“Knowing you have glaucoma is one of the most important factors in treating the disease and preventing vision loss,” he said. “So many people are losing their sight and simply do not realize it. Glaucoma is a treatable disease. Vision loss can be minimized. Those who are potentially at risk must take the first step and get an eye exam.”
