Progressive retinal degeneration in a girl with Knobloch syndrome who presented with signs of ocular albinism

摘要

We report for the first time electroretinographic (ERG) evidence of progressive retinal abnormalities in a girl who presented in infancy with ocular features of albinism and gradually developed choroidal sclerosis and patchy retinal atrophy leading to a diagnosis of Knobloch syndrome (KS, OMIM 267750, COL18A1).
