INTRODUCTION: To report a case of hyphema following a bleb needling revision in a PreserFlo MicroShunt® implantation. CASE DESCRIPTION: An 87 years-old man suffering from bilateral open-angle glaucoma was referred to our hospital with a diagnosis of unsatisfactory intraocular pressure (IOP) control in the right eye, despite the maximally tolerated medical therapy. The patient underwent PreserFlo MicroShunt® implantation in his right eye. About 2 months after the surgical procedure the IOP was raised due to bleb failure for subconjunctival scarring. A needling revision was performed at the slit lamp. During the procedure blood reflux through a PreserFlo MicroShunt® device from a filtering bleb to the anterior chamber was observed, causing an IOP rise. Treatment with oral acetazolamide, topical steroid, and antibiotic resulted in the complete resolution of the hyphema in 2 weeks and a significant lowering in IOP. CONCLUSION: This is the first reported case of blood reflux to the anterior chamber through a PreserFlo MicroShunt® implant following a needling procedure.
