Glaucoma is a leading cause of blindness and visual impairment in the United States. Our routine annual eye exam can detect the disease. With early detection and treatment, glaucoma can usually be controlled and your vision preserved. To detect glaucoma, your physician will test your visual acuity, visual field, dilate your pupils and test the pressure in your eye. Glaucoma is a slow, progressive disease, often without any pain or discomfort. Therefore, it has often progressed by the time it is diagnosed. Annual routine eye exams are therefore recommended. Various treatments to control glaucoma include eye drops, laser surgery and conventional surgery.
