Retinoscopy is an invaluable technique to obtain an objective estimation of the refractive error. The practitioner uses dynamic visual information and expertise requires a lot of practice over time. Conventional retinoscopes do not have the capabilities that would allow optometry instructors and students to view at the same time.
An off-the-shelf video-see.through HMD system is attached to a commercial retinoscope. A pinhole video camera is used as the vignetting observation pupil. The video output was displayed in the HMD (to the instructor) and can be recorded and visualized in real time as well as displayed on a video display for students to view.
The instructor had the same that the students had at the same time, giving importance to the reflex dynamics and case particularities.The system was used in the initial practical course of the Optometry Degree at the University of Murcia. Trainers filled a questionnaire for feedback. Lastly, videos of practice demonstrations have been recorded.
The system has been considered as very useful in practical retinoscopy training, and good video material is easily obtained for case reviews
