Differential Change in Retina Structure and Function in Children and Adolescents with Drusens of the Optic Nerve Disk

Oftalʹmologiâ, 2018
The first histological and clinical description of the optic nerve drusens was given in the 19th century. Then authors considered drusens as congenital pathologies, and a study of 1999 showed that drusen is not the primary pathology, but the dysplasia of
