Objective:

To report the first documented case of successful compassionate use of topical cidofovir 0.5% in severe Clade Ib mpox keratitis unresponsive to trifluridine.

Approach:
    Key Findings:
    • The patient had severe keratitis with persistent epithelial defects and stromal haze despite treatment with trifluridine.
    • Topical cidofovir was administered after trifluridine failed to improve the condition.
    Interpretation:

    The case highlights the potential role of cidofovir in treating mpox keratitis when standard treatments are ineffective.

    Limitations:
    • This is a single case report, limiting generalizability.
    • No long-term follow-up data on the efficacy and safety of cidofovir in this context are provided.
    Conclusion:

    Topical cidofovir may be a viable treatment option for severe mpox keratitis, warranting further investigation.
