What Is the Zeiss Visual Field Test?

Diagnostic devices are a critical factor in the management of all diseases. Early diagnosis is essential in maintaining good vision regarding eye conditions. Some eye conditions do not present symptoms until they are advanced to irreversible. Proper diagnosis is, therefore, critical in preserving vision.


One of the primary eye conditions that require early diagnosis is glaucoma. Glaucoma is a series of eye conditions that affect ocular pressure. They usually develop slowly, except for one type of glaucoma. Their gradual development makes it difficult for anyone to notice them. However, eye doctors can identify the condition with proper diagnostic tools like the Zeiss visual test.


The Zeiss visual field test is a diagnostic procedure that eye doctors use to test your visual field of vision. It allows them to identify anomalies in your vision that are hard to notice through other methods. If you have an eye condition like glaucoma, your visual field is most likely affected.


The changes in the visual field are usually so small that without advanced technology, we would not be able to tell. Zeiss technology helps eye doctors identify and map these changes accurately. The test results give the eye doctor an idea of what eye condition causes them.


 

How Do Eye Doctors Perform the Zeiss Visual Field Test?



Eye doctors perform the Zeiss visual field test using different Zeiss technologies. The devices help them map your visual field accurately. The devices use a combination of imaging technologies to acquire data. One of the most trusted devices is the Zeiss Humphrey Matrix 715 Visual Field Analyzer.


 

Why Is Humphrey Matrix 715 Visual Field Analyzer So Efficient?



As mentioned above, the Zeiss device utilizes several technologies simultaneously to collect data. It makes the work easier for eye doctors and provides more efficiency. The device is a powerful perimeter that uses the Welch Allyn Frequency Doubling Technology. 


It is a notable breakthrough in visual field testing, combining three concepts and technologies. It features early glaucoma detection capabilities, glaucoma characterization tools, and management tools. 


It can function as an in-office glaucoma screener. It uses up to 69 stimuli that help eye doctors identify issues in the visual field. It has a glaucoma asymmetry test serial overview software that allows doctors to chart changes over time. 


 

Origin of the Humphrey



Before there was technology for visual field testing, eye doctors had to do it manually. They used a standardized test that Hans Goldmann designed, the Goldmann perimetry. The test used the same stimuli and background, allowing doctors to communicate about perimetry similarly. 


Zeiss designed the Humphrey to help doctors achieve better communication of data about perimetry. It was built on the ideas of the Goldmann perimetry testing strategies. It made them much more efficient and applied better analytical methods. 


 

How Does It Work?



The device works by imaging one cell layer on the cornea. It has a specular microscope that allows the eye doctor to examine the morphology of the cells. This will enable them to look for anomalies that indicate trauma. It can detect eye conditions like glaucoma, uveitis, and Fuch's dystrophy.
