Zeiss GDx VCC Retinal Scanner

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 Optomap® and 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.

Adler Eye Associates highly recommends Optomap® and GDx VCC screening exams as part of your annual eye exam for the early detection of retinal problems such as macular degeneration, glaucoma, retinal holes or detachments and diabetic retinopathy (all which can lead to partial loss of vision or blindness if undetected and untreated).

Optomap® and GDx VCC screening exams are optional procedures and are not covered by insurance providers. For more information about our Optomap® and GDx VCC screening including pricing information, please read our Optomap® and GDx VCC screening form.

We also encourage you to visit the Optos Optomap® web site. This site is intended to further educate the patient on Optomap® screening including a nice video featured on the syndicated daytime talk show "The Doctors".
