Special Testing



Zeiss Retinal Camera

Zeiss Retinal Imaging is provided by a camera that takes pictures of the inside of a patient's eye (or retina).  These pictures are then reviewed with patients to discuss any current or potential conditions that may be present.  The images are then saved and can be easily referenced in the future if any changes occur.  The pictures are especially helpful to follow patients with diseases such as diabetes mellitus, high blood pressure, macular degeneration, and glaucoma, however, all patients are encouraged to have periodic images. 


GDx Nerve Fiber Analyzer 

The GDx is a state-of-the-art instrument that has the ability to measure the thickness of the retinal tissue within the eye.  The increase in pressure within the eye associated with glaucoma, damages the retinal nerve fiber layers by compressing them.  The analysis of these layers has become vital in the diagnosis and treatment of glaucoma.  Thanks to this new instrument, we have another piece of information to help diagnose and treat this difficult disease.


Humphrey Visual Field Analyzer

The Humphrey automated perimeter is a diagnostic tool used to examine a patient's peripheral vision.  This helps to assess any potential blind spots that may indicate abnormalities.  Many eye and brain disorders can cause peripheral vision loss.  For example, glaucoma, strokes or brain tumors can cause very specific visual field defects that are helpful in diagnosis of these conditions.  Visual field testing is also used for patients who take certain high-risk medications.
