PURPOSE: To describe methods for improving visualization of the port delivery system (PDS) with ranibizumab (Susvimo) during the refill-exchange procedure when visualization of the implant septum is compromised.
METHODS: Multiple methods of PDS visualization using external illumination were evaluated.
RESULTS: Transpupillary and transscleral illumination of the PDS reservoir body using various light sources improved visualization of the implant septum during the refill-exchange procedure.
CONCLUSIONS: Indirect internal illumination of the PDS implant can facilitate visualization of the implant septum during the refill-exchange procedure, particularly when visualization is compromised by conjunctival edema, thickened Tenon capsule, or fibrous capsule formation.
