| halo melanoma | <tumour> A rare condition in which a melanoma is surrounded by an irregular area of depigmentation. (05 Mar 2000) |
|---|---|
| Harding-Passey melanoma | <tumour> A melanin-forming tumour that arose spontaneously in a non-inbred mouse, and that is transplantable to mice of many strains but does not ordinarily metastasize. (05 Mar 2000) |
| Xiphophorus melanoma receptor kinase | <enzyme> Growth factor receptor protein with an extracellular ligand binding domain and an intracellular catalytic domain Registry number: EC 2.7.1.- Synonym: xmrk protein (26 Jun 1999) |
| nodular melanoma | <tumour> Primary cutaneous melanoma characterised by dermal invasion extending to the lateral margins of epidermal involvement or ulceration. (05 Mar 2000) |
| subungual melanoma | <tumour> A melanoma beginning in the skin at the border of or beneath the nail. Synonym: melanotic whitlow. (05 Mar 2000) |
| superficial spreading melanoma | <tumour> Primary cutaneous melanoma characterised by intraepidermal growth extending laterally beyond the site of dermal invasion. (05 Mar 2000) |
| desmoplastic malignant melanoma | <tumour> A melanoma with marked fibrosis surrounding atypical spindle-shaped melanocytes in the dermis. (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) |
