26 males and 13 female carriers of different ages with choroideremia of varying severity were investigated using sodium fluorescein (FAG) and/or indocyanine green (ICG) fluorescence angiography. Females with minor changes present in pigment epithelium amy stay unchanged throughout life or gradually develop into a more advanced stage resembling the fundus picture of severely affected males. In moderately affected females there is a patchy degeneration of pigment epithelium in the macula. Peripapillary degeneration is seen also in indocyanine green fluorescence angiograms. In males, atrophic areas and the remaining choriocapillaris are clearly demonstrated in FAG and less well visible in ICG angiograms. ICG angiograms show choroidal vessels more clearly in cases where the pigment epithelium and the choriocapillaris are still present. In advanced cases in males and females, the choroidal blood circulation is slow.

Two patients with subacute sclerosing panencephalitis (SSPE) are described because of the course of the disease, which is still thought to be unusual but might prove to be rather common. In both cases there was apparent recovery after about two years of illness. One of the patients had a relapse after eight years of remission and seems to have recovered also from this second period of illness, though with a more severe mental defect than after the first one. Thus, SSPE should be kept in mind as a possible aetiological factor in patients with a persisting slight to severe dementia after a brain disorder. Apparent recovery from SSPE does not exclude the possibility of relapse even many years later.
