Smartphone Disc Photography Versus Standard Stereoscopic Disc Photography as a Teaching Tool.

Abstract

Optic disc photographic assessment was performed using an unmodified iPhone Xs Max. A video recording of the disc and peripapillary area was obtained in 5 patients. Good quality screenshots were acquired from the video, and, from them, a single best quality image was selected. This was compared with their respective standard optic disc stereo photograph. A glaucomatologist blinded to the type of image acquisition studied these images and concluded that both images could help well in the identification of glaucomatous optic disc features; however, the stereo photograph had better clarity than the iPhone static image. Nevertheless, the iPhone offered the advantage of real-time video assessment of the disc and peripapillary area and could serve as a practical and handy tool for telemedicine and teaching purposes.
