The current monkeypox virus (MPXV) outbreak, raging since May 2022, is the largest ever observed on a world-wide scale. Despite previously being endemic in west and central Africa with a mortality rate of up to 10%, it remained a neglected tropical disease. Along with other recent pandemics gaining much attention, this MPXV outbreak has provided an opportunity to improve our understanding of its physiopathology and better define management strategies, particularly in patients with more serious disease. From the ophthalmologist's perspective, eyelid involvement and conjunctivitis or keratoconjunctivitis are frequently observed and may precede systemic signs or even remain the major site of involvement. While the course of MPXV keratoconjunctivitis is most often favorable, severe cases pose a functional threat, in particular for immunocompromised patients. This review provides an overview of MPXV pathophysiology, diagnosis and treatment, as well as considerations for prevention of transmission. During such an epidemic, the ophthalmologist can be the first to diagnose MPXV, treat the ocular involvement, and set up adequate preventative measures in collaboration with infectious disease specialists., (Copyright © 2023 Elsevier Masson SAS.

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., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)
