In 1910, Mitsuda published a monograph on "Eye Leprosy", in which he reported an autopsy case with many miliary, disseminated, gray-yellowish leproms on the posterior surface of the ciliary body, inspecting inside macroscopically after cutting the bulbus frontal at the equator.
The author, Shionuma, studing under Mitsuda, examined 78 leprosy eyes in the same way, and found such leproms in 48.48% of nodular(C) cases by autopsy.
The number of the leproms is most in Orbiculus ciliaris, (pars non plicata), especially in the lower part, as seen in the table 2 and 3.
The lower outer part is predominant for these leproms.
These small leproms consist of proliferated and desquamated pigment epithels of corpus ciliare and ora serratis of retina, which are used to phagocyte leprosy hacilli, often even globis, and fall down on the lower part of the posterior surface.
