# Fusarium Corneal Abscess: A Case Report

## TL;DR

This case report describes a rare Fusarium corneal abscess in a young, healthy individual, highlighting the importance of considering this infection even without risk factors.

## Contribution

The novelty is the documentation of Fusarium infection in an immunocompetent patient with a healthy cornea.

## Key findings

- Fusarium was diagnosed through clinical and biological evidence in an otherwise healthy patient.
- The infection occurred without typical risk factors, suggesting new insights into Fusarium pathogenesis.
- The case emphasizes the need for thorough evaluation in corneal infections despite the absence of risk factors.

## Abstract

Fusarium is a cosmopolitan fungus that can cause serious eye infections that threaten the functional prognosis of patients. Fusarium keratitis is the most serious, and its management remains laborious, requiring a multitude of therapeutic options ranging from medical treatment to surgical treatment. We report on the case of a 20-year-old patient who was diagnosed with a corneal mycotic Fusarium abscess grafted onto a healthy cornea. The diagnosis is made on a bundle of clinical and especially biological arguments by the demonstration of Fusarium on two occasions by direct examination and culture. The diagnosis must be considered in the presence of one or more risk factors; however, it must be considered even in their absence because, according to this case, Fusarium can graft onto a healthy cornea in immunocompetent individuals, based on clinical and biological data.
