Orbital tuberculosis.

Orbital tuberculosis (TB) is an extremely rare condition in North America. The authors present a case of TB involving the orbit, lower lid, and zygoma and review pertinent literature regarding orbital TB. Following excision of the orbital lesion, the patient responded well to anti-TB therapy. With the reemergence of TB associated with AIDS, orbital TB may be a more frequent presentation and should be considered in the differential diagnosis of inflammatory orbital disease.
