Many cases of glaucoma go undected and untreated before loss of vision occurs. Symptoms are usually very gradual and develop over a long period of time depending upon the type of glaucoma. In one type of glaucoma, acute angle-closure glaucoma , there are noticeable symptoms. Severe pain in the eye, headaches, nausea and vomiting, and blurred vision can occur. This type of glaucoma is rare, but very serious.
Loss of vision can occur rapidly.
There is no cure for glaucoma. If loss of vision is sustained there are no treatments available that can restore vision. If glaucoma is detected, especially in the early stages, it can be controlled. Treatments such as eyedrops, ointments, pills, laser treatment, and surgery can help to effectively control glaucoma. Eyedrops are the most common form of treatment.
