Cystinosis is a rare autosomal recessive lysosomal storage disorder 
characterized by abnormal accumulation of intracellular cystine in various 
tissues including the brain, kidneys, bones, and eyes. Infantile nephropathic 
cystinosis is the most severe phenotype of cystinosis that has been associated 
with a wide spectrum of ocular features. In this report, the author describes a 
posterior segment spectral-domain optical coherence tomography (SD-OCT) finding 
that has not been previously reported in a case of nephropathic cystinosis.
