Flashes & Floaters


Floaters are small specks that you see moving in your field of vision. They are in fact tiny particles that float around inside the vitreous, the clear jelly-like substance that fills the inside of the eye. We see them as spots, strands, webs or various other shapes because they cast shadows on the retina as light enters the eye. They are more noticeable when looking at a blank background such as a blue sky or white wall.


For most people, floaters occur with age as the vitreous gel shrinks and changes consistency. Eye injury or breakdown of the vitreous gel may also cause spots and floaters.


If you suspect that you have floaters, be sure to schedule an appointment with Dr. Cunningham to make sure that your condition isn’t serious. Seeing the spots without any other symptoms such as flashes of light or lightening streaks is usually not problematic. If however you are also experiencing flashing lights, you could be having a more serious problem involving the retina and this warrants immediate attention. Most floaters are harmless but annoying, and they usually become less noticeable over time. Only in rare instances are floaters surgically removed.
