flashes and floaters
Do you occasionally see specks or threadlike strands drifting across your field of vision? Then, when you try to
look at them, do they seem to dart away? If so, you're seeing what eye care practitioners call spots or floaters.
While almost everyone sees a few spots at one time or another, they can occur more frequently and become
more noticeable as you grow older. If you notice a sudden change in the number or size of spots, you should
contact us right away so you can be sure they are not the result of a more serious problem.
What are spots or floaters?
Spots are small, semi-transparent or cloudy specks or particles within the eye that become noticeable when they
fall within the line of sight. They may also appear with flashes of light.
The inner part of your eye is made up of a clear, jelly-like fluid known as the vitreous. As time passes the jelly-like
fluid gradually becomes more liquid in nature and cells and structural fibres detach and float around in this jelly,
resulting in the floaters that we commonly observe.
When flashes of light occur causing spots to become noticeable, it can be a result of the jelly-like vitreous
shrinking and pulling on the retina. This tugging action stimulates the retinal receptor cells to "fire," causing the
perception of light flashes.
Can these spots cause blindness?
Most spots are normal and rarely cause blindness. But spots can indicate more serious problems. If you notice
a change in the number and size of spots, a comprehensive eye examination is in order to determine the cause.
On rare occasions, vitreous detachment can cause small tears or holes in the retina. The damaged part of the
retina subsequently does not work properly and a blind or blurred spot in vision results. If untreated, retinal tears
or holes can continue to worsen and severe vision loss can result if the retina becomes detached.
How are spots diagnosed?
In a comprehensive eye examination, your eyes will be evaluated with special instruments that allow an
examination of the health of the inside of your eyes and possible observation of the spots.
This is often done after special drops are put in your eyes to make the pupils larger (called dilation) to allow a
larger view of the inside of your eyes. These procedures provide the relevant information to detect spots.
How are spots treated?
While flashes and floaters are normally not serious or treatable, they can be symptoms or signs of either
vitreous or retinal detachment. In either of these cases, treatment with lasers and/or surgical intervention may be
necessary to preserve your vision. If you notice a sudden increase or change in the number and type of spots
and floaters, contact us immediately.
