51. Concept

  • Motility and support are best with direct connection between implant and artificial eye

Direct coupling delivers all avalable movement to the artificial eye.

52. Composite photo showing the motility achieved in the first patient to receive a Bio-eye Hydroxyapatite Orbital Implant. This patient received the implant in 1985.

53. Bone scan illustrating little or no uptake of technetium 99 into the implant, which indicates the presence of little or no fibrovascular tissue. In such cases, the implant is not ready to receive a motility/support peg. More time is required for the implant to vascularize further.

54. Bone scan showing poor uptake of technetium 99 in the patient's left orbit. The uptake in the left orbit is slightly less than the uptake in the right orbit. This would be graded 1+, and the implant is not ready for the hole placement.

55. Bone scan showing adequate uptake of technetium 99 in the patient's left orbit. The uptake is half way between that of the mid-facial bones (center peak) and the normal orbit, which is graded 2+, the minimum grade required for hole placement in the implant. The central peak always represents the mid facial bones.

56. Bone scan showing good uptake of technetium 99 in the patient's right orbit. The uptake is equal to that of the mid facial bones. This is graded 3+, and this implant is ready for a peg hole placement. A grade of only 2+ is required for hole placement in the implant.

57. Bone scan showing excellent uptake of technetium 99 in the patient's left orbit. The uptake is graded 4+, since it is higher than that of the mid-facial bones.

58. Bone scan showing excellent uptake of technetium 99 in the patient's right orbit. This is graded 4+. A grade of only 2+ is required for peg hole placement in the implant.

59. An MRI with gadolinium contrast agent showing the uptake in a Bio-eye orbital implant. The peg hole and artificial eye appear as dark regions in this scan.

60. An MRI with gadolinium contrast agent showing the uptake in a Bio-eye orbital implant. Note robust vascularization in the posterior portion of the implant and around the peg hole.
