| AION | anterior ischemic optic neuropathy |
| AOT | accessory optic tract; Anderson Olsson table; anodal opening tetanus; Association of Occupational Th... |
| BOR | basal optic root; before time of operation; bowels open regularly; branchio-oto-renal [syndrome] |

| fallopian neuritis | Paralysis of the facial muscles, usually unilateral, due to either a lesion involving the nucleus or the facial nerve peripheral to the nucleus (peripheral facial paralysis) or a supranuclear lesion in the cerebrum or upper brainstem (central facial paralysis). With latter, facial weakness is usually partial and the upper portion of the face is relatively spared, due to bilateral cortical connections. (12 Dec 1998) |

| axis, optic | <microscopy> The direction, or directions in an anisotropic crystal along which light is not doubly refracted. (05 Aug 1998) |
| ganglionic layer of optic nerve | <anatomy, nerve> The inner layer of multipolar neurons in the retina consisting of the relatively large neurons that give rise to the fibres of the optic nerve. Synonym: stratum ganglionare nervi optici. (05 Mar 2000) |
| vascular circle of optic nerve | <anatomy, nerve> A network of branches of the short ciliary arteries on the sclera around the point of entrance of the optic nerve.

| glioma of optic chiasm | A slow-growing tumour, usually an astrocytoma, of the optic chiasm in children. (05 Mar 2000) |

| septo-optic dysplasia | <radiology> Blindness, hypopituitarism, hypoplastic optic nerves, optic chiasm rotated 90 degrees, bulbous 3rd ventricle, CT findings: absent septum pellucidum, small optic nerves (12 Dec 1998) |
