SMITH OBEAR and Leone in December 1967 reported the use of solid radiopaque glass beads (Pyrex) in the correction of enophthalmos associated with anophthalmos.1 The same beads were satisfactorily employed in three patients referred to us with extruding implants.
The common dictum when dealing with the dilemma of dehiscence of the conjunctiva and Tenon's capsule anterior to an implant is to accept ultimate extrusion of the prosthesis.2 The usual approach is then to replace the extruded implant with a smaller prosthesis in hope of obtaining healing and socket reformation. The postoperative results are frequent failure and reextrusion. Illif has obtained satisfactory socket formation by insertion of an inflatable silicone sphere into the area of the muscle cone through a lateral brow incision.3
The mechanics of a contracting socket are quite unpredictable and subject to a variety of factors including the presence of infection, the fibrotic alterations behind
