Eye floaters?

Last month, I had an eye examination and was diagnosed with floaters.
The doctor mentioned that there were no tears, but I need to continue monitoring the situation.
Recently, I've noticed that in addition to the usual floaters that look like bugs, I sometimes see straight lines appearing as well.
Are these also floaters, and is this normal? I also want to ask if floaters could be related to macular degeneration, as I am a bit concerned.
Although I checked the Amsler grid and saw that the lines are not distorted, I sometimes feel like my vision is worse, and I notice a grayish haze in front of my eyes, especially against a white background.
Could this be due to fatigue?

Hello: Floaters are a common eye symptom, typically manifested as floating objects seen in the field of vision, such as black dots, lines, or shapes resembling insects.
These images are actually projections of tiny structures within the gel-like substance (vitreous) inside the eyeball onto the retina.
Linear floaters can also be normal, especially against a bright background, where these structures may become more pronounced.
Generally, floaters do not lead to macular degeneration, as these are two distinct eye issues.
However, if you are concerned about your vision and eye condition, it is advisable to seek medical attention again to check the status of your eyes, including a macular examination.
Additionally, a grayish haze in your vision can have various causes, including eye strain, dryness, or stress.
If this symptom persists or affects your quality of life, it is also recommended to seek medical evaluation.

More Info

Floaters, or "flying spots," are a common visual phenomenon that many people experience, especially as they age. They are typically caused by changes in the vitreous gel that fills the eye, which can become more liquid and allow tiny fibers to clump together, casting shadows on the retina. While floaters are usually harmless, there are certain situations where they may indicate underlying eye health concerns.

From your description, it sounds like you have been experiencing typical floaters, including the "worm-like" shapes and now the appearance of straight lines. These can indeed be variations of floaters, and they are generally considered normal, especially if they are not accompanied by other symptoms. However, the presence of new floaters, particularly if they appear suddenly or are accompanied by flashes of light, could warrant further investigation. This is because, in some cases, they can be associated with retinal tears or detachments.

Regarding your concern about floaters being related to macular degeneration, it's important to clarify that while floaters themselves are not a direct cause of macular degeneration, individuals with high myopia (nearsightedness) are at an increased risk for both floaters and macular degeneration. High myopia can lead to structural changes in the eye that may predispose one to various retinal issues, including macular degeneration. Therefore, it is wise to maintain regular eye examinations to monitor your eye health, especially given your history of high myopia.

You mentioned experiencing a gray or hazy vision, particularly against a white background. This could be a sign of visual fatigue, especially if you have been straining your eyes or spending long periods focusing on screens or reading. Eye fatigue can lead to temporary changes in vision, including a sensation of blurriness or haze. Ensuring that you take regular breaks, practice the 20-20-20 rule (looking at something 20 feet away for 20 seconds every 20 minutes), and maintaining good lighting conditions can help alleviate these symptoms.

In terms of your overall eye health, managing your myopia and any associated symptoms is crucial. Regular check-ups with your eye care professional are essential, especially since you have a history of floaters and high myopia. They can provide tailored advice and monitor for any changes that may require intervention. Additionally, maintaining a healthy lifestyle, including a balanced diet rich in antioxidants (like vitamins C and E, lutein, and zeaxanthin), can support eye health and potentially reduce the risk of age-related eye diseases.

In summary, while floaters are typically benign, any sudden changes in your vision or the appearance of new symptoms should prompt a visit to your eye doctor. Regular monitoring and proactive eye care can help manage your concerns and maintain your eye health. If you have any further questions or notice any significant changes in your vision, do not hesitate to reach out to your healthcare provider for guidance.
