Description
Humphrey FDT – for Efficient Visual
Field Loss Detection
Clinically validated
Multiple studies have shown that the Humphrey FDT detects visual field loss due to a variety of ocular diseases, including glaucoma. Thus FDT is ideal for clinics desiring to identify patients in need of ophthalmological referral.
• FDT is clinically validated in more than 170 peer-reviewed publications.
Easy to Operate and Interpret
The FDT is optimized for use in non-ophthalmological settings and may be operated by healthcare workers having little or no specialty training in ophthalmology.
• Simplified three touch operation.
• Patients may be tested using their own glasses. • Short test: ~ 40 seconds per eye.
• Small footprint.
• Simplified interpretation of results.
Proven Performance on Virtually All
Patients
Studies have found that virtually all patients can perform this fast and simple test with reliable results:
• Beijing Eye Study: 98% patient success.
• Tajimi Population Screening Study: 98.7% patient success.
