We encountered six (0.2%) cases of endophthalmitis resulting from
contaminated donor corneas between January 1983 and July 1990 following a
total of 3000 consecutive penetrating keratoplasties. Causative organisms
in the three cases of fungal endophthalmitis were Torulopsis glabrata,
Candida albicans, and Aspergillus flavus; the three cases of bacterial
endophthalmitis were due to Klebsiella pneumoniae, Staphylococcus aureus,
and Enterococcus faecalis. All organisms were resistant to gentamicin in
the preservation media. A significantly higher incidence of endophthalmitis
was noted in patients receiving corneas from a Sri Lankan eye bank (1.25%)
than in those receiving US eye bank tissue (0.14%). Donor rim cultures are
important to identify those patients at increased risk of developing
endophthalmitis, enabling earlier diagnosis and more specific treatment
should endophthalmitis occur.
