Angle Closure Glaucoma is a type of eye condition that occurs when the drainage angle of the eye becomes blocked. This blockage prevents fluid from leaving the eye, leading to a rapid increase in intraocular pressure. Symptoms may include severe eye pain, headache, nausea, and blurred vision. This condition can develop suddenly, often requiring immediate medical attention to prevent permanent vision loss. Treatment options may include medications to lower eye pressure, laser therapy, or surgery to create a new drainage pathway. Early detection and management are crucial for preserving vision.
