No, a reading of 7 mm Hg is generally considered low eye pressure, and may require further investigation.
According to the reference provided, approximately 90% of the general population has an eye pressure between 8 and 21 mm Hg. Therefore, a pressure of 7 mm Hg is considered to be below the normal range.
Understanding Eye Pressure
Eye pressure, also known as intraocular pressure (IOP), is the fluid pressure inside the eye. This pressure is essential for maintaining the shape of the eye. It's important to note that ideal eye pressure can vary slightly from person to person.
Here's a breakdown:
| Eye Pressure Category | Range (mm Hg) |
|---|---|
| Normal | 8 - 21 |
| Low | Less than 8 |
- Reference Point: The reference states that low eye pressure is generally defined as less than 8 mm Hg.
Why Low Eye Pressure is Important
While high eye pressure is often associated with glaucoma, low eye pressure can also be problematic. Having a low eye pressure could indicate several potential underlying issues, including:
- A leak in the eye.
- Eye inflammation.
- Issues with the eye's ciliary body, which produces fluid.
It's crucial to have regular eye exams to monitor your IOP. If your pressure is consistently below 8 mm Hg, your eye doctor can help determine the cause and recommend appropriate treatment if necessary.
