Abstract：Objective To investigate the value of 3D-Fiesta sequences for showing ophthalmic motion nerves and extraocular muscles abnormalities in the complex strabismus of children.Methods Eighteen patients with complex strabismus underwent MRI examination on 3.0 T MR unit.Ophthalmic nerves to extraocular muscles were imaged and analyzed with 3D-Fiesta scanning sequences in all patients.Results Patients with duane syndrome (11 cases, 15 eyes) all exhibited absence or hypoplasia of ab-ducens nerve ( CN6) and there were no hypoplasia of EOMs.Patients with congenital fibrosis of EOMs (3 cases, 5 eyes) exhibi-ted severe hypoplasia of CN3 and CN6, and EOMs appeared hypoplasia to a different degree, particularly severe for the superior rectus.Multiple nerves displayed aplasia in patients with Mobius syndrome (4 case, 7 eyes) and there were hypoplasia of the lat-eral rectus in two cases.Conclusion Using 3D-fiesta scanning sequences could directly demonstrate absence or hypoplasia of ophthalmic nerves and abnormalities of corresponding extraocular muscles, which indicates its important value of clinical applica-tion in congenital complex strabismus.
