Intravitreal methotrexate in the management of presumed tuberculous serpiginous-like choroiditis.

PURPOSE: To report on the use of intravitreal methotrexate (IVT MTX) as part of treatment of presumed tuberculous serpiginous-like choroiditis progressing despite the use of tuberculostatics.

METHODS

Case series of patients suffering from serpiginous-like choroiditis with positive tuberculin skin test who received IVT injections of MTX as part of treatment. Ocular disease was active despite the use of systemic tuberculostatic (isoniazid, rifampicin, pyrazinamide, and ethambutol), and choroidal lesions showed signs of progression. A single injection of IVT MTX (400 μg/0.1 mL) was administered in the eye with macular-threatening features. Change in visual acuity, appearance of the lesion, and staining patterns on angiography were among the main outcome measurements.

RESULTS

Three eyes from two patients were included. Both cases presented bilateral involvement with mild vitritis. In all three eyes, choroidal lesions healed within the first month after an IVT MTX injection with visual acuity improvement in two. No adverse reaction was related to the medication or to the procedure. Patients were followed for a mean of 13.5 months after being injected.

CONCLUSION

The use of IVT MTX seems effective in the management of the inflammatory component of tuberculous serpiginous-like choroiditis, whereas systemic tuberculostatics are aimed at controlling the infectious one.
