January is National Glaucoma Awareness Month

Glaucoma is a group of eye diseases that gradually steal sight without warning. Although the most common forms of glaucoma primarily affect the middle-aged and the elderly, glaucoma can affect people of all ages. Vision loss is caused by damage to the optic nerve. The optic nerve is like an electric cable with millions of wires which carry images from the eye to the brain. There is no cure for glaucoma. However, medication or surgery can slow or prevent further vision loss.

Traditionally, glaucoma has been tested by measuring the pressure in the eye, visual field testing and careful evaluation of the optic nerve. The GDx uses a laser to determine the thickness of the nerve fiber layer. This allows us to detect early signs of the disease, typically 5-7 years prior to vision loss. This technology is key in early detection and prevention, specifically to those with a family history of glaucoma.

“Glaucoma is a serious disease and the second leading cause of blindness in the world,” stated Dr. Timothy J. Leach from the uptown St. Charles Vision office. “In fact, over 4 million Americans have glaucoma but only half of those know they have it. This is why we always encourage annual eye exams with GDx glaucoma testing. Early detection is so important in order to prevent vision loss.”

The doctors of St. Charles Vision highly suggest that an annual eye exam be conducted in order to not only check routine issues, but also to test and examine for glaucoma. Early detection is very important. Some of the St. Charles Vision locations offer an advanced GDx test that can detect early signs of the disease.
