Prognosis
Diagnosis and Prognosis: The diagnosis may be suspected at birth by a pediatrician but because of the widespread congenital anomalies it may require collaboration with neurologists, ophthalmologists, orthopedists, and geneticists. [disorders.eyes.arizona.edu]
Prognosis Currently, there is no correlation between the genotype and phenotypes, so clinical severity of disease cannot be correlated with certain variants. [emedicine.medscape.com]
It is associated with a poor visual prognosis. [findzebra.com]
