About Glaucoma

Glaucoma is a disorder which causes optic nerve damage leading to visual field loss and is a major cause of visual impairment including decreased vision and blindness in many countries, especially in Japan and several other Asian countries. Since glaucomatous optic nerve damage and visual field defects are generally progressive and irreversible, early detection and treatment for controlling progression of damage is crucial in the treatment of glaucoma.
