Allogeneic cultivated limbal epithelial transplantation, followed by PK when needed, can successfully restore the ocular surface and improve vision in patients with corneal blindness due to bilateral LSCD.

BackgroundGiven the rise in cases of fungal keratitis in recent years, this study was performed to better elucidate the microbiological profile, risk factors, and surgical intervention rates of fungal keratitis at a tertiary referral center in the Southeastern USA.FindingsThis is a retrospective case series of fungal keratitis infections treated at Duke University Eye Center from January 1, 1998, to October 6, 2008. Of the 4651 culture-proven corneal ulcers identified, 63 (1.4 %) were positive for fungal keratitis with a total of 69 fungal organisms isolated. The majority of isolates were filamentous species (44 of 69, 64 %), and the most commonly isolated organism was Curvularia (11 of 69, 16 %). Bacterial coinfections were found in 24 of the 63 cases (38 %). The most commonly associated risk factors were contact lens wear (n = 15, 24 %) and prior penetrating keratoplasty (PKP) (n = 15, 24 %). Twenty-three cases (37 %) required surgical intervention. The rate of surgical intervention was highest in patients with prior PKP (7/15, 47 %).ConclusionsIn this study, the leading risk factors for fungal keratitis were contact lens wear and prior PKP. Filamentous species were the most common causative pathogens. A relatively high rate of mixed bacterial-fungal infections was found. Patients with prior PKP were more likely to require surgery than patients without history of keratoplasties.
