Chronic progressive external ophthalmoplegia with atypical retinal pigment dystrophy (author's transl)

A brief review of the literature on chronic progressive external ophthalmoplegia is followed by a description of two unusual cases. The first, Kearns-Shy syndrome, was a pronounced case of "ophthalmoplegia-plus syndrome", though with normal retinal function. The second patient had retinal pigment dystrophy with severe disturbance of retinal function, as well as a complete lack of ocular motility.
