What are floaters?
Floaters, also called myodesopsias, are small spots or threads that appear in the field of vision. They move when the eye moves and are especially noticeable against a bright background, such as a blue sky or a white sheet of paper.
Common causes
Floaters are often related to natural changes in the vitreous, the gel-like substance inside the eye. With age, the vitreous can liquefy and partially detach from the retina, causing these small shadows to appear. They can also result from eye injuries, inflammation, or, more rarely, retinal tears.
When to consult an eye doctor?
It is important to see an eye doctor promptly if floaters appear suddenly or are accompanied by flashes of light or loss of vision. These symptoms may indicate a retinal detachment or tear, a medical emergency that requires immediate treatment.
Treatment options
In most cases, floaters are harmless and require no treatment. Patients often adapt to their presence over time. In more bothersome cases, laser treatment or a vitrectomy may be considered under specialized medical supervision.
Prevention and tips
Although not all floaters can be prevented, protecting the eyes from trauma and having regular eye exams helps detect complications early.
