Optic disc topographic changes post-trabeculectomy visualised by anaglyphs

Background: Publications on changes of optic disc topography usually illustrate their findings with two-dimensional images.Methods: With the introduction of computerized imaging, anaglyphs of stereo images can be produced for illustrations. Anaglyphs are viewed three-dimensionally with red-green spectacles that are included in refraction sets and are normally used to assess phoria. An anaglyph of progressive, glaucomatous progression is included to demonstrate the method, along with conventional colour images.Results: We present two cases of severely altered optic disc topography post-trabeculectomy and illustrate these cases with anaglyphs that can be viewed three-dimensionallyConclusion: Three-dimensional viewing of illustrations assists with the visualization, perception and interpretation of optic disc changes.
