Creating a digital retinoscope by combining a mobile smartphone camera and a retinoscope.

We present our experience creating a digital retinoscope by combining a mobile smartphone camera and a retinoscope. We found this digital retinoscope to be useful for demonstrating and documenting abnormal retinoscopic reflexes in teaching retinoscopy. This report explains how the digital retinoscope is assembled and provides examples of the range of normal and abnormal reflexes that can be captured. A short video showcases the reflexes being obtained in real time.
