It is not uncommon for healthy eyes to notice spots or clouds that pass across your field of vision. These are called floaters and they may take a number of shapes and are most apparent when looking at a solid background. They are the shadow of small clots of gel or cells in the fluid that composes the inside of the eye. While they may be harmless and indicate no internal problems, floaters and spots may also indicate a larger health issue, such as a detached retina. Dr. Dunn will determine if your floaters and spots are of the normal, harmless variety or if they are indicative of a more serious health problem. There are now homeopathic remedies that help to eliminate floaters. Contact Dr. Dunn for additional information.
If you experience shimmer lights or blanked out spots in both eyes for up to 20 minutes, you may be experiencing a spasm of vessels in the brain, more commonly known as a migraine. These shimmers or heat waves are caused by the vision center of your brain not getting enough oxygen and can be followed by severe migraine headaches, or they can also occur without the headache and are called ophthalmic migraines. Research has shown that repeated migraine headaches may put you at a higher risk for strokes. Contact Dr. Dunn for information on how to reduce the frequency of migraines and to shorten the duration of common migraines when they occur.
