    Description of Event or Problem · 0

    A HEALTH CARE PROFESSIONAL PUBLISHED ORIGINAL ARTICLE WITH A PURPOSE EARLY TO LATE EXPLANTATION OF HYDRUS MICROSTENT MIGS DEVICE: A CASE SERIES. THE HYDRUS MICROS TENT WAS APPROVED BY THE FDA IN AUGUST 2018 FOR USE WITH CATARACT SURGERY TO REDUCE IOP IN PATIENTS WITH MILD TO MODERATE PRIMARY OPEN ANGLE GLAUCOMA (POAG). PIVOTAL CLINICAL TRIALS DEMONSTRATED ITS OVERALL SAFETY AND EFFICACY IN LOWERING IOP. HOWEVER, MISPOSITIONING OF THE IMPLANT CAN RESULT IN UVEITIS GLAUCOMA- HYPHEMIA (UGH) SYNDROME NECESSITATING DEVICE EXPLANTATION. HERE WE REPORT FOUR SUCH CASES AND THEIR ASSOCIATED CHALLENGES. WE ALSO HIGHLIGHT THE IMPORTANCE OF EARLY RECOGNITION OF POST-OPERATIVE COMPLICATIONS FOR EASE OF IMPLANT REMOVAL. THIS FILE WAS CREATED FOR A 75-YEAR-OLD FEMALE WITH A HISTORY OF BILATERAL CHRONIC ANGLE CLOSURE GLAUCOMA AND AGE-RELATED MACULAR DEGENERATION WAS REFERRED FOR CHRONIC GRANULOMATOUS UVEITIS WITH ELEVATED IOP AFTER CATARACT SURGERY WITH HYDRUS MICROSTENT IMPLANTATION IN THE LEFT EYE 8 MONTHS PRIOR. THE PATIENT COMPLAINED OF NO IMPROVEMENT IN VISION AFTER THE SURGERY AND HAD A HISTORY OF RECURRENT INFLAMMATION ON TAPERING TOPICAL STEROIDS. SHOWED CME WITH A CENTRAL MACULAR THICKNESS OF 405 MICROMETER. CONCLUSION: HYDRUS MICROS TENTS THAT ARE MISPOSITIONED CAN RESULT IN PERSISTENT UVEITIS-GLAUCOMAHYPHEMA SYNDROME. EXPLANTATION BETWEEN 2 WEEKS AND 11 MONTHS SUCCESSFULLY RESOLVED POST-OPERATIVE UVEITIS AND HYPHEMIA, BUT ALL CASES REQUIRED ADDITIONAL GLAUCOMA-HYPHEMIA SYNDROME. EARLY RECOGNITION IS IMPORTANT SINCE LATE REMOVAL WAS MORE CHALLENGING DUE TO THE IMPLANT BECOMING EMBEDDED IN THE IRIS.
