Materials and methods: Fifty-nine eyes of 54 patients who underwent surgery for diabetic tractional RD between January 2015 and April 2016 in our clinic were included in the study. The fi les of the cases were examined retrospectively. Age, gender, duration of silicone oil endotamponade, best corrected visual acuity (BCVA), intraocular pressure (IOP), redetachment rate and other postoperative complications were evaluated.

Results: 35 of the patients were female (64.8%) and 19 were male (35.2%). The mean age was 59.1 ± 10.2 (29-80) years. The preoperative mean BCVA was 0.06 ± 6.6 (0.03-0.4), while the postoperative mean BCVA was 0.10 ± 13.3 (0.03-0.7). The preoperative and postoperative mean IOP were 16.3 ± 6.04 and 14.3 ± 4.1 mmHg, respectively. The mean duration of silicone oil endotamponade was 6.8 ± 4.01 (2-24) months. Cataract surgery was performed in 31 (52.5%) patients as removing silicone oil endotamponade. Postoperative complications were transient severe hypotony in one eye (1.7%), transient hypertony in three eyes (5.08%), vitreous hemorrhage requiring surgery, hyphema and hypopyon in one eye (1.7%) and redetachment in four eyes (6.8%).

Conclusion: In patients who underwent pars plana vitrectomy and silicone oil endotamponade due to diabetic tractional retinal detachment, ocular hypotonia or hypertonia and vitreous hemorrhage may rarely develop, besides retinal redetachment, following removal of silicone oil endotamponade..
