Macular coccidioidomycosis
Summary
Ocular coccidioidomycosis, a fungal infection, presented as a macular lesion in a Canadian patient. Prompt treatment led to rapid healing, suggesting this is the first reported case in Canada.
Area of Science:
- Ophthalmology
- Mycology
- Infectious Diseases
Background:
- Macular lesions can have diverse etiologies, necessitating accurate diagnosis.
- Fungal infections, such as coccidioidomycosis, can manifest in ocular tissues.
- Distinguishing ocular coccidioidomycosis from other macular diseases is crucial for appropriate management.
Observation:
- A 26-year-old woman presented with an enlarging, dense macular lesion in her right eye.
- Funduscopic and angiographic findings were atypical for macular histoplasmosis.
- A concurrent diagnosis of a pulmonary coccidioidomycotic granuloma was established.
Findings:
- The patient received treatment with amphotericin B for the pulmonary infection.
- The macular lesion showed cicatricial changes within one month of treatment initiation.
- This case represents presumed ocular coccidioidomycosis, the first reported instance in Canada.
Implications:
- This case highlights the potential for coccidioidomycosis to present with unusual ocular manifestations.
- Early diagnosis and systemic antifungal treatment can lead to favorable visual outcomes.
- Increased awareness is needed among clinicians in non-endemic regions for diagnosing ocular fungal infections.
