Reactive cellular membrane on a glass fragment after two years in the anterior chamber.

An optically clear membrane composed of a continuous proteinaceous film and sessile cells of macrophage origin was present on the surface of a glass fragment removed from the anterior chamber of the eye of a nine-year-old boy almost two years after a perforating corneal injury. This finding indirectly contributes to the understanding of membranes formed by the inner eye during adaptation to an intraocular lens implant.
