What Is a Corneal Ulcer?
2. What Causes Corneal Ulcers?
Corneal ulcers are most commonly caused by infections. Bacterial infections are a common cause of corneal ulcers, as are viral infections. Viral infections such as varicella virus and herpes simplex virus can also cause the common eye condition. Fungal infections are less common but can occur after the eye is injured by a twig or other natural material. Parasitic infections are also uncommon but can still cause corneal ulcers.
To protect your eyes from these things, wear eye protection when working on projects that involve wood or other materials. You should also avoid opening your eyes under the water when swimming in ponds or lakes.
