There are two main types of glaucoma:


Open-angle glaucoma is the most common type. Most people who have open-angle glaucoma feel normal and don’t notice change in their vision in the beginning due to the initial loss of vision is of side or peripheral vision. Sharpness of vision is maintained late in the disease. As eye pressure builds, it gradually can lead to:

  • Damage of the optic nerve
  • Loss of peripheral vision
  • Blindness, if left untreated


The second most common type of glaucoma is angle-closure glaucoma. Angle-closure glaucoma, also known as narrow-angle glaucoma, can be caused by blocked drainage canals in the eye. This results in a sudden rise in intraocular pressure. A much rarer form of glaucoma, which can develop very fast and demands immediate medical attention. Symptoms of angle-closure glaucoma can include:

  • Hazy or blurred vision
  • Appearance of rainbow-colored circles around bright lights
  • Severe eye and head pain
  • Nausea or vomiting (accompanying severe eye pain)
  • Sudden sight loss
