| olfactory angle | The angle formed by the plane of the lamina cribrosa and the basicranial axis. (05 Mar 2000) |

| open-angle glaucoma | <ophthalmology> A disorder which is characterised by increased pressure within the eyeball. This occurs secondary to the chronic blockage of normal fluid circulation within the eye. Increased pressure within the eye can cause damage to the optic nerve and eventual blindness. Glaucoma is the leading cause of blindness. Symptoms include decreased vision, halos around lights (worse at night) and mild chronic headaches. Treatment is generally with beta-blocker eyedrops. Synonym: chronic glaucoma, compensated glaucoma, simple glaucoma, glaucoma simplex. (22 Sep 2002) |
| ophryospinal angle | See: Jacquart's facial angle. (05 Mar 2000) |
| tentorial angle | The angle made by the plane of the tentorium and the basicranial axis. (05 Mar 2000) |
| Topinard's facial angle | See: Jacquart's facial angle. (05 Mar 2000) |
| epigastric angle | The angle formed by the xiphoid process with the body of the sternum. (05 Mar 2000) |
| ethmoid angle | The angle made by the plane of the cribriform plate of the ethmoid bone extended to meet the basicranial axis. (05 Mar 2000) |
| Jacquart's facial angle | A facial angle with the intersection always at the nasal spine point; additional variation uses the supraorbital point instead of the glabella, and this latter version is also known as ophryospinal facial angle or Topinard's facial angle. (05 Mar 2000) |
| extinction angle | <microscopy> The angle between the nearer vibration direction and a prominent direction of the crystal. It never exceeds 45 degrees (05 Aug 1998) |
| facial angle | Any of several variously named and variously defined anatomical angle's that have been used to quantify facial protrusion, in dentistry, the angle formed by the intersection of the orbitomeatal (Frankfort) plane with the nasion-pogonion line (inner lower angle), which establishes the anteroposterior relation of the mandible to the upper face at the orbitomeatal plane. Synonym: Frankfort-mandibular incisor angle. (05 Mar 2000) |
| kappa angle | The angle between the pupillary axis and the visual axis; it is positive when the pupillary axis is nasal to the visual axis, and negative when the pupillary axis is temporal to the visual axis. (05 Mar 2000) |
| y-angle | In craniometry, the angle at the inion formed by lines drawn from the hormion and the lambda. Synonym: hypsiloid angle. (05 Mar 2000) |
| filtration angle | 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) |
| flip angle | In a magnetic resonance imaging sequence, the rotation of the average axis of the protons induced by radiofrequency signals; low angles are used in rapid-imaging sequences and to show a signal from flowing blood. (05 Mar 2000) |
| lateral angle of eye | The angle formed by the junction of the lateral parts of the upper and lower eyelids. Synonym: angulus oculi lateralis, angulus oculi temporalis, external canthus, lateral canthus. (05 Mar 2000) |
