Extract

To the Editor We read with interest Rahimy and Garg’s experience using Google Glass to film a scleral buckling procedure.1 We agree there is a need for better videography methods for ophthalmic surgery, and we have had success filming a scleral buckling procedure in stereo with 2 GoPro HERO cameras. The surgeon wore a 3-dimensional–printed plastic mount (http://www.thingiverse.com/thing:673214), which offset the cameras approximately 60 mm in the horizontal plane. We recorded at 1280 × 720-pixel resolution, 60 frames per second, with each camera filming simultaneously. We combined the files to create a stereoscopic video (Video 1 and Video 2) in the GoPro Studio software, which took approximately 1 hour. The resulting video is viewed side by side using a stereo viewer (Screen-Vu; Berezin Stereo Photography Products). Red-cyan anaglyph viewing is also possible (glasses at http://www.3dstereo.com), depending on how the file is saved, but this degrades the viewing experience because each eye receives different color channels.2
