Summary
Two cases of unilateral corneal ulcers caused by Acanthamoeba were reported in patients without contact lens wear. Diagnosis was confirmed via Giemsa stain and corneal scraping cultures, highlighting non-contact lens-related Acanthamoeba keratitis.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Acanthamoeba keratitis (AK) is a serious eye infection, often associated with contact lens wear.
- Non-contact lens-related AK cases are less common but pose diagnostic challenges.
Observation:
- Two patients presented with unilateral corneal ulcers.
- Neither patient reported any history of contact lens use.
Findings:
- Diagnosis of Acanthamoeba infection was confirmed using Giemsa staining of corneal scrapings.
- Microbiological cultures of corneal scrapings also supported the diagnosis of Acanthamoeba keratitis.
Implications:
- These cases underscore the importance of considering Acanthamoeba keratitis in non-contact lens wearers.
- Prompt diagnosis through Giemsa stain and culture is crucial for effective management of this sight-threatening infection.
