[Malformation syndromes: the diagnostic approach and follow-up in ocular pathology].

Ocular defects are often found in association with many systemic disorders. Some are already present at birth, but in other cases they develop in early infancy or later in life. They are found associated with connective tissue disorders, neurological conditions, chromosomal abnormalities and dermatological disorders. Some of these syndromes have a genetic basis but often it is uncertain whether they are inherited and their cause is unknown.
