Zeiss Humphrey Matrix

This used Zeiss Humphrey Matrix is a frequency doubling technology perimeter designed for efficient screening and monitoring of visual field loss, particularly in early glaucoma detection. It uses a distinct testing methodology from standard automated perimetry, applying flickering sinusoidal gratings to stimulate specific visual pathways that are often affected early in glaucomatous disease, which can help identify defects before they are apparent on conventional perimetry. This makes it a useful complementary tool in a comprehensive glaucoma diagnostic workflow. The Matrix offers a range of test patterns suited to both screening and full threshold assessment, with relatively short test times that improve patient comfort and clinic throughput. Its portable, compact design allows it to be placed in exam lanes without requiring extensive space, and its straightforward operation makes it accessible for technicians who may not have extensive perimetry training. Reports generated by the system assist practitioners in tracking visual field status over time. This previously owned unit is a good fit for ophthalmology and optometry practices looking to add an efficient glaucoma screening tool alongside standard perimetry equipment. It serves practices that want to expand their early detection capabilities for glaucoma and other optic nerve conditions without a large increase in testing time per patient.
