Glaucoma is characterized by a group of eye diseases that cause damage to the optic nerve and visual field. The human eye is filled with a clear liquid which is made continuously and then drained away, always keeping the same amount of liquid in the eye. When the opening that allows the liquid to drain is closed, more and more liquid will build up in the eye increasing the pressure.
Over time, this increased pressure can damage the eye and cause reduced vision and then blindness which cannot be reversed. It's very common for glaucoma to present with no symptoms, and once vision is lost, it's permanent. This is why it's so critical to get regular eye screenings to detect the eye condition as early as possible.
In communities around the world, our long-term goal is to increase the quality of eye care for everyone, including better access to screenings and capacity in managing glaucoma once it's diagnosed.
