[Cilioretinal infarction and retinal vein occlusion].
Twenty cases of central vein occlusion associated with cilio-retinal infarction were studied. The following observations were made: the venous occlusion is mostly secondary to the central venous occlusion of the trunk itself (only one case of main branch occlusion). It is always an occlusion either on papillo-phlebitis or oedematous capillaropathy. In most cases, the evolution is benign, but in very few cases it is forwards is ischemic capillaropathy. Cilio-retinal infarction is secondary to the occlusion of one or several cilioretinal arteries which are not always involved. Injection of the cilioretinal artery is usually delayed in fluorangiography, sometimes there is a typical ebb and flow. Preretinal new vascularization may appear in case of persistent ischemia of a large cilioretinal territory. Functional prognosis depends first of all upon the location of the infarcted territory relative to the foveola. Pathogenesis of this association remains unclear, cilioretinal arterial and venous involvements are concomitant and interdependent, the cilioretinal occlusion seems to be connected with the decrease of the capillary perfusion pressure which is secondary to retinal venous occlusion.
