Corneal ulcer risk factors

People with poor eye hygiene and contact lens abusers (e.g. those who wear contact lenses overnight) are at an increased risk of developing corneal ulcers. Corneal ulcers are a common condition in humans, particularly those living in the tropics and in agrarian societies. In developing countries, children afflicted by vitamin A deficiency are at a high risk for corneal ulcer and may become blind in both eyes, which may persist lifelong if not treated.
