Glaucoma is an eye condition that affects millions of people around the world and can lead to permanent vision loss if left untreated. It is caused by a buildup of pressure in the eye, which damages the optic nerve, the nerve responsible for carrying signals from the eye to the brain. Glaucoma is the leading cause of blindness in the United States and is one of the most common causes of vision loss worldwide. 

The most common type of glaucoma is primary open-angle glaucoma, which usually develops slowly without any pain or symptoms. There is no cure for glaucoma, but it can be managed with medications, laser surgery, or traditional surgery.

Understanding the causes of glaucoma, its symptoms, and treatment options is essential for anyone at risk of developing the condition.

What Causes Glaucoma?

The most common cause of glaucoma is an increase in pressure in the eye, called intraocular pressure (IOP). This increased pressure can cause damage to the optic nerve, which carries visual information from the eye to the brain. Other factors that can contribute to glaucoma include genetic factors, age, underlying health conditions (such as diabetes), and certain medications. 

What Are the Symptoms of Glaucoma?

The early stages of glaucoma often have no noticeable symptoms. As the condition progresses, you may experience any of the following:

  • Blurred vision
  • Halos around lights
  • Reduced peripheral vision
  • Eye pain
  • Redness of the eye
  • Headaches

If you experience any of these symptoms, it is important to see an eye doctor for an evaluation.

How Is Glaucoma Treated?

The goal of glaucoma treatment is to reduce IOP in the eye and prevent further damage to the optic nerve. The most common treatment options are medications, laser surgery, and traditional surgery. 

  • Medications: Medications, such as eye drops and pills, are the most common form of treatment for glaucoma. They work by reducing the production of fluid in the eye or increasing the outflow of fluid from the eye, which can help reduce IOP.
  • Laser Surgery: Laser surgery is a type of surgery that uses a laser to target specific areas of the eye to reduce IOP. It is a non-invasive procedure that can reduce IOP without damaging the eye.
  • Traditional Surgery: Traditional surgery is a more invasive option for treating glaucoma. It involves making a small incision in the eye to create a drain for the fluid, which can help reduce IOP.
