Glaucoma is an eye condition caused by damage to the optic nerve, often resulting from increased pressure in the eyes. As it nearly has no symptoms in the early stages and can lead to loss of vision if not diagnosed and treated early, glaucoma takes away sight from millions of people worldwide each year.
Symptoms: Most patients do not have any symptoms in the early stages of the condition. However, if it is not treated early, gradual loss of sight starting with peripheral vision will occur – before finally resulting in permanent vision loss. In most cases of primary open angle glaucoma, medications can control the condition if it is diagnosed and treated in its early stage.
