Among the 130 eyes (119 patients) that met the inclusion criteria, 55 eyes (50 patients) underwent reoperation for complications of PDR, defined as non-clearing vitreous hemorrhage (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 (33 eyes, 60%), 8 (24.2%) eyes achieved this same outcome (p=0.0011).Conclusion: 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.Keywords: vitreoretinal surgery, diabetic retinopathy, retinal detachment, retinaAl-khersan HVenincasa MJKloosterboer ASridhar JSmiddy WETownsend JHFlynn HWDove Medical Pressarticlevitreoretinal surgerydiabetic retinopathyretinal detachmentretinaOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 1559-1563 (2020)
