Fungal keratitis is a serious corneal infection often linked to plant material injury, contact lenses, or hot, humid climates. Treatment is challenging and usually prolonged.
Medical therapy
Diagnosis relies on careful examination and laboratory tests. Specific antifungal medicines are needed because standard antibiotics are ineffective.
- Topical antifungal drops such as natamycin or voriconazole
- Systemic tablets or injections in deeper or more severe infections
- Frequent dosing and long courses, often for weeks
- Careful monitoring for toxicity and response
Surgical options
Some cases do not respond fully to medicines alone. Surgery may be needed to control infection and restore structure.
- Debridement of infected tissue to improve drug penetration
- Therapeutic corneal transplantation for deep or non-healing ulcers
- Management of raised pressure or perforation if they occur
- Long-term follow-up to watch for recurrence and scarring
