Capt. Frank Cumbie, 1st Helicopter Squadron pilot, sits at a slit lamp while his eye is examined. The best way to know if you are at risk for glaucoma is to have a baseline eye exam that includes at minimum a pressure check and eye dilation. A dilated exam is important because it allows your doctor to visualize the optic nerve to look for changes that can occur in glaucoma. (U.S. Air Force photo/Senior Airman Preston Webb)
