Floaters: Is Vitreous Degeneration the Cause? - Ophthalmology

Hello! Thank you for your question regarding floaters and vitreous degeneration. Floaters are small spots or shapes that appear in your field of vision, often described as tiny dots, strands, or cobweb-like structures. They are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age, the vitreous can undergo degeneration, leading to liquefaction and the formation of floaters.

In your case, the progression of your symptoms from seeing floaters only in specific conditions (like looking at the sky) to noticing them more frequently in various situations (like walking or looking at screens) suggests that there may indeed be an increase in vitreous degeneration. This is a common occurrence, especially in individuals with myopia (nearsightedness), as the vitreous tends to degenerate more rapidly in those with higher degrees of myopia.

Vitreous degeneration can lead to a condition known as posterior vitreous detachment (PVD), where the vitreous pulls away from the retina. While PVD itself is generally not harmful, it can sometimes be associated with retinal tears or detachments, particularly in individuals with high myopia. Therefore, it is crucial to monitor any changes in your vision closely.

Regarding your concern about retinal thinning, while vitreous degeneration does not directly cause retinal thinning, the two can be related. High myopia can lead to changes in the structure of the eye, including thinning of the retina, which may increase the risk of retinal detachment. If you are experiencing new or worsening floaters, flashes of light, or any significant changes in your vision, it is essential to consult with an eye care professional for a thorough examination. They may perform tests such as a dilated fundus examination or optical coherence tomography (OCT) to assess the health of your retina and vitreous.

In summary, while vitreous degeneration is likely contributing to your symptoms of floaters, it is essential to rule out any potential complications, especially given your history of high myopia. Regular eye examinations and monitoring of your symptoms are vital to ensure your eye health remains stable. If you have any further questions or concerns, please do not hesitate to reach out to your eye care provider. Thank you for your inquiry, and I wish you the best in maintaining your eye health!
