Purpose: Tubercular intermediate uveitis (TIU) and panuveitis (TBP) are difficult to manage because of limitations in diagnostic tools and lack of evidence-based treatment guidelines. The Collaborative Ocular Tuberculosis Study (COTS) analyzed treatment regimens and therapeutic outcomes in patients with TIU and TBP. Methods: Multicentre retrospective analysis. Results A total of 138 TIU and 309 TBP patients were included. A total of 382 subjects received antitubercular therapy (ATT) (n = 382/447; 85.4%) and 382 received corticosteroids (n = 382/447; 85.4%). Treatment failure was observed in 78 individuals (n = 78/447; 17.4%), occurring less frequently in patients receiving ATT (n = 66/382; 17.2%) compared to those who did not (n = 12/65; 18.5%). The study did not show any statistically significant therapeutic effect of ATT in patients with TIU and TBP. Conclusion Taking into account the limitations of the retrospective, non-randomized study design, resultant reliance on reported data records, and unequal size of the samples, the current study cannot provide conclusive evidence on the therapeutic benefit of ATT in TIU and TBP.

Purpose: Tubercular intermediate uveitis (TIU) and panuveitis (TBP) are difficult to manage because of limitations in diagnostic tools and lack of evidence-based treatment guidelines. The Collaborative Ocular Tuberculosis Study (COTS) analyzed treatment regimens and therapeutic outcomes in patients with TIU and TBP. Methods: Multicentre retrospective analysis. Results A total of 138 TIU and 309 TBP patients were included. A total of 382 subjects received antitubercular therapy (ATT) (n = 382/447; 85.4%) and 382 received corticosteroids (n = 382/447; 85.4%). Treatment failure was observed in 78 individuals (n = 78/447; 17.4%), occurring less frequently in patients receiving ATT (n = 66/382; 17.2%) compared to those who did not (n = 12/65; 18.5%). The study did not show any statistically significant therapeutic effect of ATT in patients with TIU and TBP. Conclusion Taking into account the limitations of the retrospective, non-randomized study design, resultant reliance on reported data records, and unequal size of the samples, the current study cannot provide conclusive evidence on the therapeutic benefit of ATT in TIU and TBP.
