Ocular findings, surgery details and outcomes in proliferative diabetic retinopathy patients with chronic kidney disease

We investigated the influence of impaired renal function on fundus characteristics, pars-plana vitrectomy (PPV) details, and outcomes in patients with proliferative diabetic retinopathy (PDR). A retrospective cohort study We investigated a consecutive series of PDR patients who underwent PPV. The diabetic complications, previous photocoagulation, intravitreal injections before PPV, ocular findings during PPV, surgical details, short-term visual outcome and post-PPV complications were recorded and compared between patients with and without impaired renal function. 149 patients had normal renal function (67.7%), and 71 (32.3%) patients had impaired renal function; 85.4% of patients were identified with chronic kidney disease (CKD) during the preoperative assessment. Impaired renal function was related to hypertension (3.40[1.58-7.29], p = 0.002), incomplete pan-retinal photocoagulation (PRP) (3.18[1.50-6.72], p = 0.002), severe fibrovascular membrane (8.19[3.43-19.54], p
