Orbital pathology associated with diabetes mellitus

Diabetes mellitus may be associated with or result in diverse orbital and adnexal problems. It may include mild manifestations, such as blepharoptosis, blepharitis, xanthomas, increased tear-film glucose levels, and calcification of the trochlear apparatus. More severe findings involve third, fourth, and sixth cranial neuropathies. Finally, the physician always should be alert for the possibility of orbital infections in the diabetic population, especially the life-threatening rhinocerebral mucormycosis.
