What is Orbital Zygomycosis?
Orbital zygomycosis is a serious fungal infection affecting the eye socket (orbit), caused by fungi from the order Mucorales. It often starts as a sinus infection and can rapidly spread to the orbit, leading to tissue damage and vision loss if untreated.
What Causes Orbital Zygomycosis?
- Fungal Invasion – The fungi spread from nearby infected sinuses into the orbit.
- Immunocompromised Conditions – Common in individuals with diabetes, weakened immune systems, or those on corticosteroid therapy.
- Trauma or Surgery – May provide an entry point for fungal spores.
What Are the Symptoms of Orbital Zygomycosis?
- Eye pain and swelling around the orbit
- Redness and inflammation of the eyelids and surrounding tissues
- Proptosis (bulging of the eye)
- Vision changes or loss
- Fever
- Nasal congestion or sinus symptoms if infection started there
How is Orbital Zygomycosis Diagnosed?
- Clinical Examination – Assessing eye symptoms and sinus involvement.
- Imaging Tests – CT scan or MRI to detect infection spread and tissue involvement.
- Microbiological Tests – Tissue biopsy and culture to identify fungal species.
- Histopathology – Examination of tissue samples showing characteristic fungal invasion.
How is Orbital Zygomycosis Treated?
- Antifungal Therapy – Prompt administration of intravenous amphotericin B or other antifungals.
- Surgical Debridement – Removal of infected tissue may be required to control infection.
- Management of Underlying Conditions – Optimizing blood sugar levels and immune status.
- Supportive Care – Monitoring and supportive treatment to preserve vision and prevent complications.
Prognosis of Orbital Zygomycosis
Orbital zygomycosis can progress rapidly and cause permanent vision loss or spread to the brain if not treated early. Early diagnosis and aggressive treatment improve outcomes.
Can Orbital Zygomycosis Be Prevented?
- Controlling diabetes and immune system health
- Avoiding exposure to environments with high fungal spore loads
- Prompt treatment of sinus infections, especially in at-risk individuals
