Purpose: Scleral buckle (SB) removal is rarely performed due to extrusion, infection, or diplopia. We report a series of patients with recurrent retinal detachment (RRD) after primary SB due to new breaks occurring at sites where the presence of a pre-existing SB was judged counterproductive. All patients were treated by means of pars plana vitrectomy (PPV) and SB removal with the sole purpose of achieving a more favorable retinal profile.
Methods: We retrospectively reviewed all patients undergoing PPV and SB removal for RRD due to new breaks occurring at sites hidden by pre-existing exoplants.
Results: Mean age was 52 years and VA on presentation was 20/620 and 20/216 at latest visit (p<0.01), 23 months of follow-up. On presentation, 3/11 (27%) had a VA better than 20/400 and 1/11 (9%) better than 20/40. At the end of follow-up, 9/11 (81%) and 3/11 (27%) saw better than 20/400 and 20/40 (p<0.05). At the end of follow-up, 8/11 (72%) had an attached retina, 2/11 (18%) had a partially attached retina, and 1/11 (9%) had a total RD. Explanted buckles included 5 silicone sponges and 6 solid silicone rubber elements.
Conclusions: Although occasionally cumbersome and time-consuming, SB removal may provide a more favorable retinal profile and improve retina-tamponade contact. Larger series are needed to assess if this translates into a significant benefit in the treatment of selected RRD.
