Glaucoma refers to a group of progressive diseases in which cells and fibers of the optic nerve are damaged, affecting the transmission of signals from the eye to the brain. The most common form is Primary Open Angle Glaucoma (POAG). The condition may be influenced by genes but also can be caused by other factors such as diabetes, previous eye injury, hypertension, or use of corticosteroids.
What’s troubling about glaucoma is the fact that it may exist without presenting any immediate or obvious symptoms. However, as glaucoma progresses, the condition will affect vision and can cause irreversible blindness.
People with glaucoma tend to experience one or more symptoms that may include:
- Eye pain
- Nausea and/or vomiting due to severe eye pain
- Blurry vision
- Appearance of halos around light sources
- Reddening of the eye
- Visual disturbance in low light
- Gradual loss of peripheral vision
Because there are several types of glaucoma and their symptoms are not always apparent to the patient, it’s important to have regular exams and recommended diagnostic tests done as indicated by your eye doctor. Keeping up with preventative eye care sets the stage for early detection, strategic treatment, and long-term preservation of your eyesight.
