Hello! Thank you for your thoughtful questions regarding floaters, or "myodesopsia," which can indeed be a source of concern for many individuals. Let’s address your inquiries one by one, providing clarity and guidance based on current medical understanding.

1. Causes of Floaters: Floaters 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 perception of floaters. While it’s true that many people experience floaters as they age, it’s not uncommon for younger individuals, including children and teenagers, to notice them as well. The presence of various shapes, such as spider webs or strands, can be alarming, but if your eye doctor has assessed your condition and deemed it normal, it is likely not a cause for concern. However, if you notice a sudden increase in floaters or flashes of light, it’s essential to seek immediate medical attention, as these could be signs of retinal detachment.

2. Reduction of Floaters Over Time: Research indicates that many people do experience a decrease in the perception of floaters over time. This can occur as the brain adapts to the presence of floaters, effectively filtering them out of conscious awareness. However, this does not mean that the floaters themselves disappear; rather, they may become less bothersome.

3. Distortion Associated with Floaters: The phenomenon you describe, where objects appear distorted when floaters pass through your line of sight, is not uncommon. This distortion can occur due to the way light interacts with the floaters as they move across your field of vision. The vitreous gel can create a refractive effect, similar to how heat waves distort the appearance of objects in the distance. If this distortion is temporary and resolves quickly, it is generally not a cause for concern. However, if you experience persistent or worsening distortion, it’s advisable to consult with an eye care professional.

4. Exercise and Eye Pressure: Engaging in regular physical activity, such as running, is beneficial for overall eye health and can help lower intraocular pressure, which is particularly important for individuals at risk for glaucoma. While there is a theoretical concern that vigorous exercise could lead to retinal traction, the risk is generally low for most individuals. If you have pre-existing conditions or concerns about retinal health, it’s best to discuss your exercise routine with your eye doctor, who can provide personalized advice based on your specific situation.

5. Concerns About Medication Side Effects: Regarding the medication you mentioned, it’s crucial to discuss any potential side effects with your prescribing physician. While some medications can have ocular side effects, the actual risk of retinal detachment from specific medications varies. Your doctor can provide you with the most accurate information based on your medical history and the specific medication you are taking. If you have concerns about the side effects, do not hesitate to bring them up during your next appointment.

In summary, while floaters can be bothersome, they are often a benign condition, especially when assessed by a healthcare professional. It’s essential to maintain regular eye examinations and communicate any changes in your symptoms to your eye doctor. They can provide reassurance and guidance tailored to your individual needs. If you have any further questions or concerns, please feel free to reach out. Take care!
