Unilateral congenital fibrosis of the extraocular muscles with lid retraction: surgical treatment with a silicon plate on the orbital floor.

Fibrosis of the extraocular muscles can be an acquired or congenital disorder (CFEOM). The congenital disorder(1) is a complex strabismus with congenital restrictive ophthalmoplegia with or without ptosis. The surgery is challenging because the eye muscles are replaced by fibrous tissue or fibrous bands and in most cases the results are not satisfactory.

Left-sided Duane's syndrome and retinal coloboma associated with contralateral microphthalmia.

Case report of a 15-year-old girl presenting with a left-sided Duane's retraction syndrome (DURS) in combination with ipsilateral retinal coloboma and contralateral microphthalmia. Abduction limitation as well as narrowing of the palpebral fissure and globe retraction during attempted adduction (type I DURS) was demonstrated in the left eye. Additionally, a retinal coloboma was observed in the nasal inferior quadrant of the left eye.
