Floaters and Flashes: Insights for High Myopia Patients - Ophthalmology

Hello! Thank you for your detailed inquiry regarding your experience with floaters and flashes, particularly in the context of high myopia. As someone with significant myopia (800 degrees), it's understandable that you're concerned about any changes in your vision, especially when they manifest as flashes or floaters.

Floaters are small specks or strands that drift through your field of vision, often more noticeable against a bright background. They are typically caused by changes in the vitreous gel that fills the eye, which can become more liquid and less gel-like as we age. This process is known as vitreous degeneration or liquefaction. In high myopia, the risk of experiencing floaters and flashes increases due to the elongation of the eyeball, which can lead to changes in the vitreous and the retina.

Flashes, on the other hand, are often described as brief bursts of light that can occur when the vitreous gel pulls on the retina. This is particularly relevant for individuals with high myopia, as the retina may be thinner and more susceptible to traction. The fact that you notice these flashes when you move your eyes suddenly or look upward is consistent with this phenomenon.

Your recent examinations have indicated that your retina is healthy and that there are no signs of retinal tears or detachments, which is reassuring. The absence of significant findings during your eye exams suggests that your symptoms are likely related to the normal aging process of the vitreous rather than a more serious condition. However, it is essential to remain vigilant, as changes in vision can sometimes indicate underlying issues.

Regarding the persistence of these symptoms, it is common for floaters and flashes to be a chronic issue, especially in individuals with high myopia. While they may become less bothersome over time, they may not completely resolve. Many people learn to adapt to these visual disturbances, and they often become less noticeable as the brain learns to ignore them.

It's also important to manage any anxiety or stress related to your vision. High levels of anxiety can exacerbate the perception of visual disturbances, making them seem more prominent. Engaging in relaxation techniques, ensuring adequate rest, and maintaining a healthy lifestyle can contribute positively to your overall well-being.

If your symptoms change, worsen, or if you experience new symptoms such as a sudden increase in floaters, a curtain-like shadow in your vision, or a significant change in your vision, it is crucial to seek immediate medical attention. Regular follow-ups with your eye care provider are essential, especially given your history of high myopia.

In summary, while floaters and flashes can be concerning, they are often benign, especially in the context of high myopia. Continue to monitor your symptoms, maintain regular check-ups with your eye doctor, and don't hesitate to reach out if you have any new concerns. Your proactive approach to your eye health is commendable, and staying informed will help you manage your condition effectively. Thank you for reaching out, and I wish you the best in your eye health journey!
