Glaucoma refers to an eye disease that causes irreparable damage to the optic nerve, thereby leading to a complete loss of vision. The optic nerve transmits the electrical impulse from the retina of the eye to the brain to generate vision. Impairment of this nerve results in major vision problems, even causing blindness.

Often, there are no prominent symptoms of glaucoma until it has affected the eye drastically. Eye problems that are not corrected with lenses or glasses might be an indication of glaucoma. Open-angle glaucoma symptoms can be insignificant and not noticed by the patient. But in closed-angle glaucoma, there is often redness of the eye, blurred vision, etc.
Acute glaucoma symptoms include poor night vision and frequent power changes. The symptoms of glaucoma are variable and often associated with nausea, headache, pain in the eye, dark spots in front of the eye, excessive tearing, etc.
