Floaters: When to Worry About Eye Symptoms - Ophthalmology

More Info

---

Floaters, or "flying spots," are common visual disturbances that many people experience, especially those with myopia (nearsightedness) or other eye conditions. They are typically caused by changes in the vitreous humor, the gel-like substance that fills the eye. As we age or due to certain eye conditions, the vitreous can become more liquid and may pull away from the retina, leading to the perception of floaters. While floaters are usually harmless, there are specific situations when they may indicate a more serious underlying issue.

In your case, you mentioned having floaters that appear as cotton-like shapes and black dots, along with a recent experience of seeing circles of light after waking up suddenly. The appearance of new floaters or a sudden increase in their number, especially if accompanied by flashes of light or changes in vision, can be concerning. These symptoms may suggest a potential retinal issue, such as a retinal tear or detachment, which requires immediate medical attention.

The fact that you have a history of myopia is relevant, as individuals with high myopia are at a greater risk for retinal problems. The sudden appearance of light flashes, especially after a period of tension or abrupt movement, can indicate that the vitreous is pulling on the retina, which can lead to tears. If you notice that these symptoms persist or worsen, it is crucial to consult an eye care professional promptly.

Regarding the sensation of seeing light spots, this could be related to several factors. It might be a visual phenomenon known as "visual snow," which can occur in certain individuals, or it could be related to the afterimages caused by bright lights or sudden changes in lighting conditions. However, if these light spots are new or have changed in frequency or intensity, it is advisable to seek a thorough examination.

In summary, while floaters are often benign, any sudden changes in your vision, such as an increase in floaters, the appearance of flashes of light, or new visual disturbances, should be taken seriously. It is essential to have regular eye examinations, especially given your myopia and the recent changes you've experienced. If you have not done so already, I recommend scheduling an appointment with an ophthalmologist who can perform a comprehensive eye exam, including a dilated fundus examination, to rule out any serious conditions and provide you with peace of mind. Remember, early detection and intervention are key to maintaining eye health and preventing potential vision loss.
