Eye floaters are tiny spots, specks, lines or shapes that enter into your field of vision, appearing to float in front of the eye. They may seem like distant objects, but they are actually the shadows of cells and fibres inside the vitreous, or gel-like portion of the eye.
Floaters are most often isolated occurrences that are a perfectly normal part of vision. However, if they become more frequent, and are accompanied by eye flashes – bursts or streaks of light similar to the “stars” you may see after taking a blow to the head – this may be a sign of an impending retinal detachment. This is very serious and should be brought to the attention of an eye care professional.
What Causes Eye Floaters and Eye Flashes?
The vitreous gel may shrink, forming tiny clumps in the eye. These clumps cast shadows onto the retina, and the resulting forms and shapes are referred to eye floaters.
Sometimes during the process of the vitreous shrinking, it remains partially attached to the retina, and tugs on it. The resulting movement of the retina’s nerve cells can cause eye flashes.
Symptoms of Eye Floaters and Eye Flashes
Treatments for Eye Floaters and Eye Flashes
Most of the time, eye floaters are not a sign of anything harmful, and simply looking up or down can move them out of your field of vision.
However, if they are accompanied by eye flashes, it may be a sign of retinal detachment, a serious condition that can lead to severe vision loss. For this reason, it’s recommended that anyone who experiences eye flashes schedule an exam with their eye care professional immediately.
