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

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.

Evaluate the anatomical and functional results of the VTCSS 23 gauge in diabetic tractionnal retinal detachment (DRT).

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).

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.
