Hypotony and Low Eye Pressure

If you notice an unexplained loss of acuity in the center of your visual field, you may be experiencing classic signs of eye pressure problems. The amount of pressure within the eye – called intraocular pressure – is an important factor in overall eye health.

For the eyes to stay healthy, pressure must be neither too high nor too low.

Unfortunately, the pressure within the eyes can change suddenly and for reasons that are not always obvious. One of the best-known complications of eye pressure change is glaucoma, which is characterized by damage to the optic nerve caused by high pressure.

When pressure is too low, it is referred to as hypotony.

What Are the Causes of Low Eye Pressure?

Hypotony can appear in one or both eyes. When only one eye is affected, the most likely issue is recent trauma to the eye, including surgery. Incisions may cause leakage, which temporarily lowers pressure until the wound is completely healed.

If there is no obvious insult to the affected eye, retinal detachment may be occurring. Likewise, there’s a chance the eye is inflamed – from internal injuries, infection or other sources. Systemic causes should be investigated.

Pressure may return to normal in the course of time. However, it should be treated proactively, especially if there have been noticeable changes in vision. Damage to the eye caused by pressure changes is typically permanent. The sooner treatment occurs, the better.

Hypotony Treatment

Treatment for Low Eye PressurePrompt treatment is essential to prevent hypotony maculopathy, distortion in the acuity of central vision brought on by low eye pressure. A physical examination will be conducted to measure the intraocular pressure, which is less than 6.5mm Hg for those experiencing hypotony.

Patients with hypotony do not experience any pain. However, it may be necessary to use several different diagnostic devices to isolate the cause of hypotony. Tumors, inflammation and other causes must be sought and ruled out.

Vision Care Specialists

At Vision Care Specialists, we are experienced in many treatment approaches depending on your diagnosis. Placement of an oversized contact lens, injection of blood – which promotes healthy scarring – and various suturing techniques can all be used to repair eye damage.

Whatever intervention is chosen, it should positively affect intraocular pressure immediately.

If you suspect hypotony, don’t wait. The sooner you take action, the better the results. Contact Vision Care Specialists to learn more or set an appointment. Find an eye care specialist near you.
