A port delivery system is a novel type of drug delivery platform using a permanent drug-eluting implant inserted into and through the sclera of the eye to allow delivery of drugs to the intravitreal space. Such systems consist of a transscleral device that includes a reservoir and release control element to distribute drugs within the eye. A self-sealing extrascleral flange, which is visible through the conjunctiva, allows refilling of the reservoir as needed. Port delivery systems have been proposed as an alternative to monthly intravitreal injections in the treatment of retinal and potentially other ocular diseases.

Position Statement

Investigational and Not Medically Necessary:

The use of a port delivery system to treat ocular disease is considered investigational and not medically necessary for all indications.
