title: Intracorneal bacterial colonization in a crystalline pattern.
abstract: We report the case of a 78-year-old woman who developed an intrastromal bacterial colonization 22 months after penetrating keratoplasty. Slit-lamp examination revealed discrete, finely branched, fernlike stromal opacities, which were histopathologically found to be large intrastromal aggregates of gram-positive cocci with almost no inflammatory cell response.
