Outcomes of transconjunctival 23-gauge vitrectomy for diabetic tractionnal retinal detachment.

Introduction: The transconjunctival 23-gauge vitrectomy without sutures (VTCSS) combines the advantages of the 20 and 25-gauge system. It currently represents the gold standard for the surgical management of vitreoretinal pathologies, especially in diabetic patients.
Aim: Evaluate the anatomical and functional results of the VTCSS 23 gauge in diabetic tractionnal retinal detachment (DRT).
Methods: This is a retrospective study of patients undergoing vitrectomy 23 gauges from February 2015 to February 2017. Each patient a complete ophthalmological examination with collection of  pre operative peroperative and postoperative data. The vitrectomy was performed by 3 ways through the 23-gauge cannula system Results :We collected 52 eyes presenting a DRT. The average age of patients was 50.62 years old. The average glycated hemoglobin (HBA1C) was 9.3%. The average time to treatment was 76.92 days. The results were as follows: For anatomical results: anatomical success rate was 92.30%. Functionally: A significant improvement in mean AV from 1/80 to 1.25 / 10 after surgery (p = 0.022), a statistically significant correlation between the final postoperative VA and the management delay (p <0.001); significant correlation between preoperative VA and final postoperative VA (p <0.001).
Conclusion: The VTCSS 23 gauge is an effective and safe surgery for DRT  surgery in diabetic patients with a gain in time and comfort for the patient.
