Description : Norrie disease is an X-linked recessive disorder characterized by very early childhood
blindness due to degenerative and proliferative changes of the neuroretina. Approximately
50% of patients show some form of progressive mental disorder, often with psychotic
features, and about one-third of patients develop sensorineural deafness in the second
decade. In addition, some patients have more complex phenotypes, including growth
failure and seizures (Berger et al., 1992). Warburg (1966) noted confusion of the
terms 'pseudoglioma' and microphthalmia with Norrie disease in the literature. 'Pseudoglioma'
is a nonspecific term for any condition resembling retinoblastoma and can have diverse
causes, including inflammation, hemorrhage, trauma, neoplasia, or congenital malformation,
and often shows unilateral involvement. Thus, 'pseudoglioma' is not an acceptable
clinical or pathologic diagnosis (Duke-Elder, 1958).;
