Glaucoma is the second leading cause of blindness. Sometimes called the silent thief of sight, glaucoma can damage your vision so gradually you don't notice any loss of vision until the disease is at an advanced stage. The most common type of glaucoma, primary open-angle glaucoma, has no noticeable signs or symptoms except gradual vision loss. Early diagnosis and treatment can minimize or prevent optic nerve damage and limit glaucoma-related vision loss.
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.
