Presumed stromal graft rejection after automated lamellar therapeutic keratoplasty: case report

PURPOSE: To describe the development of presumed immune-mediated stromal rejection after automated lamellar therapeutic keratoplasty (ALTK) and its reversal after initiation of intensive topical corticosteroid therapy. METHODS: Observational case report. RESULTS: Stromal edema localized in the graft developed 42 days after ALTK for Avellino corneal dystrophy in a 65-year-old man. After one week of intensive topical corticosteroids, complete reversal of graft edema occurred, with full recovery of visual function. CONCLUSION: The clinical appearance and response to therapy in this case supported the diagnosis of immune-mediated stromal rejection. Ophthalmologists should be aware that stromal rejection may occur in lamellar corneal grafts

Intracorneal bacterial colonization in a crystalline pattern

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.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47391/1/417_2005_Article_BF02143065.pd
