What are the Symptoms of Hypotony?

Hypotony, also known as hypotony of the eye, is a condition characterised by abnormally low intraocular pressure. It is essential to note that the symptoms of hypotony can vary depending on the severity of the condition and the underlying cause. Recognising these symptoms is crucial as it can indicate a significant underlying issue potentially impacting vision.

One of the primary symptoms of hypotony is visual blurring. This occurs because the eye struggles to maintain its usual shape due to the reduced pressure, leading to changes in the way light rays are focused on the retina. Such visual disturbances can be intermittent or constant, becoming more noticeable when performing tasks that require sharp vision.

Other symptoms that may accompany hypotony include vision distortion and double vision. These occur due to changes in the eye’s physical shape and an irregular corneal surface. Patients might also experience a decrease in visual acuity, making everyday activities, like reading or driving, increasingly challenging.

Some individuals with hypotony report a sensation of pressure or fullness in the eyes. This feeling might not necessarily be painful but can be uncomfortable and disconcerting. It's often mistaken for eye strain or fatigue but persists even with rest.

Pain in the eye or around the orbital region, although not universally experienced, can sometimes accompany hypotony, especially if the low intraocular pressure leads to complications like choroidal detachment. This kind of pain does tend to be more severe and can significantly impact daily life.

For some, hypotony can lead to red eyes or increased eye watering. These signs can be due in part to the eye’s compensatory mechanisms in response to its impaired function or secondary to inflammation or infection resulting from the underlying causes of hypotony.

Less commonly, hypotony might be associated with a visible reduction in the size of the eye or changes in its contour, which can be observed either by a healthcare professional or, in some cases, the individual themselves. This is often a sign of chronic low intraocular pressure and can lead to more severe complications.

Lastly, a notable symptom of hypotony is an increased sensitivity to light, known as photophobia. This symptom can arise when the reduced intraocular pressure affects how the eye reacts to light levels.

If you suspect you may be experiencing symptoms of hypotony, it is crucial to seek advice from an eye care professional. Early diagnosis and management can help prevent potential complications associated with this condition.
