Review the history of anophthalmic socket surgery. Describe the development of implants for the anophthalmic socket. Become familiar with CT & MR imaging features of these implants. List the MR imaging safety profiles of some of the implants still in clinical use

The absence of the eye or its contents leads to major changes in the physiology and dynamics of the orbit as well as cosmesis and it is necessary to replace the orbital volume. In this pictorial review we explore the evolution of orbital implants for the anophthalmic socket through the 20th century. From glass to hydroxyapatite, we use CT & MR imaging to describe the development of bio-materials used in orbital implants. We also discuss the advantages and limitations of these implants including MRI safety of some the implants still in use

History:

Classification and type of implants:

CT & MRI features:

Non-integrated:
Glass
Polymethylmethacrylate (PMMA)
Silicone
Quasi-integrated:
Castroveijo
Roper-Hall magnetic implant
Baseball implant
Integrated:
Hydroxyapatite

This innovative pictorial review using CT and MR imaging describes the development of bio-material used in implants for the anophthalmic socket through the 20th century. The MRI safety features of some the implants are also reviewed. The role of CT and MR imaging examination of the anophthalmic socket and orbital implants is constantly expanding and we hope, this review will help in the development of new and safer implants
