PURPOSE We report a case of inferior rectus muscle aplasia in a 65-year-old woman. METHODS Images were obtained using ocular motility photography and magnetic resonance imaging (MRI), and operative findings were analyzed. RESULTS A 65-year-old woman presented with marked right hypertropia. The right eye also had microcornea, iris coloboma, and completely restricted downward movement. MRI sh...

PURPOSE To investigate the degree of reunion in rabbit eyes of the superior oblique tendon after several surgical weakening procedures. METHODS A total of 32 rabbits (64 eyes) were used in this study. The rabbits were randomly assigned to four groups, eight rabbits (16 eyes) in the tenotomy group, eight rabbits (16 eyes) in the tenectomy group, eight rabbits (16 eyes) in the disinsertion grou...

PURPOSE To characterize the relationship between inflammation and swelling of extraocular muscles in thyroid-associated ophthalmopathy before and after methylprednisolone pulse therapy. METHODS The signal intensities and volumes of the superior rectus (SR), inferior rectus (IR), lateral rectus (LR), medial rectus (MR), and superior oblique (SO) muscles were measured with magnetic resonance im...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014207749 DESCRIPTION A 44-year-old man with hyperlipidaemia and chronic hepatitis C infection presented with a 48 h history of diplopia and occipital headaches. On neurological examination, he was alert and afebrile. There was right oculomotor palsy consisting of right medial rect...

The pattern of axonal terminations of individual premotoneuronal medium lead burst neurons (MLBs) has been elucidated with the help of the intraaxonal recording and horseradish peroxidase injection technique in alert behaving monkeys. These findings indicate that individual MLBs do not influence individual muscles; instead they influence groups of muscles. Horizontal medium lead burst neurons (...

PURPOSE To search for a new definition of muscle hypoplasia in congenital or idiopathic superior oblique muscle palsy. DESIGN Retrospective case-control study. METHODS Cross-sectional areas of the superior oblique and 4 rectus muscles near the eye globe-optic nerve junction were measured by an image analysis software on magnetic resonance images of 50 patients with congenital or idiopathic ...

PURPOSE To examine the number and distribution of muscle spindles in all extraocular muscles (EOMs) in humans. METHODS Thirty-six EOMs were obtained after death from three persons 67, 72, and 83 years of age. Serial sections were made throughout the length of these muscles. Consecutive sections were stained with different methods. To discriminate true spindles from false spindles, light micro...

Two cases of osseous choristoma are described. One of the tumours was found in the conjunctiva of the right lower lid, an apparently unique location. The other more typical epibulbar tumour was found in the superior temporal quadrant of the episclera between the lateral and superior rectus muscles. In both instances the tumour was suspected of being a dermoid.

PURPOSE The authors established a surgical treatment for excyclovertical strabismus in which either the inferior rectus muscle or the superior rectus muscle was transposed diagonally. The effects and the safety of the procedure, called skew transposition, were studied. METHODS Eighteen operations using local anesthesia with eye drops were performed on 17 cases, including 10 with superior obli...
