General Discussion

Congenital fibrosis of the extraocular muscles (CFEOM) includes at least five rare genetic eye movement disorders present at birth that are characterized by incomitant strabismus. Specifically, there is an inability to move the eyes in certain directions (opthalmoplegia), droopy eyelids (ptosis) and eyes that are fixed in an abnormal position. The oculomotor nucleus and nerve (cranial nerve III) and the muscles it serves and, in some cases the trochlear nucleus and nerve (cranial nerve IV) and/or the abducens nucleus and nerve (cranial nerve VI) and the muscles they serve are affected.
