Evaluation of biomatrix hydroxyapatite ocular implants with technetium-99m-MDP.
Hydroxyapatite ocular implants appear to offer excellent cosmetic reconstruction with lower rates of infection and extrusion compared to other integrated implants. However, vascularization of the implant needs to be established before the artificial eye is attached to the implant. Technetium-99m-methylene diphosphonate (MDP) scintigraphy can be utilized as a noninvasive method for determining the vascularity of the hydroxyapatite ocular implants. A case is presented in which 99mTc-MDP uptake in the implant was deemed sufficient for further surgical intervention.
