Glaucoma is a group of eye diseases that affect the optic nerve, which connects the eye to the brain. It can usually affect both eyes to varying degrees, and one eye can develop glaucoma faster than the other.

The pupil contains a liquid called aqueous humour liquid. This liquid plays a very important role in nourishing the eye and protects the cornea against various pathogens, dust, wind, etc. When the fluid is not drained properly, an elevated pressure occurs in the eye, also known as intraocular pressure. Glaucoma develops as the increased pressure damages the optic nerve that connects the eye with the brain. If the damage continues, it is possible that it can lead to total vision loss.

Different types of glaucoma

Chronic glaucoma, the most common form that develops very slowly.

Acute glaucoma, which is a rare form, can develop rapidly and with a sudden elevated and painful pressure in the eye. Other symptoms may be sought and filtered to obtain information.


It has to be said that most people with the condition have no symptoms at all until the later stages. It is, therefore, very important to get an annual eye test.

However, if you experience any of the following, you must see medical attention:

  • Seeing halos around lights

  • Vision loss

  • Redness in the eye

  • An eye that looks hazy

  • Nausea or vomiting

  • Eye pain

  • Narrowed vision

Who is at risk?

You have a higher chance of having glaucoma if you:

  • Are of African-American, Irish, Russian, Japanese, Hispanic, Inuit, or Scandinavian descent

  • Are over 40
