A 3-year-old boy underwent secondary implantation of an iris supported intraocular lens following extraction of a unilateral congenital cataract. Eight months later, he developed a bilateral plastic uveitis which, in spite of intensive medical treatment, resulted in NPL (no perception of light) in the implanted eye and 2/60 vision in the fellow eye. Sympathetic ophthalmia possibly played a role in the pathogenesis of the uveitis.
