Glaucoma - Symptoms

What are the different types of glaucoma and their symptoms?

  • Open-angle glaucoma
    Open-angle glaucoma accounts for the majority of glaucoma in most countries. It often has no symptoms and progresses slowly. The rise in intraocular pressure is slow and painless.
  • Closed-angle glaucoma
    Angle-closure glaucoma can either be acute or chronic. Acute angle-closure glaucoma is characterised by a sudden, dramatic increase in intraocular pressure. This can cause severe eye pain, redness, blurred vision and the appearance of haloes around lights. Headaches, nausea and vomiting may follow. This emergency requires prompt treatment. The chronic form may show no symptoms, as in open-angle glaucoma.
  • Congenital glaucoma
    Congenital glaucoma is rare and occurs at birth. Enlargement of the infant’s eyes, corneal haze, tearing and unusual light sensitivity are symptoms that warrant an eye examination.
  • Secondary glaucoma
    Secondary glaucoma may be caused by conditions such as poorly controlled diabetes, inflammation of the eye, tumours, previous eye surgery, injuries or cataracts in their advanced stages, or the use of steroid medications on the eye.
