Frequency Doubling Technology

“Frequency Doubling Technology” is referred to as an FDT Visual Field. The FDT is a state-of-the-art instrument that has proven highly useful in the early detection of glaucoma and other eye disorders.  Regular testing with the FDT is a safe, fast, and reliable way to detect eye disease.

Why is visual field testing important?

The visual field test provides a map of the field of vision.  The map shows precisely where different intensities of light are seen or not seen in the field of vision.  This test can help show whether or not blind spots are developing as a result of glaucoma or other eye disorders.
