why Young People with Mild Myopia Experience Them - Ophthalmology

Floaters, with mild myopia?


Hello Doctor: Recently, over the past month or two, I suddenly noticed a fairly large floaters in my right eye.
I recently underwent a retinal examination and everything was normal, but during the day when I look at the sky, I also notice that both of my eyes have many small, more transparent floaters.
I would like to ask why, despite my relatively mild myopia (right eye -2.25, left eye -2.75), I am experiencing floaters at such a young age? The thought of having floaters for a lifetime is quite discouraging, especially since the large floater is really hard to ignore!

Hello, floaters can occur at any age from 0 to 100 and are not necessarily related to the degree of myopia.
If there are no pathological changes, it is recommended to coexist peacefully with them.

More Info


Floaters, or "muscae volitantes," are small specks or strands that drift through your field of vision. They are particularly noticeable when looking at a bright background, such as a clear sky or a white wall. While floaters can be concerning, especially for younger individuals, they are often a benign condition.
In your case, experiencing floaters at a relatively young age, especially with mild myopia (nearsightedness), is not uncommon. Myopia can lead to changes in the vitreous gel, the clear gel that fills the space between the lens and the retina in your eye. As people age, the vitreous gel can begin to shrink and pull away from the retina, which can create the appearance of floaters. However, this process can also occur in younger individuals, particularly those with myopia.
The reason for this is that myopic eyes tend to have a longer axial length, which can lead to a higher likelihood of vitreous changes. These changes can include the formation of floaters as the gel becomes more liquid and less cohesive. The floaters you see are actually tiny clumps of collagen fibers within the vitreous that cast shadows on the retina, which is why they appear as spots or strands in your vision.

It's understandable to feel anxious or frustrated about the presence of floaters, especially if they are large and noticeable. Many people report that floaters become less bothersome over time as they learn to ignore them. However, if you notice a sudden increase in floaters, flashes of light, or a shadow in your peripheral vision, it is crucial to seek immediate medical attention, as these could be signs of a retinal tear or detachment.

In your case, since you've already had a thorough examination of your retina and no issues were found, it's likely that your floaters are benign. It's important to maintain regular eye check-ups, especially as you notice changes in your vision.
Additionally, while floaters can be persistent, they do not typically indicate a serious underlying condition. Many people live with floaters without any significant impact on their daily lives. If the floaters are particularly bothersome, there are some treatments available, such as vitrectomy (a surgical procedure to remove the vitreous gel), but these are usually reserved for severe cases due to the risks involved.

In summary, while it can be disheartening to deal with floaters at a young age, especially with mild myopia, they are often a normal part of the aging process of the eye and not necessarily indicative of a serious problem. It's essential to keep an open line of communication with your eye care professional and report any changes in your vision. Remember, you're not alone in this experience, and many people have floaters without any significant issues.
