Abstract
Three cases are presented of anophthalmic patients with exposed orbital implants. Although only one patient showed evident clinical signs of infection, all three implants were studied to determine the presence of microorganisms adhered to their surface using a scanning electron microscopy (SEM) and microbiological culture. The SEM allowed the visualisation of microorganisms adhered to the three implants, although only one of them showed growth in the microbiological cultures. In addition, the SEM technique used in case No. 3 achieved a better orientation and appreciation of the microorganisms with respect to the images of cases No. 1 and 2. These findings support the idea that the surface of exposed orbital implants is colonised by microorganisms, even when they still do not show obvious signs of infection. Therefore, mechanical removal of the exposed surface of the implant is necessary before covering it with grafts or flaps.
