What is the GDx test?
GDx stands for Glaucoma Diagnosis. It is a new computerized test that measures the thickness of the eye nerve tissue. It is similar to taking a picture of the inside of the eye. It is painless, quick and does not require that your eyes be dilated. It is used for diagnosis of early glaucoma; for follow up of glaucoma treatment and in early detection of glaucoma in relatives of glaucoma patients.
