PURPOSE: To explore the feasibility and compare the outcomes of three wide-angle fundus cameras for imaging the peripheral retina through the Type 1 Boston keratoprosthesis. METHODS: The noncontact Optos and the contact RetCam and Panoret wide-angle imaging systems were used to image the retina of eyes implanted with a keratoprosthesis. The failure-to-image rate, ease of acquisition, and quality of the images were noted, and the field of view was compared. Limitations and complications were recorded. Optos was then performed on patients referred for ultrasound B-scan evaluation, and the imaging findings were correlated. RESULTS: Retinal images with all three cameras were obtained on four eyes. Optos could be performed on all four eyes, RetCam on three, and Panoret on two. The field of view was comparable between the three different cameras. The best quality images were obtained with Optos. The external illumination of the Panoret made it impossible to image the only darkly pigmented individual in the series. Both contact devices failed to image another patient who was too agitated. Two patients had some ocular irritation from the coupling agent that resolved with replacement of the contact lens. Optos images were obtained on an additional six eyes, and findings correlated well with those on B-scan. Optos was superior to B-scan in an eye with silicone oil filling. CONCLUSION: Wide-angle fundus imaging through the keratoprosthesis is possible, and all three cameras performed similarly. The good quality of pictures obtained with the noncontact Optos, as well as its ease of use, comfort, and safety make it a preferred choice. Optos complements B-scan in the examination of the peripheral retina through the keratoprosthesis, and it may even be superior in certain settings.
