Floaters are small shapes—dots, threads or cobwebs—that move with your eye’s motion. They’re caused by tiny clumps in the vitreous, the gel filling your eye. As the vitreous naturally shrinks and detaches with age (posterior vitreous detachment), these shadows may appear.
Flashes occur when the vitreous tugs on the retina, often appearing as brief light streaks, especially in dark environments. While usually benign, they may signal more serious issues such as inflammation, bleeding, retinal tears, or impending detachment.
Diagnosis
Your eye specialist will dilate your pupil and perform a detailed eye examination to identify the cause of shadows or light flashes. This helps determine whether it’s a benign change or requires prompt intervention.
Treatment options
Observation
Most cases resolve on their own over several weeks or months.
Vitrectomy Surgery
Recommended only if symptoms persist and significantly impair vision. It involves removing the vitreous gel and replacing it with a saline solution. While effective, the procedure carries risks—such as elevated eye pressure, retinal injury, infection, or new floaters—and is considered when the benefits outweigh the risks.
Most spots and flashes are harmless and resolve naturally. However, if you experience a sudden surge of them or they affect your vision, prompt assessment from our specialists ensures your eye health remains protected.
