Delayed Orbital Haemorrhage with Possible Infectious Aetiology after Silicone Implantation

31



The principles of exploration and repair of orbital floor fractures are to restore the anatomical structure of the orbital wall to its original state (as much as possible), functional capabilities of the extraocular muscles and useful binocular single vision. Various materials have been used in the repair of such fractures, including autogenous (cartilage, bone) and alloplastic (e.g. Teflon®, Supramid®, silicone, titanium) implants. Delayed orbital haemorrhage following the use of alloplastic implants is an uncommon complication. Only 22 of such cases have been found in published medical literature between 1984 and 2005. This complication can surface anytime between 3 months and 20 years following implantation. However, none have reported infective components associated with delayed orbital haemorrhages. In the following report, we present 1 such case seen at the Singapore National Eye Centre, with isolation of coagulase-negative Staphylococcus from cultures taken intraoperatively.
