Glaucoma’s Effects on Vision

Glaucoma is an eye disease. It belongs to the illness that can cause blindness. It affects the optic nerve and leads to the devastating damage of vision. The eyesight becomes worse eventually. It happens because of the loss of communication between the eyes and the brain. Left untreated the pressure can impair vision by causing serious damage to the optic nerve.Glaucoma results in peripheral vision loss and this is why it often referred as “the sneak thief of sight.”

The vision that lies with the glaucoma or affects by the glaucoma disease is referred by the glaucoma vision.

It happens because of the fluid liquid. It is clear that begins to build up and thus creating pressure and discomfort to the vision. The clear fluids in the eye don’t become empty by removing all the liquid from it as they should. Accordingly this is the reason that raises the pressure levels and limits vision in the sense of glaucoma vision. If a person loses his vision to this disease, it can’t be replaced other than further damage can be done.

Types of glaucoma

Basically there are two main types of glaucoma and those are:

  1. 1.     Open-angle glaucoma: This is the most common type of glaucoma. It is also called by wide-angle glaucoma. Here the structure of the eye appears normal. But the fluid liquid in the eye does not flow properly through the drain of the eye.
  2. 2.     Angle-closure glaucoma: This type of glaucoma is rare but can cause a sudden blindness in the eye. It is also called acute or chronic angle-closure or narrow-angle glaucoma. Here the drainage is poor because the angle between the colored part round the pupil of the eye which is called iris and the cornea where the drainage channel for the eye is located is too narrow. The pupil opens too wide that narrowing the angle and blocking the flow of the fluid through that channel.

Apart from these two there are a variety of different types of glaucoma. Some common forms are mentioned below:

  • Normal tension glaucoma
  • Pigmentary glaucoma
  • Exfoliation Syndrome
  • Trauma related glaucoma
  • Childhood glaucoma




Possible Signs of Glaucoma

There are various types of glaucoma that can occur and progress without giving any symptoms or signs. Open-angle glaucoma is the most common one. Its symptoms are slow to develop. For this type of glaucoma progresses you may notice by your side that your peripheral vision or tunnel vision is losing. Your vision is failing and causing you to miss the aim out of the side and corner of the eye.


If you are experiencing the symptoms like-

  • Blurred vision
  • Halos around bright lights
  • Nausea
  • Headaches etc.

Then you can have angle-closure glaucoma and you should have immediate treatment.

Risk Factors

There are some risk factors associated with the glaucoma such as-

  • Family History
  • Age
  • Medical condition
  • Eye injury etc.

Above all people of age 60 and older have an increased risk of having glaucoma as they suffer from diabetes and high blood pressure.


There is no actual cure for glaucoma vision. Damage cannot be move backwards. But the medication and techniques as laser surgery can help to prevent glaucoma vision loss. Very quick detection and treatment are obligatory to slowdown the progression of impacts caused by glaucoma.

Glaucoma & Cataracts

Glaucoma and cataracts are the two conditions of the eye. Both conditions of the eye can effect vision and cause blindness.

A norma eye lens is clear. Cataracts cloud the lens and cause it to apear foggy. It may lead to partial vision loss. With a few side effects it requires a relatively fast surgery.

The difference between these two is if treated promptly cataracts are reversible through surgery while glaucoma is irreversible.
