Yeast keratitis is a type of fungal keratitis caused by yeast-like organisms, most commonly Candida albicans. Unlike filamentous fungi, yeast infections typically occur in eyes already compromised by chronic surface disease.
read more about yeast keratitis ...The primary risk factors for yeast keratitis include the long-term use of corticosteroid eye drops, chronic dry eye, or a history of corneal surgery (like a transplant).
Symptoms include severe pain, redness, blurred vision, and light sensitivity. Clinically, a "yeast" infection often appears as a localized, creamy-white or "button-like" ulcer on the cornea.
Because it can look like a bacterial infection, a corneal scraping is required. The sample is cultured on specialized media (like Sabouraud agar) and viewed under a microscope.
Yeast keratitis is treated with topical antifungal medications such as Amphotericin B or Natamycin. Treatment is often prolonged, lasting weeks or months.
