WitmerLab doctoral student Donald G. Cerio has been developing a technique called “virtual ophthalmoscopy” to model and measure the visual fields of vertebrates. This model provides a taste of the output from the process. It is one of several species with which we have been validating the virtual or “in-silico” workflow by comparing these results with in-vivo findings. Here, we modeled the visual field of Phalacrocorax carbo using the skull and interpupillary distance of OUVC 10982, a similarly sized double-crested cormorant, P. auritus. Blue represents contralateral overlap (binocular field), red represents the visual field of a single eye (monocular field), and grey represents the blind area. Yellow dots represent in-vivo data (Martin et al. 2008: http://bit.ly/2IFT05z), showing close correspondence of “virtual ophthalmoscopic” visual fields with those measured by Martin et al. in vivo. Further validation of in-silico “virtual ophthalmoscopy” will be published by Cerio soon.
