Tuberculous Scleritis and Multidrug Resistance.

PURPOSE: To present a case of necrotizing sclerokeratitis in a patient with multidrug-resistant tuberculosis and study the challenges in diagnosis and management of anterior tuberculous scleritis.

METHODS

Retrospective observational case report and review of anterior tuberculous scleritis.

RESULTS

A 28-year-old woman, previously diagnosed as presumed tubercular panuveitis, presented with necrotizing sclerokeratitis and progressed to develop panophthalmitis. Laboratory investigations revealed multidrug-resistant Mycobacterium tuberculosis as the etiological agent. We reviewed cases of anterior tuberculous scleritis published in the literature, with regards to clinical features, microbiological investigations, treatment, and outcomes. Treatment includes standard antitubercular therapy, with or without systemic corticosteroids. Poor response to treatment is seen either due to delayed diagnosis or drug resistance, and the significance of the same is highlighted in our case.

CONCLUSION

Diagnosis of tuberculous scleritis is a challenge. Therapeutic failure must alert the clinician for drug resistance which is diagnosed early, can prevent the devastating outcomes.
