Objectives: Fungal keratitis is rare in France, but could be a severe sight-threatening condition. Here, we aimed to describe the epidemiology of fungal keratitis in Réunion Island.
Methods: In a retrospective study, we analyzed 13 culture-proven keratitis episodes, occurred between January 2013 and July 2017 in the ophthalmology ward of a University Hospital, Saint-Pierre. Twelve isolates were genotyped and antifungal susceptibility testing was performed.
Results: Corneal abrasion caused by vegetable matter was the main predisposing factor. Stromal infiltration was observed in 12 patients. Six patients did not response to medical treatment, requiring surgical care, including two enucleations surgery. Fusarium solani (n = 6) and Fusarium dimerum (n = 4) were the main fungal species involved in fungal keratitis. Clinical failures were more prevalent with F. solani infections. The lowest minimal inhibitory concentrations for Fusarium sp. were observed with voriconazole and amphotericin B.
Conclusion: In Reunion Island, the epidemiology of fungal keratitis is characterized by the predominance of Fusarium species, potentially involved in visual loss. This pattern is consistent with the epidemiology usually observed in tropical areas.

Background: We report a rare case of fungal keratitis caused by , a filamentous fungus that is widely distributed in soil and graminaceous plants.
Case Presentation: A 40-year-old Mongoloid male patient came to our outpatient clinic with painful swelling of the left eye and redness, after being cut by a tree branch 1 week prior. After examination, the patient was diagnosed with a corneal ulcer of the left eye, and was given levofloxacin eye drops and levofloxacin ophthalmic gel.

The treatment of fungal keratitis(FK) remains challenging due to delayed fungal detection and the limited effectiveness of antifungal drugs. Fungal infection can activate both innate and adaptive immune responses in the cornea. Fungi stimulate the production of oxidative stress-related biomarkers and mediate the infiltration of neutrophils, macrophages, and T cells.

Introduction: Fungal keratitis is a leading cause of corneal blindness, with current antifungal treatments having limited efficacy. One promising treatment modality is Rose Bengal (RB) photodynamic antimicrobial therapy (PDAT) that has shown mixed success against fungal keratitis. Therefore, there is a need to explore the antimicrobial efficacy of other green-light activated photosensitizers that have deep penetration in the cornea to combat the deep fungal infections, such as Erythrosin B (EB) and Eosin Y (EY).

Background: Acanthamoeba keratitis (AK) is the most challenging corneal infection to treat, with conventional therapies often proving ineffective. While photoactivated chromophore for keratitis-corneal cross-linking (PACK-CXL) with riboflavin/UV-A has shown success in treating bacterial and fungal keratitis, and PACK-CXL with rose bengal/green light has demonstrated promise in fungal keratitis, neither approach has been shown to effectively eradicate AK. This case study explores a novel combined same-session treatment approach using both riboflavin/UV-A and rose bengal/green light in a single procedure.

This is a prospective non-comparative experimental study aimed to investigate the presence of microsporidia in household pipe water of microsporidial keratitis (MK) patients and to describe the patients' characteristics and behavioral risk factors. This study was conducted at Walailak University Hospital, Thailand, from July 2022 to February 2024. Patients diagnosed with MK were surveyed using a questionnaire to assess personal behaviors and source of household water.
