    Summary

    A rare case of bacterial colonization occurred 22 months post-penetrating keratoplasty in a 78-year-old woman. This involved fern-like stromal opacities caused by gram-positive cocci with minimal inflammation.

    Area of Science:

    • Ophthalmology
    • Microbiology

    Background:

    • Penetrating keratoplasty (corneal transplant) is a common procedure to restore vision.
    • Late complications can occur, necessitating ongoing patient monitoring.

    Observation:

    • A 78-year-old woman presented with visual disturbances 22 months after a corneal transplant.
    • Slit-lamp examination showed unique, fern-like opacities within the corneal stroma.

    Findings:

    • Histopathology revealed large intrastromal aggregates of gram-positive cocci.
    • The bacterial colonization elicited minimal host inflammatory response.

    Implications:

    • This case highlights a rare late complication of penetrating keratoplasty.
    • Intrastromal bacterial colonization can present with subtle, non-specific signs.
