Abstract
Purpose: To investigate nervus abducens and extraocular mucles in patients with Type 1 Duane's retraction syndrome using high-definition magnetic resonance imaging. Methods: The study included 10 patients with Type I Duane's retraction syndrome who underwent magnetic resonance imaging (MRI) of the brain and orbits. Results: Overall, 10 cases were included in the study. There were seven women and three men. The mean age was 5.2 years (1-15 years). MRI of the abducens nerve was performed in all cases. Of the cases, the left eye was involved in eight cases, whereas the right eye was involved in two cases. There was no bilateral eye involvement. Among the 10 patients clinically diagnosed as Type 1 Duane's retraction syndrome, the abducens nerve could not be visualized in eight cases, whereas the nerve was hypoplastic in one case and bilateral abducens nerves were present in one case by MRI. The extraocular muscles were normal in all cases on T2 weighted coronal MRI of the orbits. Conclusion: Absence of abducens nerve and normal extraocular muscles was detected in patients with Type 1 Duane's retraction syndrome at the affected side.
