Retinal vascular occlusions in open heart surgery.
This study describes microthrombotic emboli (with their ultrastructure) and emboli of fat and of dimethylpolysiloxane with silica in the retinal microcirculation of two patients who died-each after his second open heart operation. The presence of silica was confirmed by electron probe x-ray micro-analysis.
