Anatomy of passive arthus reaction in the cornea. A preliminary communication.

Corneal changes in passive Arthus reaction are essentially the same as that reported to occur in active Arthus reaction and consist of accumulation of polymorphonuclear leucocytes around the deposits of immune complexes, release of lysosomes and fragmentation and dissolution of collagen fibrils. In addition, degenerative changes were found in the corneal endothelium and Descemet's membrane.
