  • Senior-Løken syndrome is a rare autosomal recessive disease with a prevalence of 1:1,000,000.

  • Retinopathy may progress as Leber congenital amaurosis (LCA), retinitis pigmentosa (RP), or sector RP (Figs. 34.1 and 34.2).

  • Onset of photophobia, nystagmus, and hyperopia can occur in the first few years of life or later in childhood.

  • Patients experience nephronophthisis, characterized by cystic kidney disease (medullary cystic kidney disease), reduced concentrating ability, and chronic tubulointerstitial nephritis, which progresses to end-stage renal disease.

  • Hypertension is common.
