Case report: Surgical management of vitreous obstruction following PreserFlo ® MicroShunt implantation
Purpose: To describe a clinical case of lumen obstruction a few days after implantation of the PreserFlo® Microshunt which has been resolved by anterior vitrectomy. Observation: A 76-year-old patient with advanced and progressing primary open-angle glaucoma (POAG) presented ten days after PreserFlo®...

| description | Purpose: To describe a clinical case of lumen obstruction a few days after implantation of the PreserFlo® Microshunt which has been resolved by anterior vitrectomy. Observation: A 76-year-old patient with advanced and progressing primary open-angle glaucoma (POAG) presented ten days after PreserFlo® Microshunt implantation in his left eye with an intraocular pressure (IOP) of 24 mmHg because of vitreous obstruction. Anterior vitrectomy with 25 Gauge vitrector was performed to remove the vitreous using a bimanual technique with two corneal accesses. The surgery was successful in lowering uncontrolled IOP without device repositioning. A free lumen and a IOP in the low range of tens was observed during follow-up. Conclusions and importance: PreserFlo ® MicroShunt obstruction by vitreous in pseudophakic patient is a possible complication. Anterior vitrectomy without the need of tube repositioning was successful in lowering uncontrolled IOP. |
