In a preliminary study presented at ARVO last year, researchers demonstrated a novel technique for managing extensive peripheral retinal ischemia and subsequently mitigating rebound edema while preserving most peripheral vision. Using UWF-FA to identify areas of nonperfusion in each quadrant and then importing this information into their panretinal laser system allowed the investigators to effectively navigate PRP treatment in the periphery. A larger, prospective study to evaluate the integrated use of the Optos 200Tx with a panretinal laser for the management of retinal ischemia and rebound edema is now underway.
