Overview
A chronic, recurrent, bilateral corneal disease of unknown aetiology characterised by coarse, elevated, grey-white epithelial deposits that stain poorly with fluorescein but well with rose bengal. The conjunctiva is white and quiet. No limbal injection, no associated blepharitis, no corneal infiltrate. Aetiology is uncertain — viral or immune-mediated mechanisms are proposed. Responds to topical steroids but recurs on cessation.
