Open-angle glaucoma is usually asymptomatic in the early stages, with visual symptoms developing subtly and gradually over time. The most common visual symptoms reported are needing more light, blurry vision, seeing glare, and difficulty seeing objects in peripheral vision.[1]
Angle-closure glaucoma can present chronically, often without symptoms. However, it can also present acutely, with a sudden increase in the pressure inside the eye causing symptoms that include blurry vision, reddening of the eye, intense eye pain, severe headache, and nausea and vomiting.[2]
