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.
