The Zeiss GDx is the Gold Standard in early detection of glaucoma. The instrument measures the thickness of the retinal nerve fiber layer and compares your results to other patients of your age. Numerous studies have demonstrated that the earliest sign of glaucoma is a thinning of the retinal nerve fiber layer.
Glaucoma is an eye disease commonly referred to as the thief of sight because it often attacks without warnings or symptoms. Glaucoma refers to a family of eye diseases where fluid in the eye builds up enough pressure to damage the nerve fibers in the retina resulting in irreversible loss of vision. In some cases this can lead to total blindness if undetected and untreated. There is no cure for glaucoma and no way to reverse the damage inflicted by this disease. However, if detected and treated in its early stages blindness can almost always be prevented.
Recent developments in technology, such as GDx VCC screening, allow doctors to capture and examine high-resolution images of a patient’s retina enabling them to detect nerve fiber damage before pressure builds up and symptoms appear. If caught in its early stages, treatment can often prevent vision loss
The Zeiss GDx VCC (Glaucoma Detection with Variable Corneal Compensation) retinal scanner a optometric diagnostic instrument that performs a non-obtrusive retinal scan that measures the thickness of the retinal nerve fiber layer (RNFL) without dilation. A change in the thickness of this nerve layer is an early risk factor for glaucoma.
