Primary and secondary overacting inferior oblique muscles: an ultrastructural study.
Biopsy material from primary and secondary overacting inferior oblique muscles were examined by light and electron microscopy. Most muscle fibres were in different stages of atrophy. A high variation of alterations was encountered in all muscles. The most striking abnormalities were huge accumulations of mitochondria and muscle vacuolisation related mainly to the enlargement of the tubules of s...

BACKGROUND Inferior oblique muscle overaction of variable amounts is usually present with congenital superior oblique palsy. Inferior oblique muscle anteriorization has been described as a suitable surgical procedure in this entity. The aim of this study was to investigate the effect of inferior oblique muscle anteriorization in patients with congenital superior oblique palsy on vertical, torsi...
متن کاملOutcomes of Unilateral Inferior Oblique Myectomy Surgery in Inferior Oblique Overaction Due to Superior Oblique Palsy
OBJECTIVES To present the outcomes of unilateral inferior oblique myectomy performed in patients with inferior oblique overaction due to superior oblique palsy. MATERIALS AND METHODS Twenty-seven eyes of 27 patients that underwent inferior oblique myectomy surgery for superior oblique palsy between 2002 and 2008 were included.

متن کاملAnterior and nasal transposition of the inferior oblique muscles in patients with missing superior oblique tendons.
INTRODUCTION Patients with missing superior oblique (SO) tendons present with overelevation/underdepression in adduction. Unilateral cases often exhibit abnormal head postures, whereas in bilateral cases, there may be a marked V-pattern with upgaze exotropia. These patients may have craniosynostosis. METHODS Nine children with unilateral (n = 2) or bilateral (n = 7) absent SO tendons underwen...
متن کاملMagnetic resonance imaging of the functional anatomy of the inferior oblique muscle in superior oblique palsy.
PURPOSE To study size and contractility of the normal inferior oblique (IO) muscle using high-resolution magnetic resonance imaging (MRI) and to evaluate abnormalities of the superior oblique (SO) and IO muscles in chronic SO palsy. DESIGN Prospective, case control study. PARTICIPANTS Thirteen patients with SO palsy and 17 orthotropic subjects. METHODS High-resolution, surface coil MRI wa...
