Eye floaters are small moving spots that show up in the field of vision. They may appear as black or gray dots, squiggly lines, strings, or cobwebs. They tend to be most noticeable when staring at a solid light-colored background, such as blue sky or white paper. While they can be annoying, they are harmless, and most people learn to ignore them. They normally don't interfere with vision, and sometimes they diminish over time. Eye floaters occur most often in those between 50 and 75 years of age, especially those who are nearsighted or have had cataract surgery. Once eye floaters develop they don't go away, but they can improve or change.
As a person ages, a jelly-like substance called vitreous inside the eyes becomes more liquid. When that happens, fibers within the vitreous clump together and form small shadows on the retina, which are seen as eye floaters. Eye floaters usually are harmless, but those who experience a sudden increase in the number of eye floaters along with flashes of light, pain, or a loss of peripheral (side) vision should see a doctor immediately, as the symptoms could be a sign of a more serious condition.

As part of the UAB Medicine academic medical center, Callahan is actively involved in ongoing research and clinical trials.
