What is Glaucoma?

79250257.jpgGlaucoma is a leading cause of blindness in the United States and chances of suffering glaucoma increases with age. Loss of sight from glaucoma may be preventable when treated early. Glaucoma is a common eye disorder that is, in fact, not one but an entire group of disorders with a common label. It is a disorder that damages the optic nerve, which serves to send the images from the eye to the brain.

It was once believed that glaucoma was caused by high fluid pressure inside the eye (called intraocular pressure). Experts now know that, while high intraocular pressure is a risk factor for glaucoma, it is not the only cause.

The early stages of glaucoma are undetectable and experts estimate that only half of the people who currently have glaucoma even realize that they are affected. While there is no cure for glaucoma, many medications and procedures exist that can help to slow the disease. While there is no cure for glaucoma, many medications and procedures exist that can help to slow the disease. However, like so many eye-related disorders, early diagnosis is essential. Because the early stages of glaucoma have no noticeable symptoms, regular eye exams are recommended for everyone, even those who have no eye-related symptoms or problems.

What Causes Glaucoma?

When clear liquid (aqueous humor) flows in and out of the eye at an uneven rate due to fluid pressure within the inner eye, the optic nerve is damaged. Higher intraocular pressures lead to a higher risk of glaucoma. Higher pressures lead to a higher likelihood of developing glaucoma at a faster rate, but, some patients with elevated pressures will not develop glaucoma and some patients with normal pressures will develop glaucoma.

Symptoms of Glaucoma

  • Blurry vision
  • Headaches
  • Seeing rainbows
  • Seeing spotty light
  • Severe eye pain
  • Nausea and vomiting

Diagnosing Glaucoma

Regular eye exams are the best way to detect glaucoma. Your doctor will measure your intraocular pressure, evaluate any nerve damage, check the drainage angle of your eye and test your vision. Photographs of your optic nerves may be taken in order to view the appearance of your optic nerves.

Treating Glaucoma

  • Medication such as pressure lowering agents drops
  • Laser procedures
  • Incisional surgery
  • Shunts / Implants

Early detection of glaucoma is important so that it can be treated, which may be able to slow or halt the progression of the disease. Once the vision is lost, it cannot be restored.
