[Four cases of late infection following scleral buckling procedure].

We report four cases with late infection following a scleral buckling procedure. These cases were a 44-year-old male, a 52-year-old female, a 59-year-old male, and a 60-year-old male. All of these cases developed conjunctival injection, chemosis, and mucopurulent discharge 7 to 15 years after the procedure. The symptoms did not improve despite months of medical therapy, suggesting scleral buckle infection, and finally the buckling materials were removed. Solid silicone was used in 2 cases, and a sponge was used in 2 cases, with encircling elements in 1 case, and without encircling elements in 3 cases. Pus culture of the removal exoplant revealed fungaul infection in 2 cases. The others were negative, but bacterial infection was suspected from their clinical course and intraoperative findings. After removal of the buckles, the symptoms improved rapidly in all cases and there was no recurrence of retinal detachment. Scleral buckle infection should be suspected and removal of buckling materials should be considered, in cases with refractory conjunctival and scleral inflammation even years after scleral buckling procedure.
