BACKGROUND Corneal renewal and repair are mediated by stem cells of the limbus, the narrow zone between the cornea and the bulbar conjunctiva. Ocular burns may destroy the limbus, causing limbal stem-cell deficiency. We investigated the long-term clinical results of cell therapy in patients with burn-related corneal destruction associated with limbal(More)
AIM Limbal cultures restore the corneal epithelium in patients with ocular burns. We investigated the biological parameters instrumental for their clinical success. METHODS We report a long-term multicenter prospective study on 152 patients carrying corneal destruction due to severe ocular burns, treated with autologous limbal cells cultured on fibrin and(More)
PURPOSE To describe a case of Nocardia keratitis resistant to 2% amikacin, with a toxic-allergic reaction to fortified topical 5% amikacin, and recurrence of the infection with topical corticosteroids. METHODS Nocardia was diagnosed from a smear and positive culture and identified as Nocardia asteroides by gas chromatography and quantitative fatty acid(More)
A 32-year-old man with keratoconus developed corneal melting 5 days after riboflavin/ultraviolet-A corneal collagen crosslinking (CXL). Corneal scraping was positive for Acanthamoeba. The patient was unaware that he was wearing a bandage contact lens and repeatedly rinsed his face and eyelids with tap water. Because of corneal perforation, a large(More)
Acanthamoeba keratitis (AK) is a corneal disease caused by members of a genus of free-living amoebae and is associated predominantly with contact lens (CL) use. This study reports 16 cases of culture-proven AK diagnosed in northern Italy. Genotype identification was carried out with a PCR assay based on sequence analysis of the 18S rRNA gene, and(More)
AIMS To report the clinical and diagnostic findings of a patient with Acanthamoeba keratitis resistant to both polyhexamethylene biguanide (PHMB)-hexamidine and chlorhexidine-hexamidine treatment. METHODS Slit-lamp biomicroscopy, corneal cell scraping and histopathology were performed on a 39-year-old woman presenting with corneal ulcer in her left eye.(More)
An increase in the incidence of fungal infections has highlighted the need for rapid and precise detection and identification methods in clinical mycology. This report describes the data obtained on corneal samples from 24 patients with suspected keratomycosis using a conventional cultural approach in parallel with PCR amplification and sequencing of the(More)
PURPOSE To report a case of bilateral Acanthamoeba keratitis with late, atypical recurrence after penetrating keratoplasty a chaud. METHODS A 23-year-old contact lens wearer was treated for bilateral Acanthamoeba keratitis and underwent penetrating keratoplasty in the right eye for descemetocele with impending risk of perforation. The postoperative course(More)
AIMS To evaluate the clinical findings and visual outcomes of deep anterior lamellar keratoplasty (DALK) using an original manual dissection technique. METHODS 288 eyes (268 patients) with corneal pathologies without endothelial involvement were treated by DALK using an original manual dissection technique guided by a calibrated knife incision based on(More)
