(Visual) Field of Endeavor
Will the VF test remain stuck in the last century while virtual reality and eye-tracking technology race ahead in this one?
Visual field (VF) testing has seen many advances in information gathering systems and analysis techniques over the last decades – yet the most commonly used test procedure has changed very little during this time. In brief, the patients must fixate their gaze, keep their head still and accurately report detection of visual stimuli at different points in the field of view. As Pete Jones points out, most of the hard work is done by the patient, rather than the device. But not for long.
We've profiled innovations that are intended to assess vision in children too young to effectively use standard automated perimetry. We share the work of Tariq Aslam – inventor of Caspar’s Castle; we speak to Pete Jones, David Crabb and Dan Lindfield about Eyecatcher, a novel device from the Crabb Lab (London, UK); and we ask Chris Johnson (University of Iowa) about his own work, past and present, as well as his vision for the future. They all share a single view point: the status quo is no longer an option.
