1. Avaliação clínica da atividade eletromiográfica dos músculos óculo motores em pacientes portadores de próteses oculares individualizadas / Clinical evaluation of the electromyographic activity of the eye muscles in patients with individualized ocular prostheses
As próteses oculares têm a função de restabelecer a estética simultaneamente à manutenção da forma anatômica da cavidade orbital, preservando o tônus muscular palpebral e inibindo o colapso palpebral. Como poucos trabalhos científicos foram realizados para avaliar a recuperação de tônus muscular em indivíduos com necessidade de próteses ocula

2. Avaliação precoce do comportamento oculomotor em bebês com displasia broncopulmonar / Early assessment of oculomotor behavior in babies with bronchopulmonary dysplasia
O presente estudo avaliou o sistema oculomotor medido por movimentos oculares em bebês com diagnóstico de Displasia Broncopulmonar (DBP). Bebês com idade gestacional 37 semanas, dependentes de oxigênio em concentrações acima de 21% por mais de 28 dias foram incluídos no grupo DBP, bebês nascidos a Termo (idade gestacional >37 semanas), não internado

3. Anatomical study of the opossum (Didelphis albiventris) extraocular muscles.
The anatomy of the extraocular muscles was studied in 10 adult opossums (Didelphis albiventris) of both sexes. Eight extraocular muscles were identified: 4 rectus muscles, 2 oblique muscles, the levator palpebrae superioris and the retractor ocular bulbi. The rectus muscles originate very close one to another between the orbital surfaces of the presphenoid a

5. Unexpected role of the oblique muscles in the human vertical fusional reflex.
1. If a weak vertically oriented prism is inserted before one eye, binocular single vision is restored by vertically divergent eye movements (one eye turning upward, the other downward); and it is usually assumed that the vertical rectus muscles mediate that fusional reflex. 2. When vertically divergent eye movements occur, both eyes also systematically rota

6. Results in 50 cases of strabismus after graduated surgery designed by A scan ultrasonography.
Of 50 cases of strabismus having surgical operations designed on the basis of A scan ultrasonography 45 (90%) had less than 10 dioptres eso- or exodeviation two months postoperatively; 22 eso-, 25 exo-, and 3 vertical deviations were included in the series. A scan ultrasonography is done preoperatively to find the diameter and thus the circumference of the g

7. Localisation of motoneurons supplying the extra-ocular muscles of the rat using horseradish peroxidase and fluorescent double labelling.
This paper describes a qualitative and quantitative investigation into the location of the motoneurons innervating the extra-ocular muscles of the rat. Injections of horseradish peroxidase, bisbenzimide, propidium iodide and DAPI-primuline were made either in one or simultaneously in two muscles. Unlike those of the cat, rabbit and monkey, the motoneurons wh

8. Passive ocular proptosis.
Two patients with oculomotor neuropathy demonstrated passive ocular proptosis. In both instances, there was no evidence of a pathological process exerting a vector of force through the orbital opening. The proptosis is caused by a combination of the loss of the normal backward force exerted by the ocular recti muscles and the presence of a small anteriorly d

9. Fibre analysis of the nerve to the inferior oblique muscle in monkeys.
The nerves to the inferior oblique muscles from both sides of four rhesus and seven cynomolgus monkeys were examined by light and electron microscopy. Myelinated fibres averaged slightly over 3000 in rhesus and 2000 in cynomolgus monkeys, with a bimodal distribution of diameters in both, the lower peak being 2.5-3.0 micron and the upper 7-11 micron, the larg

10. Pseudorabies Virus-Induced Leukocyte Trafficking into the Rat Central Nervous System
When the swine alphaherpesvirus pseudorabies virus (PRV) infects the rat retina, it replicates in retinal ganglion cells and invades the central nervous system (CNS) via anterograde transynaptic spread through axons in the optic nerve. Virus can also spread to the CNS via retrograde transport through the oculomotor nucleus that innervates extraocular muscles

11. Innervation of the iris by individual parasympathetic axons in the adult mouse.
Ciliary neurones were identified electrophysiologically in isolated ganglia and the projection of individual axons to the intrinsic muscles of the eye determined by labelling identified cells with horseradish peroxidase (HRP). The ciliary ganglion of the adult mouse contains 80-100 parasympathetic neurones clustered at the point where the oculomotor nerve br
