Glaucoma is characterized by a blockage of the aqueous humor, the fluid which normally drains from the front part of the eye. As the internal pressure of the eye increases, the optic nerve is compressed, eventually causing the death of nerve cells and possible permanent vision loss.

Effects of Glaucoma

  • Decreased Contrast Sensitivity
  • Night Blindness
  • Decreased Response to Magnification
  • Loss of Peripheral Vision
  • Increased Illumination Requirements
