Diagnostic Technology

At VisionQuest Eyecare, we use the latest technology to help diagnose and treat our patients. Below are some of the technological advancements we use at our office.


A thorough screening of the retina is critical to verify that your eyes are healthy. The Optomap is a non-Xray, painless, fast digital retinal screening that takes a panoramic picture of your retina. The images taken by the Optomap captures 80% of the retina, while other methods typically only show around 15%.

Optical Coherence Tomography (OCT)

The OCT is a non-invasive imaging test that uses a harmless laser to take cross-section pictures of your retina. These measurements help with diagnosis and provide treatment guidance for glaucoma and retinal diseases, such as age-related macular degeneration and diabetic eye disease.



The Adaptdx helps detect early signs of age-related macular degeneration by testing the eye’s ability to adapt in the dark. Impaired dark adaptation is an early sign of age-related macular degeneration. The AdaptDx is the first instrument designed to provide practical dark adaptation testing in a doctor’s office.


TearLab Osmolarity System

The TearLab Osmolarity System measures the osmolarity (the concentration of solutes in the tear film) of human tears to aid in the diagnosis of dry eye disease in patients suspected of having dry eye disease.



A VEP test measures the electrical activity in the vision system. When light from an image enters your eye, it is converted into electrical energy at the retina and travels through the optic nerve to the brain which processes vision. The VEP test measures the strength of the signal reaching your visual cortex and how fast it gets there.

An ERG test is used to detect abnormal function of the retina. The light-sensitive cells of the eye, rods and cones in the retina, are examined. When light from an image enters the eye, it is converted into electrical energy by specialized cells in the retina. These cells send electrical impulses through the optic nerve to the brain where the image is processed. The ERG test records how well the cells of the retina are conveying electrical impulses within the eye.
