Did you know that sleeping in your contact lenses, over-wearing your contact lens, and not cleaning/disinfecting your contact lenses properly can cause a corneal infiltrate?
Bacterial exotoxins are responsible for whitish/gray anterior stromal infiltrates in the cornea. They are usually round, well defined, and small, ranging in size from 0.1mm to 2.0mm. There are often mild symptoms of discomfort, foreign body sensation, eye redness, and tearing, but usually no vision loss.
Corneal infiltrates are treated with antibiotics and anti-inflammatory drops. Changing to disposable contact lenses or discontinuing lens wear are recommended.
