Presumed late diffuse lamellar keratitis progressing to interface fluid syndrome.

We report an unusual case of presumed late-onset unilateral diffuse lamellar keratitis of uncertain etiology in a 23-year-old man who presented with elevated intraocular pressure following uneventful laser in situ keratomileusis (LASIK). After treatment with topical corticosteroid therapy, the condition progressed to interface fluid syndrome. Isolated pockets of fluid were clearly demonstrated at the level of the LASIK flap interface on slitlamp biomicroscopy and in Pentacam Scheimpflug images.
