Keratitis due to Mycobacterium chelonei

Area of Science:

• Ophthalmology
• Microbiology
• Pathology

Background:

• Ulcerative keratitis presents a significant challenge in ocular surface disease.
• Prompt and accurate diagnosis is crucial for effective treatment and visual preservation.

Observation:

• A patient presented with ulcerative keratitis requiring comprehensive ophthalmological evaluation.
• Bacteriological and histopathological analyses were performed to identify the causative agent.

Findings:

• Mycobacterium chelonei was consistently isolated from the corneal lesion.
• The bacterium was detected both pre- and post-operatively, indicating treatment resistance.

Implications:

• This case highlights the diagnostic and therapeutic challenges posed by Mycobacterium chelonei in ulcerative keratitis.
• Understanding the persistence of this pathogen is vital for developing targeted treatment strategies.
