Glaucoma is the disease of the major nerve of vision, the optic nerve. It leads to progressive irreversible loss of vision, leading to total blindness. Glaucoma has been nicknamed the "silent thief of sight" because the loss of vision normally occurs gradually over a long period of time and is often only recognized when the disease is quite advanced. It is the second leading cause of blindness worldwide. If detected early, it is possible to prevent the disease progression.
The indications include:
• Narrowing field and tunnel vision (impaired vision)
• Intraocular pressure (pressure inside the eye)
• Visual field damage
• Clouded or haloed vision
• Rainbow halos around lights
• Red eyes
