Implantation Site of a Port Delivery System With Ranibizumab: Anterior Segment Optical Coherence Tomography Evaluation

Abstract

Purpose: To determine whether anterior segment optical coherence tomography (AS-OCT) can be used to obtain noninvasive high-resolution images for monitoring the implantation site of a port delivery system with ranibizumab (PDS). Methods: Six eyes from the Archway phase 3 trial were imaged with AS-OCT after surgical implantation of the PDS and at regular follow-up visits. Results: AS-OCT was helpful in monitoring the status of the overlying conjunctiva and Tenon capsule after implantation of the PDS. Minimal qualitative thinning was observed over the implants at the longest follow-up. No cases of conjunctival erosion were noted. Conclusions: AS-OCT can be used to help to monitor PDS implants and potential associated complications.
