Background & Objectives: Fungal infections of the eye are rampant in tropical regions and are responsible for significant ocular morbidity and blindness. Prompt and specific identification of fungi is important in order to define clinical treatment. However, in most cases conventional culture identification can be considered to be time consuming, of low sensitivity and not without errors. The a...

Purpose To investigate the expression and roles of type I and II interferons (IFNs) in fungal keratitis, as well as the therapeutic effects of tacrolimus (FK506) and voriconazole on this condition. Methods The mRNA and protein expression levels of type I (IFN-α/β) and II (IFN-γ) IFNs, as well as of related downstream inflammatory cytokines (interleukin (IL)-1α, IL-6, IL-12, and IL-17), were d...

Purpose. To evaluate the efficacy of a combination of intrastromal and intracameral injections of amphotericin B in the treatment of severe recalcitrant fungal keratitis. Methods. Patients with severe fungal keratitis who were resistant to conventional antifungal medical treatments and needed potential surgical intervention were recruited at the First Affiliated Hospital of Fujian Medical Unive...

To observe and analyze the curative effects of the treatment of riboflavin combined with 440 nm blue-light corneal cross-linking (CXL) treatment for fungal keratitis via a rabbit model experiment. A model of rabbit fungal keratitis was used through anterior stromal injection in which 24 rabbits were randomly divided into blank control, 360 nm group, and 440 nm group. Both groups underwent CXL t...

Purpose. To evaluate effects of lamellar keratectomy and intrastromal injection of 0.2% fluconazole (LKIIF) on fungal keratitis. Methods. Data for 54 eyes of consecutive patients with fungal keratitis treated with LKIIF were retrospectively analyzed. The lesions in these eyes did not heal or were aggravated after antifungal chemotherapy for 7 days. The maximum lesion diameters were ≤5 mm and ma...

Fusarium is the major causative agent of fungal infections leading to corneal ulcer (keratitis) in Southern India and other tropical countries. Keratitis caused by Fusarium is a difficult disease to treat unless antifungal therapy is initiated during the early stages of infection. In this study tear proteins were prepared from keratitis patients classified based on the duration of infection. Am...

AIMS To investigate whether cryopreserved donor cornea could be used for therapeutic penetrating keratoplasty (PKP) to eradicate the infection, obviate complications, and preserve anatomical integrity in severe fungal keratitis. METHODS In this retrospective, consecutive case series, 45 eyes of 45 patients with severe fungal keratitis, which exhibited anterior chamber collapse, corneal perfor...

The authors describe a case of fungal keratitis that the in vivo confocal microscopy helped in the diagnosis and follow-up. Confocal microscopy was done in a patient's ulcer that did not improve with several topical medicines. Corneal scrapings were obtained and culture results were without conclusion. We observed hyphae and infectious collections on confocal microscopy. New corneal culture sho...

Medical treatment failure necessitated surgery in nine cases of fungal keratitis. Therapeutic surgery eliminated fungal infection in seven cases, and useful vision was retained in five out of six penetrating keratoplasties. In three cases Natamycin (Pimaricin) therapy rendered fungi non-viable, but two were demonstrable by histopathology. These results suggest that antifungal treatment should b...
