Feasibility and acceptability of virtual reality visual field testing compared to standard perimetry

The authors present a prospective pilot study which aimed to assess the feasibility and performance of the vivid vision perimeter (VVP). The VVP is a piece of software which can be used with off-the-shelf virtual reality (VR) headsets. Recruitment took...

What plane should be used for ultrasound measurement of the optic nerve sheath diameter?

This prospective observational study aimed to evaluate the differences between optic nerve sheath diameter (ONSD) between the patients’ two eyes and different ultrasound planes (transverse and sagittal). Participants were recruited over a two-year period from a single neurosurgical department. To...

Artificial intelligence co-creation for educational learning tools and targeted simulators

Artificial intelligence (AI)-powered tools are becoming increasingly common within clinical practice and medical education, and using AI in simulation as a pure learning tool and for assessment has been widely discussed. Targeted, efficient use of such tools has been shown...
