Purpose: To describe the frequency, risk factors, management, and outcome of eyes with tubercular serpiginous-like choroiditis showing continued progression following initiation of antituberculosis treatment.
Design: Retrospective, comparative, interventional case series.
Patient population: One hundred ten patients of serpiginous-like choroiditis with 1) complete records, 2) tuberculin skin test, 3) active lesions in at least 1 eye, and 4) minimum 18 months follow-up.
Intervention: Based on the positivity of tuberculin skin test, the patients were categorized in Group A (84 patients with positive tuberculin test) and Group B (26 patients with negative tuberculin test). Of the 84 patients in Group A, 19 received systemic corticosteroids while 65 also received 4-drug antituberculosis treatment in addition. All patients in Group B received corticosteroids. Patients with continued progression received an increased dose of corticosteroids with or without immunosuppressive agents.
Main outcome measure: Development of continued progression.
Results: There were 61 men and 23 women in Group A and 19 men and 7 women in Group B. Continued progression was observed in 12 patients (14.28%) in Group A and none in Group B (P = .04). Of the 12 patients in Group A showing progression, 11 (16.9%) were receiving antituberculosis treatment and corticosteroids. The lesions responded in all eyes, and final visual acuity of 20/40 or better could be achieved in 10 eyes (75%).
Conclusion: Continued progression of choroiditis lesions occurs in 14% of patients after initiating antituberculosis treatment in tubercular serpiginous-like choroiditis. Increased immunosuppression with continuation of antituberculosis treatment resulted in good outcome.
