PURPOSE: To describe in-office suprachoroidal viscopexy(SCVEXY) as a novel adjunct surgical technique with pneumatic retinopexy(PnR) for rhegmatogenous retinal detachment(RRD). METHODS: A 61-year-old pseudophakic male who was failing PnR for a macula-involving RRD underwent rescue SCVEXY at St. Michael's Hospital, Unity Health Toronto, Toronto, Canada. RESULTS: An injection of suprachoroidal sodium hyaluronate 2.3% (Healon 5, Abbott Medical Optics) was performed at five o'clock under the causative retinal tear using a 30G needle with a custom-made-guard that exposed 1mm of the needle. Following the procedure, a dome-shaped suprachoroidal convexity was present in the inferotemporal quadrant. The patient achieved complete reattachment over two days with continued positioning. Laser retinopexy was applied around the causative tear, and the viscoelastic reabsorbed over a period of approximately two weeks. The retina remained attached until the final follow-up at nine months. CONCLUSION: SCVEXY is a minimally invasive in-office procedure that creates a temporary suprachoroidal buckle that can be used to rescue failing PnR in RRD. It can be particularly useful to close inferior tears, avoiding the need for operating room procedures such as pars plana vitrectomy or scleral buckle. However, there is still limited data on ideal case selection, efficacy, adverse events and failure rates.
