Reflux hyphema from transient hypotony after Ozurdex® in eyes with prior GATT

PURPOSE: To report on delayed-onset hyphema following intravitreal injection of dexamethasone implant Ozurdex® in eyes with a history of gonioscopy-assisted transluminal trabeculotomy (GATT). OBSERVATIONS: We describe two cases of hyphema occurring within one day following Ozurdex® implantation in eyes that had undergone GATT at least one year prior. One case responded well to medical management, while the other required anterior chamber paracentesis for intraocular pressure (IOP) control. Both patients achieved normalization of IOP following resolution of the hyphema, and have not had recurrence. CONCLUSIONS AND IMPORTANCE: We propose that transient hypotony immediately after Ozurdex® injection may lead to a reflux of blood from the episcleral venous network into the anterior chamber in eyes with prior ab interno trabeculotomy. Glaucoma and retina specialists should be aware of this potential complication to guide follow up and management in the post-injection period for these patients.
