Questions related to floaters?
Hello, Doctor.
I previously asked you some questions, and I went to the hospital a few days ago for an eye examination, including OCT, visual field testing, and dilation.
The doctor indicated that the results were normal, but I have elevated intraocular pressure and was advised to monitor it, and I was prescribed eye drops.
I also mentioned the increase in floaters, and the doctor said they are benign.
I have a few questions:
1.
The floaters I had before were long, moving quickly, and even when they drifted to the center of my vision, I could move my eyes to let them float away without much impact.
Recently, the new floaters are dot-like and close to the center of my visual field.
Even when I move my eyes, they don't easily drift out of my sight and don't move much.
Could this be because the vitreous is just beginning to degenerate and hasn't fully liquefied, making it harder for them to move? Floaters that have been present for a long time seem to float away more easily.
2.
Is there currently no effective method to delay the progression of floaters? Reducing eye strain and increasing the intake of nutrients necessary for eye health should be the best approach, right?
3.
I am considering getting progressive lenses with blue light filtering.
My intention for using progressive lenses is not only to block some UV rays but also to reduce the chances of seeing floaters in sunlight.
Is there a chance that this could help me notice the floaters less?
4.
It seems that the brain can ignore unimportant visual details.
Do you have any methods to train the brain to overlook bothersome floaters?
Thank you, Doctor, for clarifying these questions.
I wish you all the best and happiness every day.
Thank you!

Hello, Student Chen: 1.
Fully liquefied substances are easier to float.
2.
Currently, there is no method available.
3.
A deeper background will reduce the chances of visibility.
4.
Over time, it becomes a case of out of sight, out of mind, and there is no specific training method; it only takes time to get used to it.

More Info
Increased floaters in vision, particularly for individuals with high myopia, can be concerning and often lead to anxiety about potential underlying issues. Based on your description and the previous medical evaluations you've undergone, it seems that your symptoms are likely related to the natural aging process of the vitreous gel in the eye, known as vitreous degeneration or liquefaction.
1. Understanding Floaters: The floaters you describe, particularly the new point-like ones that are more centrally located in your vision, may indeed be a result of the vitreous gel undergoing changes. As the vitreous body ages, it can become more liquid and less gel-like, leading to the formation of clumps or strands that cast shadows on the retina, which you perceive as floaters. The older floaters that you mentioned, which are more elongated and can move away from your line of sight, may be more established in the vitreous and thus are less likely to obstruct your vision as they have settled more into the gel. The newer, point-like floaters may not move as freely because they are still in the process of settling or because they are larger and denser.
2. Management of Floaters: Unfortunately, there is currently no proven method to prevent or significantly reduce the occurrence of floaters. Maintaining good eye health through regular check-ups, a balanced diet rich in antioxidants (like vitamins C and E, omega-3 fatty acids, and lutein), and proper hydration can support overall eye health. However, these measures may not directly affect the presence of floaters.
3. Use of Glasses: Regarding your interest in getting glasses with blue light filtering and multifocal lenses, while these can help reduce eye strain and improve visual comfort, they may not necessarily reduce the perception of floaters. However, they can help you manage glare and improve your overall visual experience, particularly in bright conditions where floaters may be more noticeable. The glasses can also help in reducing fatigue from prolonged screen time, which is beneficial for your eye health.
4. Cognitive Adaptation: The brain has an incredible ability to adapt to visual disturbances. While there is no formal training to ignore floaters, some strategies can help. Engaging in activities that require focus and concentration can help shift your attention away from the floaters. Mindfulness and relaxation techniques may also assist in reducing anxiety about the floaters, allowing you to become less aware of them over time. Additionally, maintaining a positive mindset and understanding that floaters are common and often benign can help reduce the stress associated with them.
In conclusion, while floaters can be bothersome, especially when they change in nature or increase in number, it is essential to remember that they are often a benign condition, particularly in the context of high myopia and vitreous degeneration. Regular follow-ups with your eye care provider are crucial to monitor any changes and ensure that no other underlying conditions are present. 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, it is important to seek immediate medical attention, as these could be signs of retinal detachment or other serious conditions.
