Title

Repair of primary rhegmatogenous retinal detachment using 23-gauche transconjunctival sutureless vitrectomy

Purpose	To evaluate and compare the anatomical outcomes of primary rhegmatogenous retinal detachment repairs performed either using 23-Gauche transconjunctival sutureless vitrectomy or 20-Gauche vitrectomy.
Methods	A retrospective, comparative interventional case series including 116 consecutive eyes of 116 patients who underwent a 23-Gauche transconjunctival sutureless vitrectomy to repair primary rhegmatogenous retinal detachment and 214 consecutive eyes of 214 patients who had a 20-Gauche repair for primary rhegmatogenous retinal detachment. All patients were operated by the same surgeon. Outcomes were single-operation anatomical success rate, final anatomical success rate, postoperative visual acuity and surgical complications.
Results	Using the 23-Gauche systems, the retina was reattached with a single operation in 105( 91 %) of 116 eyes. The final anatomical success rate was 100 %. The mean time to redetachment was 5 weeks. Proliferative vitreoretinopathy and development of new retinal breaks were the most common reasons associated with redetachment.
Conclusion	Repair of primary rhegmatogenous retinal detachments using 23-Gauche transconjunctival sutureless vitrectomy results in excellent final anatomical success rate. A high incidence of redetachement was found when the primary detachment was located in the inferior quadrants. Therefore, to repair the majority of retinal detachements, 23-Gauche vitrectomy is now used in our centre.
