Frequency Doubling Perimetry Technology or Frequency Doubling Technology (FDT) Perimetry is a procedure used to detect visual field loss caused by Glaucoma and other Ophthalmological diseases. An enhanced version of FDT Perimetry has been released called the Humphrey visual field test or the Humphrey Matrix. FDT Perimetry was designed to identify peripheral vision and sensitivity loss produced by various visual disorders, including Neuro-ophthalmological diseases like Thyroid Eye Disease, Ischemic Optic Neuropathy and Blepharospasm.
Features of Humphrey FDT’s and other FDT Perimeters often include quick test time; often under a minute per eye, small footprint for a fit in every practice and ease of use as well as full threshold test results in less than five minutes. This allows a practice an efficient and rapid method of testing patients for visual disorders while maintaining patient comfort and convenience.
