Question

Confoacal mocroscopy is useful in fungal keratitis

Answer 1

Fungal keratitis is much less common than bacterial keratitis in the United States. Risk factors for developing fungal keratitis include trauma with vegetable matter, immunosuppression (especially with topical corticosteroids), and contact lens wear. The classic appearance of fungal keratitis is a gray-white, dry-appearing infiltrate with feathery borders. However, these findings are not always present, nor are they pathognomonic for the disease, so corneal cultures, smears, and scrapings are often utilized to aid in the diagnosis.
