[Apropos of a case of bilateral perforating corneal ulcer in a patient with Portugese amyloidosis].

Purpose: Corneal ulcer is a very rare clinical manifestation in hereditary familial amyloidosis of the Portuguese type, from which only one case has been reported previously. The case of a 35-year-old man illustrates the diagnostic findings and the difficulties encountered in understanding the physiopathology of such a complication.

Patient: The patient was referred by his general practician because of bilateral visual impairment since few days.

[Uveitis associated with rifabutin treatment. Apropos of 3 patients].

Disseminated Mycobacterium-avium complex (MAC) infection develops in most patients with AIDS. We report three cases of anterior uveitis with vitritis in AIDS patients treated by the combination of rifabutin, clarithromycin and ethambutol for MAC bacteremia. Uveitis secondary to the introduction of rifabutin treatment is suggested.

[Foldable implants in cataract surgery at the Geneva Ophthalmological Clinic].

Purpose: Since 1993, foldable intraocular lenses (Adatomed 90 D, Allergan SI26NB et SI30NB, Chiron C10, Medilas 127) have been implanted through a corneal or scleral tunel after phakoemulsification of the cataract. This retrospective study is made for evaluating the advantages and the disadvantages of these new silicon implants.

Patients And Method: The first 250 implantations of a silicon foldable lens compared to 50 rigid PMMA lenses.

[Diagnostic aspects and frequency of retrocorneal precipitates in diagnosis of cytomegalovirus retinitis in the HIV+ patient].

Cytomegalovirus retinitis (CMV) is the most common ocular opportunistic infection seen in patients with acquired immune deficiency syndrome. The anterior segment is usually quiet or with minimal aqueous humour flare and cell reaction. Nevertheless, in this prospective study of 30 eyes with CMV retinitis, 22 (73%) had white, small and filamentous keratic precipitates (KPS) which seem to corroborate this inflammation.

[Uveitis complicating posterior segment neovascularization. Six cases].

Subretinal or preretinal neovascularisation may be occasionally observed during the evolution of certain forms of uveitis. Subretinal neovascularisation commonly begins at the level of the chorioretinal uveitic scars. Consequently, the alteration of the retinal pigment epithelium-Bruch's membrane-choriocapillaris complex is the apparent cause.
