Clinical Analysis of the Diabetic Vitrectomy According to Preoperative Dialysis

ABSTRACT

To determine the difference of the results induced by preoperative dialysis, we analyzed the medical records of the patients who had undergone pars plana vitrectomy (PPV) for the treatment of proliferative diabetic retinopathy (PDR). Of 65 patients (74 eyes) in total, there was the functional success (FS final visual acuity> or =0.04) in 58 (78.4%), visual improvement of 2 lines or more (VI) in 55 (74.3%), central visual efficiency of 20% or more (VE) in 42 (56.8%), and anatomical success (AS) in 62 eyes (83.8%). The dialysis group with 16 patients(19 eyes) showed FS in 12 (63.2%), VI in 11 (57.9%), VE in 10 (52.6%), and AS in 14 eyes (73.7%). The non-dialysis group with 49 patients (55 eyes) showed FS in 46 (83.6%), VI in 44 (80.0%), VE in 32 (58.2%) and AS in 48 eyes (87.0%). There was more or less difference between the dialysis and non-dialysis group in AS, VI, VE and AS, but it was not significant on the statistics. Accordingly, there may not be significant effect of dialysis on the result of PPV for the treatment of PDR.
