  • Title: Relationship between sympathetic ophthalmia, phacoanaphylatic endophthalmitis, and Vogt-Koyanagi-Harada disease.
    Author: Chan CC.
    Journal: Ophthalmology; 1988 May; 95(5):619-24. PubMed ID: 3050697.
    Abstract:
    The more than coincidental occurrence of phacoanaphylatic endophthalmitis (PE) in sympathetic ophthalmia, and the similarity of the dissimilarity between Vogt-Koyanagi-Harada (VKH) disease and sympathetic ophthalmia have been well described both clinically and histopathologically. The etiology and pathogenesis of these three diseases are still not fully understood. Identifying and distinctive characteristics among them include the history of ocular trauma in sympathetic ophthalmia, rupture of the lens capsule in phacoanaphylatic endophthalmitis, and involvement of the skin, ear, and central nervous system in VKH disease. A T-cell-mediated immune reaction to ocular antigens seems to play a major role in sympathetic ophthalmia and VKH disease. A B-cell-related Arthus reaction to lens antigen seems to be the principle mechanism of PE. Thus, these three diseases may represent a spectrum of uveitis. At one end is the delayed-type hypersensitivity disease of sympathetic ophthalmia, whereas at the opposite end is the immune complex disease of PE, with VKH disease in the middle of this uveitic spectrum.
