The analysis identified patients entered into the IRIS registry from 2013 through the second quarter of 2016 using ICD-9 and ICD-10 codes. Patients were excluded that had a CPT code with an unspecified eye or bilateral pathology.
In the overall cohort, about 11% of eyes had a scleral buckle, about 80% had primary vitrectomy with or without a buckle, and about 9% had a repair with a complex retinal detachment code. Success rates for those three procedures were 87.8%, 88.2%, and 85.1%, respectively.
High-risk or complex retinal detachment was defined by having codes for multiple breaks, total retinal detachment, giant retinal tears, or primary PVR. The procedures performed in the high-risk/complex cohort were similar to the overall population, with about 10% of eyes having a primary buckle, 77.5% having vitrectomy with or without a buckle, and almost 13% having a complex repair.
Success rates with scleral buckle and vitrectomy were not significantly different (86.4% vs. 86.8%), but both procedures were associated with a significantly higher success rate compared with a complex repair (85.9%).
