Term ID: 30637
Name: Congenital stationary cone dysfunction
Synonym: Cone dysfunction; Cone dysfunction syndrome
Definition: Retinal phenotype characterised by cone photoreceptor dysfunction and preserved rod system. The abnormality is typically stationary or very slowly progressive and findings may include reduced central vision, colour vision abnormalities, nystagmus and photophobia.
