The Collaborative Ocular Tuberculosis Study (COTS) Consensus (CON) Group Meeting Proceedings

Diagnosis and Treatment of Tubercular Uveitis in Taiwan - Consensus of Expert Panels

There is currently a lack of guidelines with regard to tubercular uveitis (TBU) management in Taiwan. We therefore propose an evidence-based consensus on the management for TBU. The Taiwan Ocular Inflammation Society conducted a meeting that included nine ophthalmologist and one infection disease expert that focused on three broad areas of (1) nomenclature for TBU, (2) assessment and diagnosis for TBU, and (3) treatment of TBU. Brief literature review on TBU diagnosis and management was conducted that informed this panel meeting in order to make decisions on each consensus statements. In terms of our results, a consensus statements and recommendations for the diagnosis and management of TBU were developed. This consensus statement provides an algorithmic approach toward diagnosing and managing TBU. These statements are meant to enhance but not replace individual clinician-patient interactions and to facilitate real-world clinical practice improvement in terms of TBU patients care.

Photodynamic Therapy for the Treatment of Vascularized Intraretinal Tuberculoma

PURPOSE

To report a case of intraretinal tubercular granuloma successfully treated with photodynamic therapy (PDT).

METHODS

Retrospective case report. Multimodal imaging was performed at each follow-up visit.

RESULTS

The tuberculoma did not regress and did not significantly reduce its exudation after anti-tubercular therapy (ATT), systemic steroid therapy and intravitreal anti-VEGF. Second line treatment with PDT was attempted. The lesion showed a regression with reduced sub-retinal fluid and intra-retinal exudates. A second PDT was performed for reactivation of the lesion 5 months after the first treatment. Further regression of the lesion was observed.

CONCLUSION

PDT may be a valuable second-line therapeutic approach for vascularized intraretinal granulomas.

Tuberculosis-Related Uveitis in Patients under Anti-TNF-alpha Therapy: A Case Series

Tumor necrosis factor inhibitors (anti-TNF) have emerged as an effective treatment in noninfectious uveitis (NIU). Anti-TNF may increase the predisposition to infectious disease as tuberculosis (TB). TB-related uveitis in the context of an uveitogenic concurrent systemic immune-mediated disease under anti-TNF treatment remain a diagnostic challenge, deserving special focus on this rare context. Retrospective chart review of patients on anti-TNF drugs for systemic immune-mediated diseases that developed a multicentric microbiologically confirmed active TB with concurrent intraocular involvement.Three patients were recorded. Screening for TB before starting anti-TNF resulted negative in two patients. The other patient had received anti-tuberculous treatment in the past. All showed a microbiologically confirmed extraocular TB after unexpected atypical reactivation of the uveitis shifting to chronic granulomatous pattern.Specialists should be aware of TB reactivation, even with previous negative screening, when ocular uveitis signs and activity do not match with the expected pattern in a patient on anti-TNF drugs.
