Medical Eponyms
Senior-Løken syndrome (1961)

Autosomal recessive disease with renal failure in childhood or adolescence (nephronophthisis) and Leber congenital amaurosis. A congenital disorder occurring in a juvenile and an adult type combining nephrophthisis and tapetoretinal degeneration. In the juvenile type with onset in early childhood, there is blindness and death from renal failure before the age of 10. The adult type is marked by a later onset and a milder course. [aka * renal-retinal syndrome; juvenile nephronophthisis with Leber amaurosis; renal dysplasia and retinal aplasia]

In March 1961 Loken et al published cases of a brother and sister with the main features of nephronophthisis and Leber congenital amaurosis. In November 1961 Senior et al also reported families with an oculorenal syndrome. 

Two siblings, a boy and a girl, with congenital blindness died at 8 and 9 years of age from renal failure. Autopsy was performed in one case. The kidneys showed evidence of dysplasia and of pyelonephritis. Earlier suggestions that renal dysplasia might be the primary cause in cases of chronic pyelonephritis in children are supported. Examination of the eyes indicated a congential defect, retinal aplasia.
