Dissociated strabismus complex (DSC) includes dissociated horizontal, vertical, torsional deviation, latent nystagmus and sub-normal binocularity [1]. It is usually bilateral but asymmetric; may manifest spontaneously or with cover testing. As clinical manifestation, DSC is a comitant drift of both eyes: the fixating eye manifests depression, adduction and intorsion and the nonfixating eye mani...

The diagnosis of Graves' orbitopathy is usually straightforward. However, orbital diseases that mimick some clinical signs of Graves' orbitopathy may cause diagnostic confusion, particularly when associated to some form of thyroid dysfunction. This report describes the rare occurrence of localized inferior rectus muscle amyloidosis in a patient with autoimmune hypothyroidism, who was misdiagnos...

BACKGROUND Rectus femoris tendon transfer is performed in patients with cerebral palsy to improve knee flexion during walking. This procedure involves detachment of the muscle from its insertion into the quadriceps tendon and reattachment to one of the knee flexor muscles. The purpose of the present study was to evaluate the muscle-tendon geometry and to assess the formation of scar tissue betw...

The paradigm that an "underacting" extraocular muscle is always atrophic or hypoplastic and that an overacting extraocular muscle should always be enlarged leads to inconsistencies with clinical observations. These include findings of "overacting" inferior oblique muscles, superior rectus muscle overaction or contracture syndrome, and normal extraocular muscle diameters in patients with apparen...

background: use of botulinum toxin is becoming a popular way in treatment of some forms of strabismus.to evaluate the morphological changes in the orbital surface layer muscles of the rabbit eye following a single injection of botulinum toxin.   methods: 10 white dutch rabbits weighing 2–3 kg received either 10 units (group 1; n=5) or 20 units (group 2; n=5) of botulinum toxin into the superior...
