What are the symptoms and causes of glaucoma

Glaucoma is an eye condition that gradually damages the optic nerve, often due to increased pressure inside the eye. Many people may not notice early changes because the disease can progress slowly and silently. It is especially common in older adults, though anyone can develop it depending on genetics and eye health. Understanding What are the symptoms and causes of glaucoma is important because early detection can help protect vision. Symptoms may start with subtle blind spots or difficulty seeing in low light, eventually leading to peripheral vision loss. Some forms, like acute angle-closure glaucoma, can cause sudden eye pain, redness, blurred vision, or nausea. Causes often include elevated eye pressure, but poor blood flow to the optic nerve and family history also play major roles. Medical conditions such as diabetes or severe nearsightedness can increase risk as well. Regular eye exams help identify early signs before noticeable vision loss occurs. Treatment may involve prescription eye drops, laser therapy, or surgery to lower pressure. Protecting eye health early can significantly slow the progression of this serious condition.
