Acquired oculomotor muscle fibrosis in infant: case report [PDF]
Arquivos Brasileiros de Oftalmologia, 2011 The authors report the case of a 5 year-old boy who up to 2 years old presented normal eyes, when his right eye started to deviate upward and laterally, until be hidden under the superior lid. At the surgery, a strong passive limitation to infraduction of this eye was felt.

The intimate nature of oculomotor muscles contracture [PDF]
Arquivos Brasileiros de Oftalmologia, 2010 The author makes comments about the shortening and loss of elasticity of the oculomotor muscle that remains slack for some time (contracture), by means of a reasoning based on the Hooke s law and on the papers carried out to demonstrate that a muscle that remains relaxed for some time suffers a shortening due to loss of sarcomeres on the longitudinal ...

Abnormalities of the Oculomotor Nerve in Congenital Fibrosis of the Extraocular Muscles and Congenital Oculomotor Palsy [PDF]
Investigative Opthalmology & Visual Science, 2007 High-resolution magnetic resonance imaging (MRI) can now directly demonstrate innervation to extraocular muscles and quantify optic nerve size. A quantitative MRI technique was developed to study the oculomotor nerve (CN3) and applied to congenital fibrosis of extraocular muscles (CFEOM) and congenital oculomotor palsy.The subarachnoid portions of the ...

Does extraocular muscle proprioception influence oculomotor control? [PDF]
British Journal of Ophthalmology, 2000 Disorders of ocular motility are encountered on a regular basis within ophthalmic practice. They include a wide variety of conditions from non-paralytic strabismus commonly seen in paediatric clinics to acquired restrictive and paralytic conditions, which may be indicative of more serious underlying pathology.

Oculomotor adaptation to prisms is not simply a muscle potentiation effect [PDF]
Perception & Psychophysics, 1975 An experiment is reported in which subjects pointed to a visual target before and after exposure to prisms. The exposure condition required the subject to look at his feet through leftward deviating prisms while holding his eyes to the right. Aftereffects on pointing were significantly to the right.

Acquired ptosis associated with oculomotor and contralateral facial nerve synkinesis: the first reported case [PDF]
, 2017 Evidence of oculomotor nerve (ON) synkinesis is a common occurrence following both acquired and congenital III nerve palsy. It is generally accepted that aberrant regeneration is the likely aetiology of synkinesis in acquired III nerve palsy, following ...

Axons Giving Rise to the Palisade Endings of Feline Extraocular Muscles Display Motor Features [PDF]
, 2013 Palisade endings are nerve specializations found in the extraocular muscles (EOMs) of mammals, including primates. They have long been postulated to be proprioceptors. It was recently demonstrated that palisade endings are cholinergic and that in monkeys

Analog VLSI-Based Modeling of the Primate Oculomotor System [PDF]
, 1998 One way to understand a neurobiological system is by building a simulacrum that replicates its behavior in real time using similar constraints. Analog very large-scale integrated (VLSI) electronic circuit technology provides such an enabling technology ...

Functional diversity of motoneurons in the oculomotor system [PDF]
, 2019 Extraocular muscles contain two types of muscle fibers according to their innervation pattern: singly innervated muscle fibers (SIFs), similar to most skeletal muscle fibers, and multiply innervated muscle fibers (MIFs).

Recurrent cerebellar architecture solves the motor-error problem [PDF]
, 2004 Current views of cerebellar function have been heavily influenced by the models of Marr and Albus, who suggested that the climbing fibre input to the cerebellum acts as a teaching signal for motor learning.
