Glaucoma: Symptoms, Causes, Treatment | Eye-Q: Glaucoma is a progressive eye condition that can lead to irreversible vision loss if left untreated. It often develops slowly and without noticeable symptoms in its early stages, which is why regular eye exams are crucial for early detection. Symptoms of glaucoma may include peripheral vision loss, tunnel vision, blurred vision, halos around lights, severe eye pain, nausea, and vomiting in acute cases. However, in many instances, individuals may not experience any symptoms until significant damage has already occurred. The primary cause of glaucoma is increased pressure within the eye, known as intraocular pressure (IOP), which can damage the optic nerve. The optic nerve is essential for transmitting visual information from the eye to the brain. Several factors contribute to elevated IOP, including genetics, age, ethnicity (African Americans and Hispanics are at higher risk), and underlying medical conditions like diabetes and hypertension.
