| angle of antetorsion | <orthopaedics> The angle formed by a line drawn through the centre of the long axis of the neck of the femur meeting a line drawn in the transverse axis of the condyles, when the bone is viewed from above, looking straight down through the head of the femur. It is used to illustrate the normal degree of anteversion about 12 |

It is used to illustrate the normal degree of anteversion about 12 |
| angle of aperture | <ophthalmology, optics> The angle formed by lines drawn from the ends of the diameter of a lens to its point of focus. See: angular aperture. (05 Mar 2000) |
| angle of convergence | <optics> The angle that the visual axis makes with the median line when a near object is viewed. (05 Mar 2000) |
| angle of declination | An obsolete term for angle of anteversion. (05 Mar 2000) |
| angle of depression | <orthopaedics> The angle formed by the meeting of a line drawn through the shaft of the femur with one passing through the long axis of the femoral neck; normally it is about 127 |
| angle of deviation | <optics> In a prism, the sum of the angle's of incidence and emergence minus the apical angle of a prism, in optics, angle of refraction, in strabismus, angle of anomaly. (05 Mar 2000) |
| angle of eccentricity | <ophthalmology> In strabismus, the angle between the line of fixation and the line of normal foveal fixation. (05 Mar 2000) |
| angle of emergence | <optics> The angle formed by a light ray emerging from the second surface of a prism and a line parallel to the incident ray. Compare: angle of deviation. (05 Mar 2000) |

| angle of Fuchs | <ophthalmology> A crevice between the ciliary and pupillary zones of the iris formed by atrophy of superficial layers of the iris in the pupillary zone. (05 Mar 2000) |
| angle of incidence | <optics> The angle that a ray entering a refracting medium makes with a line drawn perpendicular to the surface of this medium, the angle that a ray striking a reflecting surface makes with a line perpendicular to this surface. Synonym: incident angle. (05 Mar 2000) |
| angle of inclination | <orthopaedics> The angle formed by the meeting of a line drawn through the shaft of the femur with one passing through the long axis of the femoral neck; normally it is about 127 |
| angle of iris | The acute angle between the iris and the cornea at the periphery of the anterior chamber of the eye. Synonym: angulus iridocornealis, angle of iris, angulus iridis, filtration angle. (05 Mar 2000) |
| angle of jaw | <anatomy> The angle formed by the lower margin of the body and the posterior margin of the ramus of the mandible. Synonym: angulus mandibulae, angle of jaw. (05 Mar 2000) |
