A case history of a 15-year-old schoolgirl with fluctuating bilateral uveitis, bilateral stromal keratitis with vascularisation, and bilateral deafness associated with tinnitus and balance disturbance is described. Three years from the onset of her clinical signs she died of a sudden cardiac arrest caused by endocarditis associated with valvular and arterial lesions. Chlamydia psittaci was isolated from her conjunctiva. In her blood type-specific antichlamydial antibody at a level of 1/64 against her own isolate was detected. The clinical findings in this patient were suggestive of a Cogan's syndrome. It is highly probable that the chlamydia isolated from the eyes was responsible for her various lesions.

Seventy free-ranging koalas (Phascolarctos cinereus) from Magnetic Island (Queensland, Australia) underwent an ocular examination, blood collection and serological examination for Chlamydia psittaci antibodies, and an examination of their teeth and genitalia. In 12 koalas long-standing unilateral keratitis was noted and in another 10 animals long-standing bilateral keratitis was observed. All animals were seronegative for Chlamydia psittaci and apart from some nasal discharge and a variety of assorted medical findings there was no sign of chlamydial infection. These ocular findings probably represent a new disease of unknown etiology.

Two cases of follicular conjunctivitis due to Chlamydia trachomatis followed by punctate epithelial keratitis are described. Both cases were initially treated with either oral tetracycline or doxycycline with resolution of the follicles. These two patients subsequently had recurrent, bilateral grayish lesions at various levels in the corneal epithelium that stained in a punctate fashion with fluorescein. There was anterior stromal edema associated with some of these lesions in one case. The lesions were confined mostly to the central cornea. These recurrent lesions were unassociated with a conjunctival reaction, were unresponsive to oral tetracycline, but were exquisitely responsive to low doses of topical steroids. Chlamydial conjunctivitis and the associated keratitis typically shows no response or actual exacerbation of symptoms with topical steroids, and the keratitis shows a predilection for the upper half of the cornea. These patients demonstrate that chlamydial keratoconjunctivitis might result in a clinical appearance consistent with Thygeson's superficial punctate keratitis.

173 nontrachomatous conjunctivitis studied at the I.O.T.A. in Bamako, Mali, have shown a majority of bacterial aetiology, especially gram-negative. 1 out of 10 conjunctivitis was due to virus, mostly to adenovirus. 4% of the cases were due to Chlamydia Trachomatis. The try of validation of the clinical characters in comparison with the etiology has shown that Chemosis was an indicator of a bacterial conjunctivitis (OR = 2.4) and that the lack of purulent discharge was in connexion with the presence of a keratitis (OR = 7.7). On the one hand the frequency of gram-negative bacteria, on the other hand the potential gravity of the conjunctivitis in tropical area, would justify the use of gentamycin at first in nontrachomatous conjunctivitis.

In order to study the relationship between cell-mediated immune responses to Chlamydia trachomatis and the pathogenesis of human chlamydial eye disease, we have measured the peripheral blood lymphocyte proliferative responses to whole chlamydial elementary bodies in 40 subjects with oculogenital chlamydial infection of varying severity, 13 subjects with genital chlamydial infections and 12 healthy seronegative controls. The mean stimulation index was significantly higher in those with oculogenital infections than in controls. There was a strong correlation between the response to C. trachomatis serotypes B and L1. We studied the relationship between proliferative responses and four clinical parameters: follicular conjunctivitis, papillary hypertrophy, corneal pannus and epithelial punctate keratitis, but were unable to show a significant association with any of these. Nor was there any association between proliferative response and serum antibody titre to C. trachomatis (pooled serotypes D-K), duration of disease or quantitative isolation of chlamydia from the conjunctiva. The depletion of CD8+ cells had no consistent effect on proliferative responses to serotype L1 in 13 subjects.

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.

In four patients with an adult chlamydial ophthalmia small, marginal corneal abscesses were detected. These corneal abscesses were associated with unilateral papillary and follicular conjunctivitis and punctate keratitis. In these patients no bacteria was isolated from the abscesses, but Chlamydia trachomatis was isolated from materials collected from the abscesses and from the conjunctival swabbings. In addition all patients had microbiologically proved concomitant chlamydial genital infections. The clinical signs resolved after topical treatment with rifampicin or tetracycline eye ointment for six weeks or systemic treatment with tetracycline for two weeks. Because of concomitant chlamydial genital infection it is advisable to treat patients with adult chlamydial ophthalmia with systemic tetracycline and to refer these patients and their consorts for investigation and treatment of their genital infection.

The presence of 12 viral (herpes 1 and 2, influenza A(H1N1), A(H3N2) and B, parainfluenza 1, 2, 3, adenovirus 5) and inframicrobial (Chlamydia, mycoplasma, Rickettsia burneti) antigens was investigated by direct or indirect immunofluorescence (IF) reactions in exfoliated conjunctival cells from 110 patients with nonbacterial keratitis and keratoconjunctivitis. A rapid etiological diagnosis could be obtained in 101 (92%) of the cases, parainfluenza and herpes antigens being the most frequently detected. In most of the cases the simultaneous presence of several antigens was made evident. Encouraging results were obtained by the application of a specific treatment based on the diagnosis provided by the IF reaction.

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 evaluated the susceptibility of alpine ibex (Capra ibex ibex) to mycoplasmal conjunctivitis induced by a strain of Mycoplasma conjunctivae isolated from domestic sheep by inoculation of three alpine ibexes with 1.2 x 10(6) colony forming units of M. conjunctivae in the conjunctival sac of both eyes. One more ibex was exposed to the infection by contact. Experimental animals were free of M. conjunctivae and ocular Chlamydia infection before inoculation. Conjunctivitis and serous to mucous lachrymation became apparent in all four ibexes. Clinical signs began within 2 days in inoculated animals and 22 days after the beginning of the experiment in the contact ibex. M. conjunctivae was demonstrated up to the 63th day post-inoculation by cultural and PCR-methods. After 63 days, histopathologic examination revealed nearly normal ocular tissues, and M. conjunctivae could be detected from two eyes only. No other infectious agents which might cause conjunctivitis or keratitis, including Chlamydia psittaci and Branhamella ovis, were involved. Our investigation indicates that sheep-strains of M. conjunctivae can induce conjunctivitis in alpine ibex, thus showing pathogenicity of this organism for Caprinae species other than domestic sheep and goats.
