Hello, Zhang Yongchang. Thank you for reaching out with your concerns regarding the floaters in your right eye. It’s understandable to feel uneasy when experiencing new visual phenomena, especially when they manifest as unusual shapes like the ones you described.

Eye floaters, or "muscae volitantes," are common and typically harmless. They are small clumps of gel or cells that form in the vitreous humor, the clear gel-like substance that fills the inside of your eye. As we age, the vitreous can become more liquid and may pull away from the retina, leading to the formation of these floaters. The shapes can vary widely, including spots, threads, or, as in your case, shapes resembling intertwined worms.

The fact that you mentioned these floaters are transparent and do not affect your vision is a good sign. Floaters are often more noticeable against bright backgrounds, such as a clear sky or a white wall, which might explain why you are more aware of them in certain situations. While they can be annoying, they are usually benign and do not indicate a serious underlying condition.

However, there are a few important considerations to keep in mind. If you notice a sudden increase in the number of floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, it could indicate a more serious issue, such as a retinal tear or detachment. In such cases, it is crucial to seek immediate medical attention from an eye care professional.

In your situation, since you have been experiencing these floaters for about a week and they have not worsened or affected your vision, it is likely that they are a normal part of the aging process or a benign condition. Nevertheless, it is always wise to have a thorough eye examination, especially if you have any concerns. An eye doctor can perform tests, including a dilated eye exam, to ensure that your retina is healthy and that there are no other underlying issues.

In terms of management, there are no specific treatments for floaters. Many people find that they become less noticeable over time as the brain learns to ignore them. However, if they become particularly bothersome, some options like vitrectomy (a surgical procedure to remove the vitreous gel) or laser treatment exist, but these are typically reserved for severe cases due to the risks involved.

In summary, while floaters can be unsettling, they are often a normal occurrence. Keep an eye on any changes in your symptoms, and do not hesitate to consult with an eye care professional if you have any concerns. Regular eye check-ups are essential for maintaining eye health, especially as we age. Take care of your vision, and I hope you find reassurance in knowing that floaters are a common experience for many individuals.
