The Open Perimetry Initiative: A framework for cross-platform development for the new generation of portable...

Area of Science:

• Ophthalmology
• Medical Technology
• Computer Science

Background:

• Clinical research in visual fields and perimetry faces barriers.
• The Open Perimetry Initiative (OPI) was established in 2010 to address these challenges.
• Existing tools lacked open-source accessibility and broad device compatibility.

Purpose of the Study:

• To introduce and showcase the capabilities of the Open Perimetry Interface (OPI) and its associated visualFields package.
• To present the new opiApp frontend for customizable visual field testing.
• To demonstrate the application of these open-source tools in developing and analyzing novel perimetry tests.

Main Methods:

• Development of the Open Perimetry Interface (OPI) with drivers for commercial perimeters, head-mounted devices, and virtual reality headsets.
• Creation of the visualFields package for comprehensive analysis and visualization of visual field data.
• Implementation of the opiApp frontend, enabling customized testing on devices like Octopus 900, Compass, AP 7000, IMO, and Android phones with virtual reality headsets via PhoneHMD.

Main Results:

• The OPI and visualFields package are fully open-source tools facilitating research.
• The opiApp supports multiple commercial perimeters and mobile virtual reality headsets.
• A custom static automated perimetry test for extended visual fields was successfully developed and analyzed using OPI and visualFields.

Conclusions:

• The Open Perimetry Initiative has significantly advanced perimetry research through open-source tools.
• The OPI, visualFields, and opiApp lower barriers to clinical research in visual fields.
• Continued collaboration with researchers, clinicians, and industry is crucial for the future of open science in perimetry.
