Title

Routine use of air tamponade in pars plana vitrectomy for primary rhegmatogenous retinal detachment repair

Purpose	Purpose: to establish if air can be considered as a safe substitute to longer lasting tamponade agents for primary rhegmatogenous retinal detachment (RRD) treatment, regardless of the position or the number of retinal breaks.
Methods	Methods: analysis of 230 consecutive patients (236 eyes) who underwent a pars plana vitrectomy (PPV) for primary RRD with air or SF6 tamponade from January 2014 till March 2020. The main outcome measure was the rate of an anatomically attached retina without the presence of any tamponade agent for at least 3 months post-operatively.
Results	Results: Our overall success rate in treating RRD with PPV in cases involving superior, inferior but also multiple breaks with air tamponade is 87.9% (145/165 eyes) and 80.3% (57/71 eyes) with SF6 20% tamponade. Very little pre-operative characteristics were found between the two groups.
Conclusion	Conclusion: As SF6 tamponade showed no better results, air tamponade seems a safe and effective agent for the treatment of primary rhegmatogenous retinal detachment, under the premise of thorough removal of vitreous traction, aspiration of sub-retinal fluid (SRF), and sealing of all the retinal breaks regardless of their localization.
