| manifest strabismus | Evident deviation of one eye or the other; may be alternating or monocular. (05 Mar 2000) |

| mechanical strabismus | Strabismus due to restriction of action of the ocular muscle within the orbit. (05 Mar 2000) |
| monocular strabismus | An obsolete term for strabismus in which one eye habitually deviates. (05 Mar 2000) |

| strabismus | <clinical sign> A deviation of the eye which the patient cannot overcome. The visual axes assume a position relative to each other different from that required by the physiological conditions. The various forms of strabismus are spoken of as tropias, their direction being indicated by the appropriate prefix, as cyclo tropia, esotropia, exotropia, hypertropia and hypotropia. Also called cast, heterotropia, manifest deviation and squint. Origin: Gr. Strabismos = a squinting (18 Nov 1997) |
| strabismus deorsum vergens | An obsolete term for vertical strabismus in which the visual axis of one eye deviates downward. (05 Mar 2000) |
| strabismus sursum vergens | An obsolete term for a vertical strabismus in which the visual axis of one eye deviates upward. (05 Mar 2000) |
| divergent strabismus | <clinical sign> The outward or temporal deviation of an eye. (27 Sep 1997) |
