Abstract

Background: The authors report two cases of the scleral buckles intrusion and erosion that presented many years after primary surgery with vitreous haemorrhage in one of them. Although the erosion/intrusion of a silicone scleral buckle (SB) is rare, it may have serious consequences and optimal management can be challenging. Therefore, this diagnosis should be considered if attributable signs and symptoms including vitreous haemorrhage occurred after scleral buckling. The authors briefly review the literature on clinical presentation and management of the episcleral silicone buckling erosion and intrusion. Case presentation: Case 1: A 48-year-old woman with a history of scleral buckling for an inferior rhegmatogenous retinal detachment presented with visual loss in her right eye. A vitreous haemorrhage was observed. After Close observation, Partial resolution of haemorrhage revealed an intruded sponge segment in inferior vitreous cavity. Case 2: A 26-year-old man was referred for retinal evaluation. Twenty years earlier, he had undergone lensectomy for bilateral childhood cataract. Ten years ago, he had developed an aphakic RRD in the left eye. The detachment was managed with pars plana deep vitrectomy, endolaser, an encircling silicone band, and silicone oil injection. On examination an eroded band was noted. Conclusion: Although the erosion/intrusion of a silicone episcleral buckle is rare, it may have serious consequences and optimal management can be challenging. Unnecessarily destructive techniques may predispose the eye to this complication and should be avoided. Patients who have a history of SB need lifelong follow-up and this diagnosis should be considered if attributable signs and symptoms occurred. © 2020 The Author(s).
