| near point | That point in conjugate focus with the retina when the eye exerts maximal accommodation. Synonym: punctum proximum. (05 Mar 2000) |
|---|---|
| near point of convergence | The point to which the visual lines are directed when convergence is at its maximum. (05 Mar 2000) |
| near point of the eye | <ophthalmology> The nearest point to the entrance of the pupil of the normal eye at which focus is attained without strain, 10 inches (250 mm) is the generally accepted distance. In very young people and in those with myopia, this distance is less. The near point recedes with age, possibly even causing farsighted condition,. (05 Aug 1998) |
| near reaction | The pupillary constriction associated with a near vision effort, i.e., with accommodation and convergence. (05 Mar 2000) |
| near reflex | Pupillary constriction with a near vision effort, with ocular convergence, or with accommodation; an associated reaction, not a true reflex. (05 Mar 2000) |
| near sight | <ophthalmology> That error of refraction in which rays of light entering the eye parallel to the optic axis are brought to a focus in front of the retina, as a result of the eyeball being too long from front to back (axial myopia) or of an increased strength in refractive power of the media of the eye (index myopia). Also called nearsightedness, because the near point is less distant than it is in emmetropia with an equal amplitude of accommodation. Origin: Gr. Myein = to shut (18 Nov 1997) |
| near-total thyroidectomy | Removal of nearly all of each thyroid lobe leaving unresected only a small portion of gland adjacent to the entrance of the recurrent laryngeal nerve into the larynx. (05 Mar 2000) |
| far-and-near suture | A suture utilizing alternate near and far stitches, used to approximate fascial edges. (05 Mar 2000) |
| light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
