What is glaucoma? Glaucoma is an eye disease that affects the optic nerve hence causing a progressive and complete vision loss. The optic nerve is the main nerve of vision; it receives light from the retina and transmits it to the brain for interpretation as vision. This type of eye disorder develops progressively; it begins with the loss of the peripheral vision and then loss of the central vision. Due to its slow development process symptoms may go unnoticed hence the condition is termed as the silent vision killer. Glaucoma blocks the drainage system of the eyes clear fluid hence leading to fluid build up and increased eye pressure. Due to this the optic nerve deteriorates and if left untreated total blindness may result.
