Fuch’s Corneal Dystrophy is a genetic condition that is found in about 4% of the population.  A person is usually asymptomatic until middle age or later.  Some early symptoms may include photophbia or increased glare.  Later the corneal can swell or fill up with too much fluid causing both decreased vision and discomfort.  The inside layer of cells in the corneal called ENDOTHELIUM are responsible to keeping the cornea in a dehydrated state.  In Fuch’s Dystrophy these endothelial cells do not function as well as they should, and signs of this can be detected on eye examination.  When endothelial cells become too weak or too few to do their job, the corneal collects too much fluid becoming thicker and starts to turn white or bluish.  Visual symptoms are decreased vision, hazy vision like looking through a fog, halos around lights at night, decreased reading vision and blurry vision on awakening that improves as the day goes on.  If the swelling is severe the vision can be bad enough to prevent driving and reading.  Fortunately there are wonderful techniques like Endothelial Keratoplasty (DSAEK/DSEK/PLK) that can restore vision in people with Fuch’s Dystrophy.
