  • Angle-closure Glaucoma – When the fluid at the front of the eye cannot reach the angle and leave the eye, the angle gets blocked by part of the iris.  If you are suffering from this type of Glaucoma will will have a sudden increase in eye pressure leading to severe pain, nausea, redness of the eye and blurred vision.  If you have these symptons seek medical treatment immediately.
  • Congenital Glaucoma – Born with a defect in the angle of the eye that slows down the normal drainage of fluid.  The children’s vision is appears with cloudy eyes, excessive tearing and sensitivity to light.
  • Low-tension Glaucoma – Optical nerve damage and narrowed side vision occur.
  • Normal-tension Glaucoma – This type can be slowed by lowering the patients eye pressure by atleast 30% through the use of medicine.
  • Secondary Glaucoma – This type can develop following complications from other medical conditions and sometimes associated with eye surgery, eye injuries, some eye tumors and eye inflammation (uveitis).
  • Neovascular Glaucoma – A more severe form of Pigmentary Glaucoma often linked to diabetes.
