Glaucoma cannot be cured, but some options available for treatment include surgery, oral medication, eye drops and research treatment. Glaucoma is a group of conditions that cause damage to the nerve that connects the eye and brain. Without proper treatment, glaucoma can cause total permanent blindness within a few years, notes WebMD.
Glaucoma is a result of pressure build up within the eye often referred to as intraocular pressure. Without proper management, this pressure may build to a point of damaging the optic nerve which is responsible for relaying images to the brain. The two most common types of glaucoma are acute angle-closure and primary angle-closure glaucoma.
Some symptoms of primary angle-closure glaucoma include a gradual loss of peripheral vision and tunnel vision at a later stage. Acute angle-closure glaucoma is characterized by painful sensations of the eye, nausea, appearance of halos around lights, blurred vision, reddening of the eyes and a sudden development of visual disturbance.
Doctors diagnose this condition by reviewing patient medical history and carrying out various eye examinations. Doctors often focus on reducing the pressure in the eye as a way of providing relief, notes Mayo Clinic. If the condition is too severe, doctors may use surgery as a way of treating it. For mild cases, oral medications and eye drops may be effective. There are also clinical tests that can offer relief to patients with the condition.
