But	To describe the genetic conditions leading to limitation of the movements of the external ocular muscles, also known as external ophthalmoplegia.
Méthodes	A systematic review of the literature, and of cases from the ophthalmic genetics clinics at the Ghent University Hospital.
Résultats	Genetic conditions leading to external ophthalmoplegia include Möbius syndrome, mitochondrial conditions such as progressive external ophthalmoplegia, Leigh disease and Kearns-Sayre syndrome, autosomal dominant optic atrophy with deafness, ptosis and progressive external ophthalmoplegia, Steinert myotonic dystrophy, spinocerebellar ataxia type 7, congenital fibrosis of the extraocular muscles (AD CFEOM1 & CFEOM3 and & AR CFEOM2).
Conclusion	The genetic conditions leading to external ophthalmoplegia are diverse and reflect very different mechanisms of disease.
