This is the first reported case of blood reflux to the anterior chamber through a PreserFlo MicroShunt implant after a needling procedure.
Introduction:To report a case of hyphema after a bleb needling revision in a PreserFlo MicroShunt implantation. Case Description:An 87-year-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 because of 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. Conclusions:This is the first reported case of blood reflux to the anterior chamber through a PreserFlo MicroShunt implant after a needling procedure.
