Corneal Cross-linking as an Adjuvant Therapy in the Management of Recalcitrant Deep Stromal Fungal Keratitis: A Randomized Trial - 08/06/15
Abstract |
Purpose |
To assess the efficacy of corneal cross-linking (CXL) as an adjuvant to appropriate antifungal therapy in nonresolving deep stromal fungal keratitis.
Design |
Randomized clinical trial.
Methods |
Eyes with culture-positive deep stromal fungal keratitis not responding to appropriate medical therapy for a period of 2 weeks were randomized to receive either adjuvant CXL or no additional treatment. Antifungal medical therapy was continued in both groups. The prespecified primary outcome was treatment failure at 6 weeks after enrollment, defined as perforation and/or increase in ulcer size by ≥2 mm.
Results |
The trial was stopped before full enrollment because of a marked difference in the rate of perforation between the 2 groups. Of the 13 cases enrolled in the study, 6 were randomized to the CXL group and 7 to the non-CXL group. Five eyes in the CXL group and 3 eyes in the non-CXL group experienced treatment failure by 6 weeks (P = .56). In a secondary analysis, the CXL group experienced more perforations than the non-CXL group (4 vs 0, respectively; P = .02).
Conclusion |
CXL used as adjuvant therapy for recalcitrant deep stromal fungal keratitis did not improve outcomes.
