What eye pressure is safe?

A safe range for eye pressure, also known as intraocular pressure (IOP), is between 11 and 21 millimeters of mercury (mmHg).

Understanding Intraocular Pressure

Intraocular pressure (IOP) refers to the fluid pressure inside your eye. Maintaining this pressure within a healthy range is essential for proper eye function.

Why is Eye Pressure Important?

• Shape and Function: Proper eye pressure helps maintain the globe's spherical shape. This is crucial for clear vision.
• Nourishment: The pressure ensures that the eye receives adequate nutrients.
• Drainage: IOP helps in the circulation and drainage of the aqueous humor, the fluid inside the eye.

Normal Range for Eye Pressure

As mentioned in the references, the normal range for eye pressure is 11 to 21 mmHg.

• This is measured using a tonometer by your eye care specialist.
• The measurement uses the same units (mmHg) as blood pressure readings.
• Pressures within this range are generally considered healthy.

What is Ocular Hypertension?

If your eye pressure consistently exceeds 21 mmHg, you may have a condition called ocular hypertension.

Characteristics of Ocular Hypertension:

• Elevated Pressure: IOP is consistently higher than 21 mmHg in one or both eyes, as determined by at least two visits to an eye care professional.
• Not Glaucoma: It's important to note that ocular hypertension is not the same as glaucoma, but it is a significant risk factor.
• Risk: Ocular hypertension puts you at an increased risk of developing glaucoma, a serious eye condition.

Regular Eye Checkups

• Importance: Routine eye exams, including pressure checks, are vital for monitoring eye health.
• Detection: These exams help detect and manage ocular hypertension or glaucoma early.
• Prevention: Early detection and management can help prevent vision loss.
