| hypermetropia | Farsightedness or hyperopia occurs when a refractive error in which light rays entering the eye are focused behind the retina. This condition is easily corrected with corrective lenses or contact lenses. (27 Sep 1997) |
|---|---|
| index hypermetropia | Hypermetropia arising from decreased refractivity of the lens. Origin: hyper-+ G. Metron, measure, + ops, eye (05 Mar 2000) |
| axial | <anatomy> Position as it relates to the CNS. Intra-axial is within the CNS, extra-axial is outside the CNS. (16 Dec 1997) |
| axial ametropia | That resulting from a shortening or lengthening of the eyeball on the optic axis, causing hyperopia or myopia, respectively. (05 Mar 2000) |
| axial aneurysm | An aneurysm involving the entire circumference of a blood vessel. (05 Mar 2000) |
| axial angle | An angle formed by two surfaces of a body, the line of union of which is parallel with its axis; the axial angle's of a tooth are the distobuccal, distolabial, distolingual, mesiobuccal, mesiolabial, and mesiolingual. (05 Mar 2000) |
