Glaucoma is a group of eye disorders characterized by increased pressure inside the eye, leading to damage of the optic nerve. This condition often begins by affecting peripheral vision, making it difficult to detect in the early stages. It is important to consult with an eye doctor in Santa Ana for diagnosis and treatment, as untreated glaucoma can result in blindness. Glaucoma is the second leading cause of blindness in the United States, with millions of Americans affected.
