Blue dot cataract/ cataracta punctata caerulea was first described by Vogt- it is not a true congenital cataract but is a form of developmental cataract
Autosomal dominant inheritance- genes located on 17q and 22q
Characteristic discrete punctate opacities (round bluish dots) situated in the peripheral part of adolescent nucleus and deeper layers of cortex forming a concentric layer with central ones radially oriented
Stationary, non-progressive opacities which are not visually significant and hence do not necessitate surgical intervention.
