Sudden Increase in Floaters: Should You Be Concerned? - Ophthalmology

More Info

---

Experiencing a sudden increase in floaters, especially when accompanied by flashes of light, can indeed be a cause for concern, particularly for individuals with a history of eye conditions such as myopia (nearsightedness) or those who have undergone eye surgery, like retinal laser treatment. Floaters are tiny spots or strands that drift through your field of vision, and while they are common and often harmless, a sudden increase in their number can indicate potential issues with the retina.

In your case, the fact that you have a history of deep myopia and have had laser surgery on your right eye raises the stakes. Myopia is associated with a higher risk of retinal detachment, especially as the vitreous gel inside the eye shrinks and pulls away from the retina, which can lead to the symptoms you are describing. The flashes of light you are experiencing, known as photopsia, can occur when the vitreous pulls on the retina, potentially leading to tears or detachment.

The episodes you described occurring under bright lighting conditions and during times of stress or poor sleep may not be directly related to the underlying issue, but they could exacerbate your perception of floaters and flashes. Stress and fatigue can affect your overall visual perception, making you more aware of these symptoms.

Given that you have experienced these symptoms twice and considering your medical history, it is advisable to seek immediate medical attention, even if it means finding a way to consult with an eye care professional despite the challenges posed by the pandemic. An eye examination, particularly a dilated fundus examination, is crucial to rule out any serious conditions such as retinal tears or detachment. These conditions can lead to significant vision loss if not addressed promptly.

In summary, while floaters are often benign, a sudden increase in their number, especially when accompanied by flashes of light, warrants a thorough evaluation by an eye specialist. It is better to err on the side of caution, particularly given your medical history. If you experience any additional symptoms such as a curtain-like shadow over your vision, a sudden decrease in vision, or persistent flashes, seek emergency care immediately. Your vision is invaluable, and timely intervention can make a significant difference in preserving it.
