Comparing Virtual Field and Humphrey Visual Field Testing

Reliable and accurate visual field testing is incredibly important. Eye care professionals use exam results to make critical diagnoses and patient treatment decisions. Here's how Virtual Field's visual field testing compares to the Humphrey Field Analyzer (HFA) and Humphrey Visual Field (HVF) 24-2 SITA testing, the current gold standard.

Multiple studies have demonstrated strong agreement between Virtual Field and Humphrey testing. Some examples include the Investigative Ophthalmology & Visual Science’s reports comparing VVF vs. HVF in an academic ophthalmic practice and VVF vs. HFA testing in glaucoma and optic nerve disease. Similarly, the American Society of Cataract and Refractive Surgery reported a comparison between VVF and HVF in a comprehensive ophthalmology practice.

These studies have shown comparable results in terms of mean deviation (MD), visual field index (VFI), and pattern standard (PSD). This indicates that Virtual Field delivers accuracy on par with the established Humphrey testing.

However, Virtual Field offers distinct advantages that enhance the patient experience and workflow efficiency. 

  • Cost Effectiveness: Virtual Field testing is significantly faster, typically taking just two to four minutes per eye compared to the Humphrey’s standard five to seven minutes. This translates to reduced patient chair time, which can potentially allow you to see more patients in a day and benefit your bottom line.
  • Portability, Mobility and Accessibility: Virtual Field's visual field exam devices are designed for accessibility, ease of use and patient comfort. The immersive virtual environment eliminates the need for cumbersome headrests and chinrests, potentially reducing patient anxiety and improving accessibility, comfort and test reliability. The device’s design also aids in portability and mobility, as it can easily be maneuvered around the exam room. This can be especially advantageous for patients that can’t reasonably access the standard tabletop perimeter. The headset itself also offers audio instructions in 38 languages which enables non english speakers to test with ease. 
  • Efficiency: Virtual Field offers real-time feedback during testing, allowing you to adjust the examination as needed. The headset itself handles occlusion, so removing the need for an eye patch can result in more efficient exams. Additionally, the system automatically generates progression analysis reports after just two examinations on the same eye. This facilitates close monitoring of visual field changes over time, aiding in the detection and management of glaucoma and other eye diseases.

In conclusion, Virtual Field provides a compelling alternative to Humphrey visual field testing. It delivers comparable accuracy in a faster, more patient-friendly, and efficient manner, empowering you to deliver exceptional eye care to your patients.

Streamlining Visual Field Testing with Virtual Field’s BOLT Algorithm

Virtual Field's introduction of the BOLT algorithm in 2019 marked a significant advancement in eye care technology. As mentioned, this proprietary thresholding algorithm *reduces exam times by nearly half, taking a mere three to five minutes per eye compared to the industry standard of five to seven minutes. Notably, BOLT achieves this efficiency without sacrificing accuracy.

The secret lies in BOLT's intelligent analysis. BOLT strategically assesses specific areas based on real-time patient responses. This intelligent approach prioritizes locations requiring further evaluation while efficiently gathering data from regions with sufficient information.

Imagine a map: BOLT doesn't meticulously check every square inch. Instead, it focuses on areas with potential roadblocks or detours, ensuring a clear overall picture without unnecessary exploration. This targeted strategy streamlines the testing process while ensuring reliable results. This versatility extends to three monocular patterns (24-2, 10-2, and 30-2), making BOLT a valuable tool for a wide range of eye examinations.

These advantages are further illustrated by real-world case studies.These examples showcase how the algorithm has revolutionized practices by boosting patient satisfaction and enabling more precise diagnoses.

Simplifying Progression Analysis with Virtual Field’s Visual Field Index Chart

Virtual Field sets itself apart by offering the only virtual perimeter with integrated, advanced progression analysis software. This valuable tool empowers you to closely monitor patients experiencing visual field changes, a crucial step in the management of glaucoma and other eye diseases.

Following just two BOLT examinations on the same eye, Virtual Field automatically generates a comprehensive visual field index chart. This intuitive chart allows you to visually assess potential progression over time and discuss it clearly with your patients. 

By incorporating progression analysis into your routine clinical workflow, Virtual Field equips you to proactively manage patients at risk of vision loss. Early detection is paramount in preserving visual function, and Virtual Field's progression analysis software empowers you to identify potential issues sooner, allowing for timely intervention and improved patient outcomes.
