Ceeable Visual Field Analyzer (CVFA^(TM) for the Portable, Comprehensive, and Tele-medical Assessment of Visual Performance over Time in Warfighters, Pilots, Veterans, and Civilians


We introduce a portable, easy-to-use, worldwide accessible (i.e., web-based), and comprehensive tele-medical visual performance assessment system – the Ceeable Visual Field Analyzer (CVFATM) – for warfighters, pilots, veterans, and civilians to: (1) Accurately and rapidly assess visual performance; (2) characterize visual performance and ocular conditions; and (3) detect the onset of ocular conditions to allow for timely countermeasures as well as patient follow-up over time. CVFA has been shown to be effective in multiple clinical studies. The technology is rapid (< 5 minutes per eye), easy (use of touchscreen), accurate (spatial resolution < 1 degree), non-invasive, and comprehensive. The system automatically characterizes visual field defects in real time to generate new diagnostic insight. The visual performance assessment system is readily adaptable to traditional clinical and non-clinical settings (e.g., in forward operating bases in the theatre). It is capable of rapidly assessing conditions affecting the visual performance of warfighters in the field, allowing for triage and timely application of therapeutic countermeasures. The enabling technologies are a low-cost tablet computer and Internet connection. Ceeable is deploying the technology on a global basis to patients who will benefit from monitoring changes in visual function.
