In the News: All About Glaucoma – Part I

During the month of March, National Glaucoma Week is celebrated to raise awareness for this condition that affects nearly 3 million people every year. Here we will discuss all things glaucoma.

What is glaucoma?

Glaucoma is a group of eye conditions that damage the optic nerve, which is crucial for transmitting visual information from the eye to the brain. 

What are the symptoms of glaucoma?

While glaucoma starts out typically asymptomatic, the gradual progression of the symptoms can include:

• Loss of peripheral or side vision
• Seeing halos around lights and glare in bright light
• Redness in the eye
• Eye pain
• Eye that looks hazy (particularly in infants)
• Narrow or tunnel vision
• Vision Loss 

What causes glaucoma?

 The fluid inside the eye nourishes the lens and the cells of the cornea and maintains a pressure, which allows the cornea to maintain its convex shape that is necessary for good vision. The pressure inside the eye or the intraocular pressure is maintained at a constant due to drainage of excess fluid out of the eye.

Increased pressure inside the eye due to the obstructed flow of the fluid may lead to glaucoma. 

Other causes may include family history, association with other diseases like hypertension and diabetes, burn or chemical injury to the eye, or trauma to the eye.
