Long-Term Outcomes of Oral Anti-Tubercular Therapy in Patient with Tubercular Dacryoadenitis: A Case Series.

Purpose: To describe the clinico-radiological features and long-term outcomes in patients with tubercular dacryoadenitis (TbD)

Methods

Retrospective, observational study of TbD patients who underwent a thorough clinical examination, orbital imaging study, and tailored ancillary investigations. Polymerase chain reaction (PCR) and microscopy were done in specific cases. A 4-drug anti-tubercular therapy (ATT) was started and clinical response was monitored in all. Patients with a minimum follow-up of 6 months "off-ATT" were included.

Results

All patients were women and three presented with pain, blepharoptosis, and bilateral involvement. In all, ESR was raised, Mantoux test was positive and orbital imaging revealed enlarged lacrimal gland/s. Positive PCR and granulomatous inflammation on microscopy were seen in two patients. At a mean follow-up of 17.25 months, all women responded with no relapse or clinical recurrence.

Conclusion

Bilateral lacrimal gland enlargement, positive Mantoux & PCR with early response to ATT may provide sufficient evidence for diagnosing TbD.
