In the fourth article of this series,1 we discussed reoperations following scleral bucklings. The technique described in that article has been modified to the extent that we no longer use polyethylene tubing in operations for retinal detachment. The reasons for this change have been given in a previous publication.2 Silicone rubber is now used in all our scleral buckling procedures. It is particularly useful in reoperations because its elasticity and soft consistency prevent pressure necrosis even when it is placed over previously diathermized sclera. Special precautions to be taken in any kind of reoperation for retinal detachment have already been described3 and have not changed substantially with the advent of silicone rubber.
A correct reoperation of any kind cannot be performed unless the surgeon understands the cause of failure of the first operation. For this reason, we will first discuss various types of failure of retina surgery.
