Non-drainage surgery for retinal detachment.ʹ a prospective study in Khalili Eye Hospital

Introduction: Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment (RD), and of the simplest methods of treatment is non-drainage (minimized) surgery without drainage of subretinal fuid (SRF). We aimed to investigate the results of non-drainage retinal reattachment surgery in the patient with RRD, and to assess the anatomical and functional results of this technique. Method: Thirty cases (aged 9-70 years) with RRD were operated and followed for six months. The method of surgery was segmental buckling with or without encircling band, but SRF was not drained and allowed to be absorbed spontaneously.Chorioretinal adhesion was induced by cryotherapy around the breaks. Results: In 28 eyes (93%), SRF was absorbed during the first postoperative week. Two cases remained detach due to technical failure (inadequate buckle or hole out of the buckle). Subretinal hemorrhage and retinal incarceration was not seen in any of the cases. Five cases (16.6%) developed redetachment 1-3 month after operation. The reason was new hole formation in 3 cases (9.9%) and PVR in 2 cases (6.6%). Overall, 7 cases underwent reoperation (2 cases simple RD surgery and 5 cases deep vitrectomy) and finally, only in two cases retina remained detached (due to severe vitreous traction and multiple holes or tears). Conclusion: In cases with no or mild vitreous traction and definite accessible hole, this method is preferred, and the same anatomical and functional results can be achieved A long term large series study is required to evaluate the superiority of this technique over conventional method.
