To report visual acuity and anatomic outcomes in patients undergoing pars plana vitrectomy (PPV) reoperations for complications of proliferative diabetic retinopathy (PDR).
Retrospective chart review of patients with diabetic retinopathy undergoing PPV between 2015 and 2018 at a university referral center. Patient charts were reviewed for indication for initial and repeat PPV, baseline clinical characteristics including gender, age, and lens status, and pre- and post-operative best-corrected visual acuity.
Of 538 eyes undergoing a PPV for diabetic retinopathy, 153 (28.4%) eyes had reoperation. Among the 130 eyes that met the inclusion criteria, 55 eyes underwent reoperation for complications of PDR, defined as non-clearing (NCVH) and/or tractional retinal detachment (TRD). Within this subgroup of 55 eyes, 19 (34.5%) eyes had an indication for the first surgery of NCVH. Fourteen (73.7%) of these NCVH eyes achieved a visual acuity of 20/80 or better. When the indication for the first surgery was TRD (32 eyes, 58.2%), 8 (24.2%) eyes achieved this same outcome (p=0.0011).
Approximately one of every four eyes treated with PPV for PDR will undergo repeat PPV during follow up. VA outcomes after the repeat PPV were variable, with NCVH cases achieving better outcomes compared to TRD.
