The paper reports on a clinical case of occlusion of retinal venous arm in both eyes, at a time interval of 6 months, the right eye being the former affected. The clinical observation showed the following: symmetrical topographic sites (superotemporal venous arm); existence of arteriovenous crossing in the occlusion site; ischemic capillaropathy with serious macular involvement. The clinical and lab examinations did not show pathogenic elements. The paper discusses largely on the role of arteriovenous crossing and of arteriosclerosis in the pathogeny of affection, the visual prognosis and on some therapeutic considerations.

[Treatment of chorioretinal degeneration and dystrophy].

Although the etiopathogenesis of chorioretinal degeneration and dystrophy is unknown the therapeutical means applied have been efficient. Disc-like degeneration can be treated by photocoagulation only in the stage of complication of subretinal neoformation of vessels. Recent pathogenic studies now offer therapeutical prospects in this severe ocular affection.

[Clinical chorioretinal aspects of systemic immune vasculitis. I. General aspects].

The eye, due to its rich vascularity, is frequently involved, directly or not, in the systemic immune vascular pathology. For a better understanding of the ocular clinical syndrome, the paper discusses the etiologic and pathogenic factors, and their influence on the characteristics of chorioretinal changes. The etiologic factors are classified according to the predominance of the lesions of the choroidal or retinal vessels. The pathogeny of the chorioretinal changes is correlated with the histopathologic lesion (fibrinoid necrosis) and its involvement in the "choriocapillaris complex-brush membrane-EPR". Clinical chorioretinal syndrome, irrespective of its etiology, induces several retinal and choroidal changes having varied as a function of the evolution stage.

[Clinical chorioretinal aspects in systemic immune vasculitis. II].

Systemic immune vascular pathology raises very often diagnosis and differential diagnosis difficulties generated by the multitude and polymorphism of its clinical symptomatology. Chorioretinal modifications, sometimes particular, may complete the general clinical picture of the systemic immune vasculitis, favouring a correct clinical diagnosis. At the same time, a better knowledge of the clinical picture of some general systemic affections may lead to a correct diagnostic interpretation of these chorioretinal modifications. The paper presents the author's own classification of the main systemic immune vasculitis and also several rare affections (with immunologic implications) with emphasis on the vascular chorioretinal syndrome and on the clinical general one.
