Periorbital tuberculosis.

An observational case series of seven cases of periorbital tuberculosis, a rare tubercular presentation occurring in patients with and without systemic disease, is presented. Non-healing sinus and osteomyelitis of periorbital flat bones was observed. All cases had a positive Monteaux test and PCR. AFB cultures of the sinus discharge were negative. The response to triple-drug therapy was dramatic. Follow-up at the end of one year showed clinical recovery. The authors stress the need for a high index of suspicion in cases of non-healing lesions and atypical inflammatory presentation in the periorbital region.
