title = "Measurement of visual strain in radiologists",
abstract = "We hypothesized that the current practice of radiology produces oculomotor fatigue that reduces diagnostic accuracy. The initial step in testing this hypothesis is to measure visual strain. We are approaching this by measuring visual accommodation of radiologists before and after diagnostic viewing work. We measure accommodation using the WAM-5500 Auto Refkeratometer from Grand Seiko, which collects refractive measurements and pupil diameter measurements. The radiologists focus on a simple target while accommodation is measured. The target distances are varied from near to far starting at 20 cm target distance from the eye to 183 cm. The data are compared for prior to and after long-term diagnostic viewing. Results indicate that we are successfully measuring visual accommodation. Accommodation at long distances does not seem to differ before and after diagnostic reading. Accommodation at near distances however does differ, with decreased ability to accommodate after many hours of diagnostic reading. Since near distances are crucial during diagnostic reading, this could have a substantial impact on diagnostic accuracy (the next phase of the project).",
