Difference between Ocular Hypertension and Glaucoma

Ocular hypertension and glaucoma are two different conditions that can affect the eyes. Ocular hypertension is when there is a high pressure in the eye, but no damage has been done to the optic nerve. Glaucoma is when the pressure damages the optic nerve, which can lead to vision loss. While ocular hypertension can progress to glaucoma in some cases, not everyone with ocular hypertension will develop glaucoma. It is important to know the difference between these two conditions and how they can impact your vision.

What is Ocular Hypertension?

Ocular hypertension is a condition in which the pressure inside the eye, also known as intraocular pressure (IOP), is higher than normal. It is important to monitor and treat this condition because high IOP can lead to damage of the optic nerve and ultimately result in vision loss or even blindness. Ocular hypertension does not always cause symptoms, so regular check-ups with an eye doctor are crucial for early detection and treatment. Ocular hypertension can often be managed through prescription eye drops, but in some cases, surgery may be necessary. It is important to work closely with your ophthalmologist to monitor and manage ocular hypertension for optimal eye health.

What is Glaucoma?

Glaucoma is a group of eye diseases that gradually steal sight without warning or symptoms. It is often associated with a buildup of pressure inside the eyeball, causing damage to the optic nerve. This can result in vision loss and even blindness if not treated properly. Glaucoma is the leading cause of irreversible blindness worldwide, affecting over 3 million Americans alone.

There are two main types of glaucoma: primary open-angle glaucoma and angle-closure glaucoma. Risk factors for developing glaucoma include age, family history, race/ethnicity, high intraocular pressure, and medical conditions such as diabetes and hypertension.

Difference between Ocular Hypertension and Glaucoma

  • Ocular Hypertension and Glaucoma are both eye conditions that involve increased pressure within the eye. However, Ocular Hypertension refers to elevated intraocular pressure without any damage to the optic nerve or resulting vision loss.
  • On the other hand, Glaucoma is a condition where there is damage to the optic nerve and corresponding vision loss, often due to chronically high intraocular pressure. Ocular Hypertension can potentially progress into glaucoma if left untreated, but not all cases of Ocular Hypertension will result in glaucoma.
  • Treatment for Ocular Hypertension may include monitoring of intraocular pressure and possible medications or surgery to lower it, while treatment for glaucoma typically focuses on preventing further damage to the optic nerve and preserving remaining vision. It is important to have regular eye exams, as early detection and treatment can help improve outcomes for both Ocular Hypertension and Glaucoma.


Ocular hypertension is a condition where the pressure inside of your eye is high, but it typically doesn’t cause any damage. Glaucoma, on the other hand, is a serious eye disease that can lead to vision loss if not treated. It’s important to know the difference between these two conditions and get regular checkups so you can catch glaucoma early if you do have it.
