The authors have followed the evolution of disseminated choroidal tuberculosis during a period of 16 months. At the beginning of the disease, fluorescein angiography showed an early ‘screen effect’ and later a ‘focus effect’. During the later stage of the disease, the pigmented epithelium was seen to be involved as well, as demonstrated by (1) the presence of advanced pigmented chorioretinitis at the sites where the tubercles were observed at the beginning of the disease and (2) the presence of fluorescent areas early during fluorescein angiography.
