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 ...

Seventy cases of space-occupying lesions in the eyeball and 140 extraocular masses in the orbit were explored by both sonography and compute tomography (CT). The merits of each method were demonstrated relative to defining the location, extension, and nature of the lesion. In adults with ocular masses, sonography is usually sufficient. For retinoblastoma, CT is usually necessary to rule out an ...

The objective of this study was to investigate the characteristics and distributions of neuronal origin of cerebellar afferents from motor cranial nerve nuclei innervating extraocular muscles by the method of retrograde transport of two fluorescence tracers in rats. Under deep anesthesia and aseptic conditions, 5 microl of 3% solution of Fluoro-Gold (FG) in phosphate buffer solution (PBS) was i...

During swimming in the amphibian ITALIC! Xenopus laevis, efference copies of rhythmic locomotor commands produced by the spinal central pattern generator (CPG) can drive extraocular motor output appropriate for producing image-stabilizing eye movements to offset the disruptive effects of self-motion. During metamorphosis, ITALIC! X. laevisremodels its locomotor strategy from larval tail-based u...

PURPOSE The purpose of this study was to identify the site(s) of MCMV latency and reactivation in the eye. METHODS Three months after supraciliary inoculation of 5 x 10(2) PFU of MCMV, BALB/c mice underwent immunosuppression with methylprednisolone and antibodies specific for CD4 T cells, CD8 T cells, and NK cells or with methylprednisolone alone. Control mice were infected but did not receiv...

PURPOSE Insulin-like growth factor 1 (IGF1) and cardiotrophin 1 (CT1) are known to increase the strength of extraocular muscles in adult and embryonic animals, but no information is available for the early postnatal period, when strabismus treatment in humans is most urgent. Here the authors sought to determine whether these trophic factors strengthen juvenile maturing extraocular muscles and g...

We have measured extraocular muscle function in 41 patients who received neuromuscular block with mivacurium 0.2 mg kg-1 during anaesthesia with propofol, ketorolac, fentanyl and isoflurane in nitrous oxide and oxygen, which was antagonized at the end of surgery with neostigmine 0.05 mg kg-1 and glycopyrronium 0.01 mg kg-1 in 21 of these patients. Extraocular muscle function was measured before...

BACKGROUND Anecdotal evidence has previously suggested that retrobulbar local anaesthetic (LA) injection is accompanied by the rapid onset of ptosis. Here the validity of this potentially valuable sign is tested. METHODS 25 patients received a retrobulbar injection and the times for development of ptosis and akinesia in other extraocular muscle groups were recorded and compared. The effects o...
