Rapid eye movements (REMs), traditionally measured using the electrooculogram (EOG), help to characterize active sleep in adults. In early infancy, however, they are not clearly expressed. Here we measured extraocular muscle activity in infant rats at 3 days of age (P3), P8 and P14-15 in order to assess the ontogeny of REMs and their relationship with other forms of sleep-related phasic activit...
PURPOSE Strabismus affects as many as 60% to 70% of patients with Crouzon syndrome. V-pattern strabismus is common and is thought to be secondary to severe oblique muscle dysfunction. The complex motility disorders produced by abnormal extraocular muscles in this syndrome can be difficult to manage. Few studies have reported findings regarding the extraocular muscles or how to plan and adapt th...
PURPOSE Three congenital fibrosis of the extraocular muscles phenotypes (CFEOM1-3) have been identified. Each represents a specific form of paralytic strabismus characterized by congenital restrictive ophthalmoplegia, often with accompanying ptosis. It has been demonstrated that CFEOM1 results from mutations in KIF21A and CFEOM2 from mutations in PHOX2A. This study was conducted to determine th...
Oculomotor disturbances commonly occur as manifestations of Graves’ Oohthalmomthv. We investieated the outcome of this disorderfollowing e&ernal-beam orbital radiotherapy. We conducted a prospective study on 15 patients to assess the extent of ophthalmopathy by clinical evaluation, and measurement of the amplitude of gaze and the thickness of the extraocular muscles on computed axial tomography...
A 29-year-old female suffering from Crouzon's disease was admitted to hospital with retinal detachment in the right eye. At operation agenesis of 4 extraocular muscles (superior and inferior recti and obliquus) was found, together with abnormal insertion of the 2 horizontal muscles. The same extraocular muscular abnormalities were found in the left eye. We suggest here a new surgical treatment ...

Extraocular muscle involvement in orbital disease is most frequently seen as a feature of thyroid orbitopathy (Graves' disease). However, a wide range of other conditions may alter the size, shape, and function of these muscles, with characteristic clinical manifestations or abnormalities visible on orbital imaging. The differential diagnosis of muscle disease can be narrowed by careful analysi...
