Glaucoma

Glaucoma - aboutGlaucoma is an eye disease in which the passages that allow fluid in the eye to drain become blocked or clogged.  This results in the amount of fluid in the eye building up and causing increased pressure inside the eye.  This increased pressure damages the optic nerve which connects the eye to the brain.  The optic nerve is the main carrier of vision information to the brain.  Damage to it results in less information sent to the brain and loss of vision.

Glaucoma is one of the leading causes of blindness in the U.S.  If detected at an early stage and treated promptly, glaucoma can usually be controlled with little or no further vision loss.  That’s why regular eye examinations are so important.  People of all ages can develop glaucoma, but it most frequently occurs in people:

  • who are over age 40
  • who have a family history of glaucoma
  • who are very nearsighted
  • who are diabetic
  • who are of African American descent

Of the different types of glaucoma, primary open angle glaucoma often develops gradually and painlessly, without warning signs or symptoms.  This type of glaucoma is more common among blacks than whites.

Another type, acute angle-closure glaucoma may be accompanied by:

  • a loss of side vision
  • appearance of colored rings
  • blurred vision
  • around lights
  • pain or redness in the eyes

Regular eye examinations are an important means of detecting glaucoma in its early states, and will include:

  • Tonometry – a simple and painless measurement of the pressure in the eye.
  • Ophthalmoscopy – an examination of the back of the eye to observe the health of the optic nerve.
  • Visual field test – a check for the development of abnormal blind spots.

Glaucoma can usually be treated effectively by using eye drops or other medicines.  In some cases surgery may be necessary.  Unfortunately, any loss of vision from glaucoma cannot usually be restored. But, early detection, prompt treatment and regular monitoring can enable you to continue living in much the same way as you have always lived.
