Floaters: Concerns About Their Location and Behavior - Ophthalmology

Location of floaters?


Three weeks ago, I suddenly noticed four new floaters below my right eye, one of which is a larger dark shadow.
I have undergone a retinal examination, and the fundus appeared normal.
Previously, my floaters were mostly in the left and upper areas and did not typically interfere with my visual axis.
Regardless of how I move my eyes, when I look upward, these new floaters seem to float up.

1) Is it normal for floaters to be this close to the visual center?
2) Is it possible for floaters that are already in the vitreous to settle and drift away from the visual center?
3) Is it possible for floaters to become less noticeable over time? Will larger floaters be less likely to become less noticeable?

Hello: 1.
It is possible.
2.
If there are changes in the vitreous body, it is possible.

It is possible; larger ones may sometimes decrease in size.
Initially, it can be concerning, but over time, you will adapt to the situation and there is no need to worry.

More Info


Floaters, or "muscae volitantes," are small spots or strands that drift through your field of vision. They are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the formation of floaters. Your concerns about the recent appearance of floaters in your right eye, particularly their location and behavior, are valid and warrant further discussion.

1. Location of Floaters: It is not uncommon for floaters to appear closer to the center of your visual field, especially if they are new. Floaters can vary in size, shape, and location, and their proximity to the visual axis can change based on the dynamics of the vitreous humor. While you may have previously experienced floaters in different areas of your visual field, the appearance of new floaters near the center is not necessarily abnormal. However, it is essential to monitor them, especially if they are accompanied by other symptoms such as flashes of light or a sudden increase in the number of floaters, as these could indicate a more serious condition like a retinal tear or detachment.

2. Movement of Floaters: Floaters can indeed settle or drift away from the center of your vision over time. The vitreous humor is not static; it can change, and floaters may move as the vitreous gel continues to liquefy or as the eye moves. However, the behavior of floaters can vary from person to person. Some floaters may remain in the visual axis for an extended period, while others may gradually drift out of the way. It is also possible for floaters to become less noticeable as your brain adapts to their presence, effectively filtering them out of your conscious perception.

3. Fading of Floaters: Floaters can become less prominent over time, but this is not guaranteed. Some floaters may fade or become less noticeable as they settle or as the vitreous gel changes. However, larger floaters may not necessarily become less visible; in fact, they might remain prominent because of their size and density. The perception of floaters can also be influenced by lighting conditions and the contrast of the background against which they are viewed.
In summary, while the appearance of new floaters, especially near the center of your vision, can be concerning, it is essential to remember that they are often a benign condition related to the aging process of the eye. Regular eye examinations and monitoring any changes in your symptoms are crucial. If you notice any sudden changes in your vision, such as an increase in floaters, flashes of light, or a shadow in your peripheral vision, you should seek immediate medical attention, as these could be signs of a more serious issue.
If you have ongoing concerns about your floaters or if they are significantly impacting your quality of life, discussing these issues with an eye care professional can provide you with personalized advice and reassurance. They may also explore treatment options if necessary, although many people learn to live with floaters without any intervention.
