It is often called the “slow silent killer” of vision that leads to blindness.
Glaucoma is a group of eye diseases that gradually steal sight without any warning. Glaucoma does not have any symptoms until serious damage has already been done. The optic nerve is the nerve that connects your eyes to your brain so that you can process what your eyes see. When glaucoma damages the nerve, you lose peripheral vision. While there is no cure for glaucoma, medication, laser treatment, or surgery can slow the vision loss. The earlier we start treatment, the better we can manage the disease. While having a high intraocular pressure is a risk factor for glaucoma, there are other things that can cause it including previous trauma or systemic diseases. And there is even a type of glaucoma where the intraocular pressure is normal. The only way to monitor yourself for glaucoma is to see your eye doctor for regular comprehensive eye examinations.
