Two cases of pseudoretinitis pigmentosa are reported, in which histopathologic examinations revealed selective loss of much of the photoreceptive layer as early as 12 days and 37 days, respectively, after the injury. It is suggested that the loss of the photoreceptors is secondary to release of lytic enzymes from the pigment epithelium.
