| ocular vesicle | In the embryo, one of the paired evaginations from the ventrolateral walls of the forebrain from which the sensory and pigment layers of the retina develop. Synonym: vesicula ophthalmica, ocular vesicle, optic vesicle. (05 Mar 2000) |

| onchocerciasis, ocular | Filarial infection of the eyes transmitted from person to person by bites of onchocerca volvulus-infected black flies. The microfilariae of onchocerca are thus deposited beneath the skin. They migrate through various tissues including the eye. Those persons infected have impaired vision and up to 20% are blind. The incidence of eye lesions has been reported to be as high as 30% in central america and parts of africa. (12 Dec 1998) |
| toxoplasmosis, ocular | Infection caused by the protozoan parasite toxoplasma in which there is extensive connective tissue proliferation, the retina surrounding the lesions remains normal, and the ocular media remain clear. Chorioretinitis may be associated with all forms of toxoplasmosis, but is usually a late sequel of congenital toxoplasmosis. The severe ocular lesions in infants may lead to blindness. (12 Dec 1998) |
| tuberculosis, ocular | Tuberculous infection of the eye, primarily the iris, ciliary body, and choroid. (12 Dec 1998) |
| extra-ocular muscle disease | <radiology> Graves disease, pseudotumour, lymphoma, metastasis, infection, carotid-cavernous fistula, granulomatous disease (12 Dec 1998) |
| unit of ocular convergence | The amount of convergence required to view binocularly an object 1 meter distant and exerting 1 diopter of accommodation. Synonym: unit of ocular convergence. (05 Mar 2000) |
| filar micrometre ocular | <microscopy> A micrometre ocular with crossed lines which can be simultaneously focused in and moved across the field by means of a micrometre screw. The amount of displacement can be read in 0.01 steps on the micrometre drum head. This makes a very delicate measuring device, since calibration of the micrometre scale by means of a stage micrometre gives values for each interval on the drum head which are much less than the resolving power of the highest-aperture objectives. (05 Aug 1998) |
| fixational ocular movement | Rotation of the eyes during voluntary fixation on an object; tremors, flicks, and drifts occur. (05 Mar 2000) |
| fixation, ocular | The direction of the gaze so that the visual image of the object falls on the fovea centralis of the retina, the area of the most acute vision. (12 Dec 1998) |
| Frenkel's anterior ocular traumatic syndrome | <syndrome> An obsolete term for traumatic iridoplegia, which consists of mydriasis, hyphema, small iris tears near the pupil, discrete punctate opacities of the lens, and occasionally iridodialysis. (05 Mar 2000) |
| abdominal muscles | A large group of muscles in the front of the abdomen that assists in the regular breathing movement and supports the muscles of the spine while lifting and keeping abdominal organs such as the intestines in place. (12 Dec 1998) |
| antagonistic muscles | Those having an opposite function, the contraction of one having the potential, in theory, to "neutralise" that of the other. (05 Mar 2000) |
| anterior cervical intertransversarii muscles | Origin, anterior tubercle of cervical transverse process; insertion, anterior tubercle of next superior transverse process; action, abducts cervical vertebrae; nerve supply, ventral branch of cervical nerves. Synonym: musculi intertransversarii anteriores cervicis, anterior cervical intertransverse muscles. (05 Mar 2000) |
| anterior cervical intertransverse muscles | Origin, anterior tubercle of cervical transverse process; insertion, anterior tubercle of next superior transverse process; action, abducts cervical vertebrae; nerve supply, ventral branch of cervical nerves. Synonym: musculi intertransversarii anteriores cervicis, anterior cervical intertransverse muscles. (05 Mar 2000) |
| antigravity muscles | The muscle's that maintain the posture characteristic of a given animal species. In most mammals they are the extensor muscle's. (05 Mar 2000) |
