Neovascular Glaucoma Information:

If you experience a sudden loss of vision and when you feel some pain or discomfort with a red eye, then you should be alarmed as this could be neovascular glaucoma, and unusual type of glaucoma that medical practitioners find difficult to treat.

What Causes Neovascular Glaucoma?

The disorder known as neovascular glaucoma is categorized as a closed-angle glaucoma as the tiny drain where the aqueous humor or the fluid that nourishes the eyes is blocked, closed, or exits the eye. This condition is brought about by the abnormal growth of new blood vessels (in a process called neovascularization), that are not usually found in this location of the eye’”hence, the name neovascular glaucoma.

Why Do New Blood Vessels Grow in the Eyes?

There are instances when the eyes’ blood vessels are partially or entirely blocked causing the surrounding tissues in the eyes to lack the needed oxygen and nourishment. When this happens, these surrounding structures of the eyes produce certain chemicals that further cause the growth of new blood vessels in a process termed as neovascularization. This occurs more often at the retina or at the back of the eye. In a period of two to three months, the same chemicals can seep and leak to the front of the eyes and cause the same process to develop over the colored portion of the eye or the iris and the trabecular meshwork.

The growth of these new blood vessels pull the iris against the meshwork, adhere to it, and permanently block the drainage path.

Who Are at Risk for Developing Neovascular Glaucoma?

Obviously, individuals experiencing poor or inadequate blood flow to their eyes are more likely to develop the condition. The eyes are nourished and provided oxygen by the body’s blood. The blood flow is also responsible for removing waste from the eyes. In the same note, the aqueous humor or the fluid responsible for the nourishment of the eyes’ inner parts is only properly developed when an adequate blood supply is present.

More particularly at risk with neovascular glaucoma are those individuals who are suffering from diabetes, especially when the condition has been experienced for more than ten years already. This is because diabetes reduces the blood flow in many parts of the body including the eyes. Also included in the list of more at risk with this type of glaucoma are those individuals who have high blood pressure. Hypertension makes one individual more susceptible to having blood vessels collapse. And finally, those elderly people or the aged are also most likely to suffer from neovascular glaucoma with their impaired blood flow to the eye.
