Purpose: To describe 2 cases in which video endoscopy was combined with heads-up 3-dimensional (3D) visualization. Methods: The imaging modalities of the heads-up 3D visualization system and video endoscopy were combined by converting the endoscope’s S-Video output into a high-definition multimedia interface. The technique was used in 2 cases that included lens dislocation and endophthalmitis. Results: In the 2 cases, the heads-up split-screen view simplified the surgical setup. Simultaneously viewing the endoscopic image and widefield 3D image anecdotally appeared to improve ergonomics, help keep the probe oriented, and assist in guiding surgical movements endoscopically. Conclusions: These cases show the advantages of a heads-up 3D system to simultaneously view endoscopic and widefield images during ophthalmic endoscopy in vitreoretinal surgery.
