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.
