13. The inferior oblique as muscle of choice for biopsies of extraocular muscles.
Suitable biopsies can easily be taken from the inferior oblique muscle without unwanted side effects from the belly of this muscle, allowing complete examination by light and electron microscopy. The inferior oblique is the muscle of choice for biopsy studies of extraocular muscle.

14. Graves' ophthalmopathy: I. Simple CT estimates of extraocular muscle volume.
Graves' ophthalmopathy is an autoimmune inflammatory process affecting primarily the extraocular muscles. The enlargement of these muscles is responsible for most of the important manifestations of the disease, including proptosis, lid retraction, diplopia, and optic neuropathy. Recently the optic neuropathy has been shown to correlate with extraocular muscl

15. Primary orbital amyloidosis localised to an extraocular muscle.
Primary, localised orbital amyloidosis has been reported previously in only 15 patients. A case with amyloidosis strictly localised to an extraocular muscle is presented.

16. Contractile properties of single skinned fibres from the extraocular muscles, the levator and superior rectus, of the rabbit.
1. The superior rectus and levator palpebrae superioris (levator), two of the extraocular muscles, were dissected from the rabbit and stored in a glycerol-based solution at -20 degrees C in order to prepare single, skinned fibres. 2. The Ca(2+)- and Sr(2+)-activated isometric contractile properties were determined for individual extraocular muscle fibres. Fi

17. The oculocardiac reflex as a surgical aid in identifying a slipped or 'lost' extraocular muscle.
The oculocardiac reflex during strabismus surgery has generally been regarded as a hazard capable of causing death. Six cases are presented which show a beneficial use of the oculocardiac reflex. Isolation of a previously slipped or 'lost' extraocular muscle can be difficult. In this series identification of the tissue as muscle was substantiated by observin

18. Extraocular muscle surgery for Graves' ophthalmopathy: does prior treatment influence surgical outcome?
We analysed the results of extraocular muscle surgery in 38 patients with stable Graves' ophthalmopathy. Fixed sutures were used in all patients. A useful field of binocular single vision was achieved in 27 patients (71%) after one operation and in seven patients (18%) after more than one, whereas double vision was persistent in four (11%). No recurrence of

19. An unusual extraocular muscle anomaly in a patient with Crouzon's disease.
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 s

20. Spiral nerve endings and dapple motor end plates in monkey extra-ocular muscles.
The suggestion that spiral nerve endings in extra-ocular muscles are sensory was tested. Spiral, serpentine and pincer-like endings were identified in extra-ocular muscles of rhesus and cynomolgus monkeys in light and electron microscopic preparations. Spiral and other complex nerve endings each terminated in the motor end plate zone as well separated cluste

22. Spiral nerve endings in human extraocular muscles terminate in motor end plates.
The long held view that spiral nerve endings in extraocular muscles are sensory, recently shown to be incorrect for monkeys, was tested in man. Muscle samples were taken from orbits of five patients after eye enucleation and prepared for light and electron microscopy. Most spiral endings terminated in the motor end plate band in several well separated cluste

23. Extraocular muscle is defined by a fundamentally distinct gene expression profile
Skeletal muscle fibers are defined by patterned covariation of key traits that determine contractile and metabolic characteristics. Although the functional properties of most skeletal muscles result from their proportional content of a few conserved muscle fiber types, some, typically craniofacial, muscles exhibit fiber types that appear to lie outside the c

24. Ocular myasthenia: evaluation of Tensilon tonography and electronystagmography as diagnostic tests
The value of electronystagmography (ENG) and of tonography in monitoring the beneficial effect of edrophonium chloride (Tensilon) on the extraocular muscles in myasthenia gravis has been assessed. Studies were performed on 17 patients with myasthenia gravis and on 18 control subjects, of whom nine had extraocular muscle weakness due to myopathic or neurogeni
