Fungal corneal infections—also known as fungal keratitis—are serious eye conditions that can lead to permanent vision loss if not treated promptly. These infections occur when fungi invade the cornea, often following an injury or exposure to contaminated material. In Karachi’s warm, humid climate, fungal corneal infections are more common, particularly among individuals who work outdoors or use contact lenses.
How Fungal Corneal Infections Develop
Fungal keratitis is typically caused by two main types of fungi: filamentous fungi, often linked to plant matter injuries, and yeast-like fungi, which may affect people with chronic eye conditions. Common causes and risk factors include:
- Eye injuries involving soil or plant material
- Contact lens misuse or poor hygiene
- Long-term use of steroid eye drops
- Pre-existing corneal disease
- Exposure to contaminated water or environment
Even a small scratch on the cornea can allow fungi to enter and multiply.
Symptoms You Should Never Ignore
Fungal corneal infections may begin subtly but can worsen quickly. Warning signs include:
- Severe eye pain
- Redness and irritation
- Blurry or decreased vision
- Light sensitivity
- Thick discharge
- A white or gray spot on the cornea
Any of these symptoms require immediate examination by an eye specialist.
How Fungal Keratitis Is Treated
Unlike bacterial infections, fungal keratitis usually requires longer and more intensive treatment. Options include:
1. Antifungal eye drops
Medications such as natamycin or voriconazole are used to stop the infection.
2. Oral or injectable antifungal medications
Needed for deeper or more severe infections.
3. Debridement
Gently removing infected tissue to help medication penetrate better.
4. Corneal transplant (keratoplasty)
Required in advanced cases where the cornea has been severely damaged.
Early diagnosis is critical—delayed treatment increases the likelihood of scarring or vision loss.
