An illness that targets the optic nerve (which also happens to be a major nerve when it comes to vision), the condition of glaucoma is defined by a specific pattern around progressive damage to this nerve. The optic nerve obtains impulses that are light-generated, via the retina and transfers signals to the brain. The illness starts with minor loss to the peripheral (side vision); however, if it goes undiagnosed and thus untreated an individual can lose central vision, and go blind.
Generally (but not always), glaucoma can be linked to elevated pressure to a person’s eye. Mostly, it is this elevated pressure that is behind the damage around the optic nerve/eye. With that said, some patients can develop glaucoma via normal eye pressure; however, this form of the illness is thought to be caused due to inadequate blood flow regulation to the optic nerve.
As the second leading cause of irreversible blindness across the world, up to six million people experience blindness in both eyes from glaucoma.
There are different types of glaucoma, and therefore, the condition can present a variety of symptoms based under these “types”. It’s important to note that most glaucoma patients can be classified as open-angle (chronic, long-term) or angle-closure (closed angles, which can also include chronic and acute/sudden examples of the condition).
Below are 10 symptoms of glaucoma.
When your vision is clear and sharp, the world is your oyster! You can easily read traffic signs, a book, labels on bottle or cans, and explore your surroundings; however, blurred vision can make an individual feel as if a filter has been placed over their eyes – as if the world around you is a camera lens that is no longer in focus.
Blurred vision can affect a part of a patient’s vision or their entire line of sight; it can disrupt one’s field of vision or peripheral vision, and it can also (and generally) only blur in one eye. Many who suffer from glaucoma described blurred vision as “dim vision” or simply “cloudy” vision.
Interestingly enough, as of 2020, there are approximately 78 million people worldwide living with glaucoma.
