Up for sale is this used ophthalmic visual-field perimeter. It was taken from a retiring optometry practice that still used it. It is in excellent condition and comes exactly as shown. This unit can be bolted onto an existing table. We can also provide a table if absolutely needed. But....why would you use a vintage manual perimeter instead of a field analyzer? Turns out, there are reasons!
Reasons to choose a vintage or traditional tabletop perimeter:
Longitudinal Data Continuity: The primary reason is that many patients have 10-20+ years of data on a specific, traditional machine like this one. Switching to a new technology requires a "re-baselining" process, which can obscure subtle disease progression.
Gold Standard Validity: Traditional bowl perimeters are the established gold standard, offering robust, peer-reviewed accuracy for detecting and monitoring glaucoma and retinal defects.
Reduced Test-Retest Variability: Traditional machines, particularly the HFA, may have higher correlation for test-retest variability compared to some newer, portable alternatives.
Kinetic Perimetry Capability: For certain patients with severe, advanced visual field loss, or specific, complex neurological or retinal conditions, manual goldmann perimetry is considered superior, as it allows for precise, examiner-guided mapping of the peripheral visual field.
While newer systems, such as virtual reality (VR) headsets, offer significantly faster, portable, and more comfortable experiences, traditional, older machines remain essential for ensuring consistent, long-term monitoring in chronic, progressive eye diseases.
