    Schematic of the corneal adhesion complexes: anchoring filaments extend through the basement membrane and emerge as anchoring fibrils in the stromal side, forming an intertwining network in the anterior 2μm stroma [65]. These anchoring fibrils insert into anchoring plaques. All these factors are termed the “adhesion complex” [65]. Type VII collagen is the anchoring fibril collagen, its domain being in the lamina densa and in the anchoring plaques .

    Time lapse of a contact lens wearer presenting with corneal erosion. The patient presented complaining of difficulty removing her contact lens. A: Central corneal erosion immediately after lens removal; B: Appearance after 3h; C: appearance of erosion after 7h suggests a healed erosion with disturbed epithelial staining overlying this.

    Solution induced corneal staining, also described as punctate staining, affects the superficial layers of the epithelium and differ to corneal erosions.
