RESUMEN
We report two cases of thrombotic thrombocytopenic purpura (TTP). The first case illustrates the clinical findings and fluorescein angiographic features of this disease, notably the serous macular detachments and focal areas of choriocapillaris occlusion. The second case demonstrates a more severe case of TTP, with neurologic complications that led to death; histopathological examination of the eyes showed serous retinal detachments and choriocapillaris occlusion, with electron microscopic evidence of intravascular fibrin-platelet thrombi.

A 77-year-old white woman presented with a lightly pigmented iris lesion assumed clinically to be an iris melanoma. Light microscopy of the excised tumour showed it to be a spindle-cell tumour. Electron microscopy confirmed the diagnosis of leiomyoma of the iris.
