Humphrey FDT Visual Field
The Humphrey® FDT Perimeter uses Frequency Doubling Technology to provide a clinically verified, fast, and accurate means of detecting early visual field loss. The FDT is the ideal visual field screening device because it conducts supra-threshold testing in only 40 seconds per eye. We screen every patient with the FDT Perimeter and were the first practice in central Pennsylvania to incorporate this technology.
Optos Retinal Map
The Optomap exam is fast, painless, and comfortable. Nothing touches your eye at any time. It is suitable for the whole family. To have the exam, you simply look into the device one eye at a time (like looking through a keyhole) and you will see a comfortable flash of light to let you know the image of your retina has been taken.
Under normal circumstances, dilation drops might not be necessary, but your doctor will decide if your pupils need to be dilated depending on your conditions. The capture takes less than a second. Images are available immediately for review. You can see your own retina. You see exactly what your eye care practitioner sees – including a 3-D animation. We incorporated the Optomap into our practice in 2006. The Optomap may be covered by your insurance.

Barrett Vision Center LLC now provides an even more thorough examination and diagnosis of your retina than ever before with the Zeiss Cirrus™ high-definition OCT. This cutting-edge diagnostic system allows our doctors to get a complete cross-sectional or 3-dimensional view of your retina.
