Abstract

Purpose: To report a non-pharmacological complication occurred with the applicator of the dexamethasone intravitreal implant.

Case report: Report a case of a 76-year-old pseudophakic women treated with dexamethasone intravitreal implant (Ozurdex™, Abbvie) because of cystoid macular edema in the left eye. During the procedure a malfunction related to the mandrel during the injection procedure occurred. The mandrel of the device came out of the pen, becoming embedded in the sclera. As soon as the bar was visualized in the sclera, it was removed with the help of Adson forceps. No complications occurred in the retina.

Conclusion: The mandrel of the device could be more damaging than the micronized dexamethasone rod and can be propelled out with sufficient force and speed if it impacts on the contralateral retina. This can occur —as it did in this case— because the mandrel is attached by a plastic portion of only 0.1 mm to the rest of the piece.
