What the Exam Shows
The exam from the GDx prints a color coded "thickness map" of the nerve fiber layer at the back of your eye. This information can assist the doctor to get objective values on the early changes which may help to determine if you have glaucoma. It also helps to follow patients who have already been diagnosed with glaucoma.
The GDx can be used to track the progression of eye disease and it can help to determine if you have glaucoma. The GDx can be used on periodic times during the year to see if there are any changes which have not been seen on the visual field or through the dilated examination when evaluating the optic nerve head. Patients who are at risk for glaucoma should have a GDx done as a baseline in conjunction with a thorough eye examination by a physician. For a definition of at risk patients, please click here. Insurance The GDx is covered by Medicare in the state of Illinois and by most insurance companies. Please ask for payment options if your insurance doesn’t cover the exam, or if you have no insurance.

During the exam Dr. Mildred M.G. Olivier will use a variety of technology to give you as complete of a glaucoma evaluation and consultation as possible. New technologies such as the GDx allow her to determine if you have glaucoma prior to you experiencing any vision loss. It also gives her a baseline by which to follow the progression of glaucoma for individuals already diagnosed. Other reliable technologies such as the Humphrey visual field machine allow Dr. Olivier to determine and measure vision which has already been lost. She can also track progression of a disease with this technology. The perimetry (visual field) examination is the standard used for detecting and evaluating glaucoma.
