After the optic nerve gets damaged, the eye is unable to send the image information to the brain. So finally, it causes a permanent vision loss. According to a report, Glaucoma is the second largest eye blindness disease; it affected more than 60.5 million people around the world in the year 2010 and it may increase 80 million by the year of 2020.

Types of Glaucoma:

  • Closed-angle glaucoma: This type of glaucoma is common in several people. Basically, this type of glaucoma creates heavy pressure and pain suddenly and also makes the short time vision loss. In this type, the patients can easily skip by following the regular doctor advice and medical treatments.
  • Open-angle glaucoma: This type of glaucoma problem is not easily understood or diagnosed by the people. This disease grows slowly and not shows any symptoms. But it will make the vision loss permanent. Patients are not able to regain the vision by using the medical treatment, after the nerve damaged in the eyes.

What are the symptoms of glaucoma?

Glaucoma is a complicated eye health condition that damage eye’s optic nerve leads to vision loss.

There are two major kind of glaucoma one is most common type “open-angle glaucoma” also calls it “wide-angle glaucoma” and other is less common type “Angle-closure glaucoma” also called as “chronic angle-closure or narrow-angle glaucoma”.

The symptoms and signs of open-angle glaucoma and angle-closure glaucoma are slightly different.

Symptoms of Open-Angle Glaucoma

Most people don’t have any early symptoms or warning signs. It is a silent killer for eye and develops slowly without any noticeable hint. Most of the folk feel fine and don’t recognize a change in their vision in initial level because the early loss of vision is a peripheral vision and the sharpness of vision is sustained until late in the disease. That’s why open-angle glaucoma is called as “sneak thief of vision”.

  • Central or peripheral vision is slowly but surely lost mostly affects in both eyes.
  • In complex stage person experience tunnel vision

Symptoms of Angle-Closure Glaucoma

Symptoms of acute angle-closure glaucoma are clear and visible. Some people have early symptoms can include halos, eye pain, blurred vision, mild headaches etc. If anyone suffers from these kinds of symptoms should be consulted immediately with their ophthalmologist.
