ocular
| ocular | 1. Of, pertaining to or affecting the eye. 2. Eyepiece. Origin: L. Ocularis, from oculus = eye (18 Nov 1997) |
|---|---|
| ocular albinism | The absence of pigment chiefly in the iris, choroid, and retinal pigment epithelium with deafness; X-linked inheritance. (05 Mar 2000) |
| ocular bobbing | Sudden conjugate downward deviation of the eyes with a slow return to the normal position; seen in some comatose patients who have bilateral hemisphere lesions. (05 Mar 2000) |
| ocular cone | The cone of light in the interior of the eyeball with the base formed by the rays entering through the pupil and the apex focused on the retina. (05 Mar 2000) |
| ocular crisis | Sudden and severe pain in the eyes. (05 Mar 2000) |
| ocular cup | The double-walled cup formed by the invagination of the embryonic optic vesicle; its inner component becomes the sensory layer of the retina, its outer layer, the pigment layer. Synonym: caliculus ophthalmicus, ocular cup. (05 Mar 2000) |
| ocular dysmetria | Abnormality of ocular movements in which the eyes overshoot on attempting to fixate an object. (05 Mar 2000) |
| ocular flutter | A spontaneous, brief, intermittent, horizontal oscillation of the eyes occurring during fixation; it often coexists with ocular dysmetria in cerebellar syndromes. (05 Mar 2000) |
| ocular humor | One of the two humor's of the eye: aqueous and vitreous. (05 Mar 2000) |
| ocular hypertelorism | <clinical sign, ophthalmology> Extreme width between the eyes, mental retardation may be associated. (13 Nov 1997) |
| ocular hypertension | A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma. (12 Dec 1998) |
| ocular hypotension | Abnormally low intraocular pressure often related to chronic inflammation (uveitis). (12 Dec 1998) |
| ocular larva migrans | Visceral larva migrans involving the eyes, primarily of older children; clinical symptoms include decreased visual acuity and strabismus. (05 Mar 2000) |
| ocular lens | <physics> The lens nearest the eye in any ocular. (05 Aug 1998) |
| ocular lymphomatosis | See: avian lymphomatosis. (05 Mar 2000) |
| accommodation, ocular | The dioptric adjustment of the eye (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. It is the effecting of refractive changes by changes in the shape of the crystalline lens. Loosely, it refers to ocular adjustments for vision at various distances. (12 Dec 1998) |
|---|---|
| adaptation, ocular | The adjustment of the eye to variations in the intensity of light. Light adaptation is the adjustment of the eye when the light threshold is increased; dark adaptation when the light is greatly reduced. (12 Dec 1998) |
| albinism, ocular | Albinism affecting the eye in which pigment of the hair and skin is normal or only slightly diluted. The classic type is x-linked (nettleship-falls), but an autosomal recessive form also exists. Ocular abnormalities may include reduced pigmentation of the iris, nystagmus, photophobia, strabismus, and decreased visual acuity. (12 Dec 1998) |
| anterior ocular segment | That portion of the eye comprising the cornea, iris, lens, and their associated chambers and adnexa. (05 Mar 2000) |
| cardinal ocular movements | Eye rotations to the right and left, upward to the right and left, and downward to the right and left, to diagnose positions of gaze. (05 Mar 2000) |
| Ramsden's ocular | An eyepiece of a microscope, consisting of two planoconvex lenses with convexities turned to each other. (05 Mar 2000) |
| vestibular ocular reflex | <clinical sign> Reflex movement of the eyes in the opposite direction to that which the head is moved, e.g., the eyes being lowered as the head is raised, and the reverse (Cantelli's sign); an indication of functional integrity of the brainstem tegmental pathways and cranial nerves involved in eye movement. Synonym: vestibular ocular reflex. (05 Mar 2000) |
| reflex, vestibulo-ocular | A reflex wherein impulses are conveyed from the cupulas of the saemicircular canals and from the otolithic membrane of the saccule and utricle via the vestibular nuclei of the brainstem and the median longitudinal fasciculus to the oculomotor nerve nuclei. It functions to maintain a stable retinal image during head rotation by generating appropriate compensatory eye movements. (12 Dec 1998) |
| refraction, ocular | Refraction of light effected by the media of the eye. It also includes the determination of the refractive state and refractive correction. (12 Dec 1998) |
| goniometre ocular | <microscopy> A special type of ocular fitted with crosslines and a graduated head which rotates the crosslines to facilitate the measuring of angles, as in crystallography. (05 Aug 1998) |
| retro-ocular | <anatomy> Behind the pons. Origin: L. Bulbus = bulb (18 Nov 1997) |
| cogwheel ocular movements | Loose, jerky ocular rotations replacing smooth following rotations. (05 Mar 2000) |
| compensating ocular | An ocular that compensates and corrects for the effects of chromatic aberration in the objective. (05 Mar 2000) |
| wide field ocular | An ocular that gives a larger than usual field of view and a high eyepoint. (05 Mar 2000) |
| musculoskeletal, neural, and ocular physiology | Activities and functions of the musculoskeletal system, the nervous system, and the eye and their parts. (12 Dec 1998) |
