Carl Zeiss Meditec, one of the world’s leading medical technology companies, offers integrated solutions for treating the four main eye diseases: vision defects (refraction), cataracts, glaucoma and retinal disorders. Diagnostic products range from slit lamps and fundus cameras to standard-setting diagnostic systems such as the Humphrey Field Analyzer, the Cirrus™ HD-OCT and the IOLMaster.® Carl Zeiss Meditec also produces surgical microscopes and innovative treatment systems for refractive laser surgery.
FDT can help your staff detect vision loss in
Multiple studies1-15 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.
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.
The Humphrey FDT can detect visual field loss
associated with a variety of ocular diseases
Ocular diseases without specialized training
Use the FDT Anywhere:
- General hospitals
- Community clinics
- Industrial health check clinics
- Optical shops
Patients with a positive FDT result can be referred for specialized ophthalmic examination. Interpretation criteria may be adjusted for local conditions.
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
- Comfortable headrest
- Large, easily seen test stimuli
- Ergonomic response button
- Short testing time
The FDT is a small, automated peripheral vision testing device. The patient simply presses a response button whenever he/she sees a test stimulus. These simple perating requirements, coupled with the instrument’s well-documented clinical performance, make it a natural choice to detect the effects of eye diseases on visual function.
FDT is ideal for screening
- Highly sensitive in detecting visual field loss associated with a range of eye diseases
- Can be placed almost anywhere, including non-ophthalmic clinical settings
- Technician operated, with minimal training
- Fast and easy testing for patients in 40 seconds per eye
- Simple to understand test
Shaded locations in the FDT printout indicate areas of visual field sensitivity that are outside normal limits.
• The results illustrated above are consistent with a diagnosis of glaucoma. The darkest symbols indicate areas of the patient’s peripheral vision that were lower than that found in 99.5% of normal subjects.
The C-20-1 test emphasizes high specificity and is therefore best designed for general screening of large populations. The C-20-5 test emphasizes high sensitivity to optimize detection of early, subtle pathologic sensitivity loss, and is best designed for screening ophthalmic patients with risk factors or symptoms associated with eye diseases.
