Eye Diseases


Did you know that Glaucoma is one the leading causes of irreversible blindness in the world?

  • Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina (a specialized light sensing tissue in the eye) to the brain for us to see. Glaucoma is characterized by damage to the nerve fibers of the optic nerve which will lead to blind spots in the field of vision in the early stages and eventually permanent vision loss or blindness if the entire optic nerve is damaged.
  • Glaucoma is the leading cause of blindness in the world according to the World Health Organization.
  • Glaucoma is not curable and vision loss is not reversible. Medication and/or Surgery may only stop vision loss progression.
  • Whilst some people are at a greater risk than others, anyone may get glaucoma.
  • The most common type of glaucoma usually presents with no symptoms. Vision loss beings with the peripheral (side) vision. In most cases people unconsciously compensate for this vision loss by turning their heads from side to side, thereby not noticing anything until a significant vision has been lost.
  • Early detection of glaucoma is critical to avoid vision loss associated with glaucoma. Visit your nearest SAOA Optometrist today for a full eye examination.
