The Humphrey Matrix FDT 710 - Double Frequency Technology
The Zeiss Humphrey Matrix FDT 710 perimeter represents a cutting-edge advancement in diagnostic technology, developed and distributed by Carl Zeiss Meditec, a renowned leader in ophthalmic diagnostic equipment. Carl Zeiss Meditec is also recognized for its Humphrey Field Analyzer, which stands as the gold standard in visual field testing and is widely used by eye care providers worldwide.
As part of Carl Zeiss Meditec's comprehensive suite of diagnostic solutions for eye diseases, the Humphrey FDT 710 plays a pivotal role in identifying patients in need of ophthalmologic referral. Numerous studies, totaling over 170 peer-reviewed publications, have clinically validated the effectiveness of the Humphrey FDT in detecting visual field loss associated with various ocular conditions, including glaucoma.
The Humphrey FDT's performance has been proven to be reliable across a broad spectrum of patients, with high success rates documented in studies such as the Beijing Eye Study and the Tajimi Population Screening Study. This versatility enables its use in a range of settings, including general hospitals, polyclinics, community clinics, industrial health check clinics, and even optical shops.
One of the key advantages of the Humphrey FDT is its ease of operation and interpretation. Designed with simplified three-touch operation, patients can be tested quickly and efficiently, with a short testing time of approximately 40 seconds per eye. Moreover, patients can undergo testing using their own glasses, further enhancing convenience and comfort.
The ergonomic design of the Humphrey FDT ensures patient comfort, with features such as a comfortable headrest, large and easily visible test stimuli, and an ergonomic response button. These elements contribute to a positive testing experience for patients, minimizing discomfort and facilitating accurate responses.
The Zeiss Humphrey Matrix FDT 710 perimeter offers a comprehensive set of test specifications to ensure accurate and reliable visual field testing. With a maximum temporal range of 30 degrees, it provides ample coverage for assessing the patient's field of vision. The stimulus duration of 300 ms ensures optimal presentation of stimuli to elicit accurate responses from the patient.
Operating at a visual field testing distance of infinity, the Humphrey Matrix FDT 710 accommodates varying patient needs and facilitates testing in diverse clinical settings. The background illumination of 100 cd/m² ensures consistent lighting conditions during testing, minimizing potential confounding factors.
The device comes equipped with two threshold test libraries, N-30 and C-20, offering flexibility in tailoring the testing protocol to the specific needs of each patient. Additionally, the screening test library includes both C-20 and N-30 modes, allowing for efficient screening assessments.
For enhanced accuracy, the screening test modes are age-corrected, accounting for variations in visual field function associated with age. This feature ensures that test results are interpreted within the appropriate context, further enhancing the clinical utility of the Humphrey Matrix FDT 710 perimeter.
In summary, the Zeiss Humphrey Matrix FDT 710 perimeter represents a powerful tool in the early detection of visual field anomalies, offering unparalleled ease of use, reliability, and clinical performance. Its integration into clinical practice provides valuable insights into the effects of eye diseases on visual function, ultimately aiding in the delivery of optimal patient care.
