The orbital volume after enucleation or evisceration might shrink over time due to atrophy of the orbital fat and connective tissue. This can lead to prosthesis misfit and an unsatisfactory cosmetic result. This so-called post enucleation socket syndrome (PESS) needs a secondary orbital volume augmentation. The techniques for orbital volume augmentation are secondary orbital implants or implant exchange, orbital floor implants or injectable augmentation. The surgical possibilities are described and discussed with special attention to indications and chances.
