What Causes Glaucoma?

Glaucoma can be described as a medical condition that damages the optic nerve, crucial for good eyesight. In many cases, the damage is typically due to high pressure in the individual’s eye. The degree of pressure may erode the individual’s optic tissue, which results in vision loss or blindness in some cases.

Glaucoma is one of the significant causes of blindness for individuals above the age of 60. Please note that this condition can occur in people of different ages, but it’s prominent in older adults. Most types of glaucoma are not linked to any warning signs. Hence, it’s crucial to discover the possible causes of this medical condition.

There are no specific known causes for the cause of high pressure in the eye. However, doctors believe a few potential factors play a crucial role in the cause of glaucoma. Here are possible causes:

Elevated Blood Pressure

There’s a link between high intraocular pressure and high blood pressure, diabetes has impacts on the eyes when blood glucose is too high. In the short term, there is no vision loss from high blood glucose. But people may have a blurry vision loss for a couple of days or weeks when they are changing their diabetes medication. This type of blurred vision is temporary and disappears when your blood sugar level approaches normal. And if your blood glucose stays high over time, it may damage the tiny blood vessels in the back of the eyes. It needs to note that ocular hypertension describes a condition where the human eyes’ pressure is too high, which may damage the optic nerve.

Besides, high blood pressure doesn’t only pose a risk to the human eye, causing glaucoma. It may also damage the light-sensitive tissues at the back of the human eye (retina), which causes bleeding in the eye. This condition is known as retinopathy, and it may cause blurred vision or total loss of eyesight. [1]
