Glaucoma is a multi-factorial, complex eye disease with specific characteristics such as optic nerve damage and visual field loss.

While increased pressure inside the eye (called intraocular pressure or IOP) is usually present, even patients with normal range IOP can develop glaucoma.

There is no specific level of elevated eye pressure that definitely leads to glaucoma; conversely, there is no lower level of IOP that will absolutely eliminate a person’s risk of developing glaucoma.

That is why early diagnosis and treatment of glaucoma is the key to preventing vision loss.

Measuring Eye Pressure

Eye pressure is measured in millimeters of mercury (mm Hg).

Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal.

When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension.

High eye pressure alone does not cause glaucoma.

However, it is a significant risk factor. Individuals diagnosed with high eye pressure should have regular comprehensive eye examinations by an eyecare professional to check for signs of the onset of glaucoma.

Elevated IOP

A person with elevated IOP is referred to as a glaucoma suspect, because of the concern that the elevated eye pressure might lead to glaucoma.

The term glaucoma suspect is also used to describe those who have other findings that could potentially, now or in the future, indicate glaucoma.

For example, a suspicious optic nerve, or even a strong family history of glaucoma, could put someone in the category of a glaucoma suspect.

WHAT IS GLAUCOMA?

Glaucoma is an underestimated disease. Many people don’t realize the severity of glaucoma, or who is affected. Left untreated, glaucoma can cause blindness and it is the second leading cause of blindness in the world.glaucoma-example2___Source

Glaucoma is a condition in which the passages that allow fluid in the eye to drain become clogged or blocked. The amount of fluid in the eye builds up and causes elevated pressure inside the eye. The elevated pressure damages the optic nerve, which connects the eye to the brain and is the main carrier of vision information to the brain. Damage to the optic nerve results in permanent vision loss.

SYMPTOMS OF GLAUCOMA

OPEN-ANGLE GLAUCOMA

  • Most people have NO symptoms until they begin to lose vision
  • Gradual loss of peripheral (side) vision (also called tunnel vision)

 

ANGLE-CLOSURE GLAUCOMA

  • Symptoms may come and go at first, or steadily become worse
  • Sudden, severe pain in one eye
  • Decreased or cloudy vision
  • Nausea and vomiting
  • Rainbow-like halos around lights
  • Red eye
  • Eye feels swollen

 

CONGENITAL GLAUCOMA

  • Symptoms are usually noticed when the child is a few months old
  • Cloudiness of the front of the eye
  • Enlargement of one eye or both eyes
  • Red eye
  • Sensitivity to light
  • Tearing
