An unusual complication of retinal reattachment surgery

The authors report a case with an unusual late extraocular complication of scleral buckling and local silicone sponge implant. Four years after the re attachment surgery, a ptotic upper eyelid perforated by local silicone spon ge implant and fistula between upper eyelid and sclera were detected. Prima ry repair of upper eyelid and removal of silicone sponge were performed. On e year later, the retina was attached and there was no problem with the upp er eyelid. Cryotherapy, episcleral explant (scleral buckling), and local implant (spon ge) are frequently used and effective methods for retinal reattachment surg ery.(1'2) Postoperative early and late complications have been reported.(3- 8) To our knowledge, there is no report of upper eyelid perforation, ptosis and fistula formation caused by silicone sponge implant rejection.
