The clinical picture of a 12 year-old boy with Reiter's syndrome, manifested by conjunctivitis, keratitis, polyarthritis and urethritis, is presented and compared with the other 26 boys and girls with this syndrome that have been reported elsewhere. Light microscopy and inmunofluorescence studies of synovial membrane showed nonspecific changes. However, with the electron-microscope two types of cellular inclusions were seen in both, synovial cells and macrophages. Such changes were similar to those described in adults with Reiter's syndrome.

Clinical picture and course of eye involvement were studied in 254 patients with Reiter's disease. Altogether 130 patients suffered from conjunctivitis of varying severity, 23 from keratitis, 21 from episcleritis, 20 from uveitis, 2 from detachment of the retina, and 5 from secondary glaucoma. Chlamydia were detected in one third of conjunctivitis patients in scrapings off the conjunctiva. The eyes may be accidentally infected by agents from the urogenital organs if the patient does not observe the hygienic rules. Uveitis developed as a rule after a prolonged course of Reiter's disease. They were resistant to antichlamydial therapy because of autoimmune factors that underlay the condition pathogenesis. Deposits of immune complexes on antigens of ocular vascular coating were detected with the use of monospecific antiglobulin sera in 7 of 10 patients with active uveitis symptoms. The risk of Reiter's disease development in HLA B27 carriers is 27.17 times higher than the mean incidence of this disease in the population. HLA A9 and B40 antigen combinations occurred 7 times more often in uveitis patients than in reference subjects, A1 and B27 combinations were 4-5 times more incident.

The clinical, microbiologic, and cytologic features of the guinea pig model of keratoconjunctivitis with enterobacteria, Salmonella typhimurium were elucidated. Guinea pig eyes were instilled with S. typhimurium and the eyes were studied by biomicroscopy, culture, cytology, pathology, and electron microscopy. All animals developed moderate to severe conjunctivitis that was present in 18% of the animals on day 1. It became more intense, appearing in all of the eyes on day 10 and disappeared before day 30. The cultures for S. typhimurium were almost all positive on days 1 and 2, declined steadily to 10% on day 10, and were negative after that. A coarse, epithelial punctate keratitis was present in more than 90% of the infected eyes at some time during the experiment. The keratitis had a biphasic clinical course. The first peak correlated with the maximum culture results, but during the second peak only 10% of the cultures were positive. Electron microscopy of the cornea showed the S. typhimurium at the epithelial surface within surface epithelial cells during the early phases of infection. The later phase keratitis, with negative culture results, resembles the keratitis of Reiter's syndrome.

A distinctive keratitis occurs commonly in Reiter's syndrome. In three patients with Reiter's keratitis, two demonstrated the typical features of prodromal conjunctivitis, subepithelial and anterior stromal infiltrates, ragged epithelial erosions, and spontaneous resolution. A third case of rare, severe keratitis in addition had an associated finding of disciform keratitis. To our knowledge, this last finding has not previously been reported. Chlamydia has been implicated as an etiologic agent in Reiter's syndrome. Giemsa's stain of corneal epithelial cells in one of our patients disclosed intracytoplasmic inclusions that resembled those seen in Chlamydia-caused conjunctivitis. The patient also exhibited a rising serum titer to Chlamydia antigen.

We studied characteristics of ocular inflammation associated with Yersinia infection in 23 patients. After an acute onset with fever, diarrhea, and abdominal pain, 22 patients developed arthritis, 11 patients developed myalgia, 11 patients developed Reiter's syndrome, 17 patients developed acute anterior uveitis, and nine patients developed conjunctivitis. Sacroiliitis was found in 12 patients. The patients had high erythrocyte sedimentation rates, leukocytosis, and lack of antinuclear antibodies and rheumatoid factor. All 17 patients tested had HLA-B27 antigen. The patients with acute anterior uveitis showed aqueous flare, cells, fine keratic precipitates, and often exudates, posterior synechiae, vitritis, and macular edema. Acute anterior uveitis was mostly unilateral and resolved during corticosteroids on the average during the first six weeks; recurrences were seen in about half of the cases. Conjunctivitis was generally mild with no chemosis, follicles, or keratitis; and it resolved in one week without treatment. Our results indicate that in HLA-B27 positive patients infective agents can trigger acute anterior uveitis or conjunctivitis, which often occur together with rheumatic diseases.

We studied characteristics of ocular inflammation in Reiter's disease after Salmonella enteritis in eight patients. After an acute onset with diarrhea, fever in six patients, and headache in three patients, all patients developed arthritis; six patients had myalgia; six patients, urethritis; and one patient, carditis. Sacroiliitis was found in four patients. All patients had HLA-B28 antigen. Conjunctivitis occurred in seven patients. It was mostly mild with no chemosis, follicles, or keratitis, and resolved in ten days. In one case palpebral edema, chemosis in the conjunctiva, and purulent exudate were seen. One patient had transient episodes of keratitis and corneal erosion for two months and episodes of conjunctivitis for 11 months. Three patients developed unilateral acute anterior uveitis with aqueous flare, cells, fine keratic precipitates, and fibrinous exudation from three to four years after the onset of the illness. One of these patients had vitritis and macular and papillary edema.

Reiter's syndrome is commonly associated with conjunctivitis and rarely with uveitis. Bilateral disciform keratitis at presentation is a very rare manifestation in Reiter's syndrome. A 13-year-old boy developed bilateral disciform keratitis with oligoarthritis following an episode of conjunctivitis. In addition he had suspected bacterial keratitis with hypopyon in the left eye as a possible secondary infection of an epithelial defect that is a feature of Reiter's keratitis. Empirical treatment with intensive topical antibiotics as a therapeutic trial completely resolved the hypopyon and the disciform keratitis settled with topical steroid treatment. The patient achieved a best corrected vision of 20/20 in both the eyes 6 weeks after the treatment. Bilateral disciform keratitis can occur as a complication of Reiter's syndrome. Also the possibility of secondary infection of the epithelial defect needs to be borne in mind.
