Outcomes of 23-Gauge Transconjunctival Sutureless Vitrectomy in Patients with Diabetic Retinopathy.

This study evaluated the anatomical and functional results of 23-G transconjunctival sutureless vitrectomy (TSV) in diabetic retinopathy (DR) patients with a variety of vitreoretinal diseases. Consecutive patients who underwent 23-G TSV for complications of DR were evaluated retrospectively. The primary outcome measures were best-corrected visual acuity (BCVA), intraocular pressure (IOP), and intraoperative and postoperative complications. A total of 42 eyes of 41 patients were included and followed up for a mean of 15.64±10.0 months. The mean patient age was 59.33±7.4 years. Indications for surgery were nonclearing vitreous hemorrhage (VH) (n=10), tractional retinal detachment (TRD) (n=8), TRD+VH (n=12), epiretinal membrane (n=5), diabetic macular edema (n=3), submacular hemorrhage (n=2), macular hole (n=1), or vitreomacular traction (n=1). There was a significant improvement in the BCVA at the postoperative first and third months, and at the last visit compared with the preoperative value (p<0.001). There was no significant change in the mean IOP measured on the postoperative first day, first week, first month, third month, or the last visit (p>0.05). In the postoperative period, the VH resolved spontaneously in 9 eyes. Repeat 23-G vitrectomy was performed in 6 eyes: 4 with recurrent retinal detachment and 2 with VH. The results indicate that 23-G TSV is an effective technique for vitreoretinal disease in patients with DR.
