What is the Eye Condition Hypotony?

Hypotony, or ocular hypotony, is a medical condition characterised by abnormally low intraocular pressure (IOP) within the eye. Intraocular pressure refers to the fluid pressure inside the eye, which is essential for maintaining the eye's shape and ensuring proper eye function. In hypotony, this pressure drops below the normal range, which can lead to various complications and affect vision.

In a healthy eye, the normal IOP values range between 10 and 21 mmHg (millimetres of mercury). When the IOP falls below 6 mmHg, it is typically defined as hypotony. Hypotony can result from several different causes, including excessive aqueous humour leakage, reduced production of aqueous humour, or increased drainage usually associated with surgical procedures or trauma to the eye.

One of the most common causes of hypotony is post-surgical complications, particularly following glaucoma surgery. Other potential causes include trauma, inflammation, or complications from other eye surgeries. Conditions such as retinal detachment or certain eye infections can also result in hypotony.

The symptoms of hypotony can vary depending on the severity of the condition but often include blurred vision, eye discomfort, and even a visible change in the shape of the eye. In some cases, low IOP can lead to more severe complications such as retinal oedema, choroidal detachment, or hypotony maculopathy, a condition where the macula (the central part of the retina responsible for central vision) becomes wrinkled, leading to distorted vision.

Diagnosing hypotony often involves a thorough examination by an eye care specialist, who may use tools such as tonometry to measure the intraocular pressure and assess the overall health of the eye. Other diagnostic procedures may include imaging tests to evaluate any structural changes within the eye.

Treatment for hypotony focuses on addressing the underlying cause of the low intraocular pressure. If the condition results from a surgical complication, further surgical intervention might be necessary to correct the problem. In cases involving trauma or inflammation, medications such as anti-inflammatory agents or antibiotics may be prescribed to reduce swelling and combat infection. In some instances, treatment may involve interventions to increase the production or reduce the leakage of the aqueous humour to restore normal pressure levels.

It is important for anyone experiencing symptoms of hypotony to seek medical attention promptly, as untreated hypotony can result in permanent damage to vision. Regular eye examinations and monitoring are essential for those at risk of developing hypotony or those recovering from eye surgery. By managing the condition effectively, patients can maintain a better quality of vision and eye health.

What is the Eye Condition Hypotony?

Hypotony is a problem with the eye. It means the pressure inside the eye is too low. This pressure is called intraocular pressure (IOP). The right pressure helps the eye keep its shape and work well. If the pressure is too low, it can cause problems and make it hard to see.

In healthy eyes, the IOP is usually between 10 and 21 mmHg (millimetres of mercury). If the IOP goes below 6 mmHg, it is called hypotony. This can happen for different reasons, like too much fluid leaking out of the eye, not enough fluid being made, or too much fluid draining away. This can be because of surgery or injury to the eye.

One common reason for hypotony is problems after eye surgery, especially after surgery for glaucoma. Other causes can be injury, swelling, or problems after other types of eye surgeries. Issues like retinal detachment or some eye infections can also cause hypotony.

Symptoms of hypotony can be different. They might include blurred vision, feeling discomfort in the eye, or seeing the eye change shape. Sometimes, very low IOP can cause problems like swelling in the retina, or changes in the retina that can make things look wavy or blurry.

To find out if someone has hypotony, an eye doctor will check the eye carefully. They might use a tool to measure the pressure in the eye. They might also do tests to look at the inside of the eye.

Treating hypotony means fixing the reason for the low pressure. If it is because of surgery, more surgery might be needed. If it is because of injury or swelling, doctors might give medicine to help. They might use medicine to stop swelling or fight infections. Sometimes, treatment is needed to get the pressure back to normal.

Anyone with signs of hypotony should see a doctor quickly. If hypotony is not treated, it can cause lasting vision problems. Regular eye checks are important, especially for people who have had eye surgery. By taking care of the condition, people can keep their vision and eye health better.
