To evaluate the clinical outcomes according to silicone oil removal (SOR) time in severe proliferative diabetic retinopathy (PDR).
Among patients with a history of undergoing pars plana vitrectomy (PPV) and silicone oil tamponade for severe PDR, 48 patients (56 eyes) who underwent SOR less than 3 months after PPV and 34 patients (39 eyes) more than 6 months after PPV were included in this retrospective study. The period of silicone oil retention in the eye, best corrected visual acuity (BCVA) and intraocular pressure (IOP) prior to the SOR procedure and throughout the follow-up period, and postoperative complications were compared.
The mean preoperative logMAR BCVAs were 0.91 ± 0.41, 0.93 ± 0.34, mean last follow up logMAR BCVAs were 0.38 ± 0.27, 0.77 ± 0.39 (p<0.001, p=0.089, resp.), and mean preoperative IOPs were 11.72 ± 4.25 mmHg, 12.04 ± 3.37 mmHg, mean last follow up IOPs were 11.65 ± 3.78 mmHg, 11.89 ± 4.14 mmHg (p=0.831, p=0.594, resp.) when SOR underwent less than 3 months after PPV and more than 6 months after PPV, respectively. After SOR, vitreous hemorrhage occurred in 3 eyes (5.4%) and 10 eyes (25.6%), respectively (p=0.027). Eyes with SOR less than 3 months after PPV were significantly more likely to have a good visual prognosis.
Early SOR was more effective in visual recovery and minimizing complications of severe PDR patients.
