Intraocular Pressure (IOP)

What is Intraocular Pressure (IOP)?

Intraocular Pressure (IOP) is the pressure of the fluid in the eye. It is an important factor to consider in the diagnosis and treatment of glaucoma and other eye diseases. The normal range of IOP is about 10 to 20 mmHg. If the IOP is too high, it can cause damage to the optic nerve and impact vision. Conversely, if the pressure is too low, it can put the eye at risk for hemorrhage and vision loss.

Causes of Elevated IOP

The most common cause of elevated intraocular pressure is increased production of aqueous humour in the eye. This can occur due to certain eye diseases or environmental causes such as high altitude. Other causes may include in article inflammation, and use of steroids or other medications.

What Are The Symptoms of High Intraocular Pressure?

High intraocular pressure is usually asymptomatic, which is why regular eye exams are recommended for those who are at risk for glaucoma or other conditions that can lead to high IOP. If the pressure is left unchecked, it can cause a range of symptoms, which may include:

  • Headache
  • Eye redness
  • Eye pain
  • Blurry vision
  • Seeing spots or halos around lights
  • Nausea or vomiting

How is High Intraocular Pressure Treated?

High intraocular pressure can be treated in a variety of ways. The most common is the use of eyedrops to reduce the production of aqueous humour. Laser treatments and surgery may also be used in some cases. It is important to discuss all treatment options and select one that is right for you and your specific condition.
