How Untreated Medical Conditions Lead to Loss of Eyesight

The eye is a complex, fascinating organ. Sight requires multiple parts to flawlessly work in conjunction with one another: The lens, the retina, the iris, and optic nerves. These individual aspects all function together to take in light, process it, and send it to the brain to be interpreted as vision.

However, if any of these parts fail, it can lead to diminished vision and even complete loss of eyesight. This can happen for a number of reasons, but some of the most surprising are the seemingly unrelated conditions that, if left untreated, can significantly and permanently damage your eyes.


High Blood Pressure

Believe it or not, high blood pressure can cause several problems with the essential functions of your eyes.

Your eyes are filled with tiny blood vessels. High blood pressure, if ignored, can eventually damage these blood vessels, effectively cutting off the blood supply to your eye. Over time, the lack of flow to the retina can lead to blurred vision and blindness. This condition is known as retinopathy.

Blood pressure can also cause a build-up of liquid under the retina, leading to distortion and potential scarring that can impair vision.

Furthermore, there is a risk of temporary or permanent damage to the optic nerves due to blocked flow.



Glaucoma is an accumulation of fluid that can cause pressure to build up in the eye. It is a progressive condition that can eventually damage the retina and optic nerve, leading to a loss of peripheral vision.

Unfortunately, glaucoma cannot be reversed and often goes undetected. However, there are proactive treatments capable of slowing its progress such as eye drops and surgical procedures.



Diabetes, a serious affliction in its own right, is also responsible for a great number of cases in which vision is significantly impaired or lost entirely.

Diabetic retinopathy involves damage to the blood vessels in the eyes, causing them to leak or bleed. It is the most common reason for vision loss among diabetics, and a leading cause among all working-age adults.
