title: Immunopathology of sympathetic ophthalmia.
abstract: The long held notion that sympathetic ophthalmia represents an autoimmune reaction to uveal pigment is no longer tenable. Pigmentation influences the histopathologic picture of sympathetic ophthalmia but no evidence supports the role of uveal pigment as inciting antigen. Several recent studies have confirmed our initial report of the participation of cellular hypersensitivity to ocular tissues in the pathogenesis of this disease. Both clinical and experimental studies implicate retinal tissue as being more immunogenic than uveal antigens. The recent histopathologic observation that eosinophils concentrate near the choriocapillaris suggests that outer retina and retinal pigment epithelium should not be overlooked as a potential source of the stimulating antigen in sympathetic ophthalmia.
