| accommodative strabismus | Strabismus in which the severity of deviation varies with accommodation. (05 Mar 2000) |
|---|
| accommodative | Relating to accommodation. (05 Mar 2000) |
|---|---|
| accommodative asthenopia | Asthenopia due to errors of refraction and excessive contraction of the ciliary muscle. (05 Mar 2000) |
| accommodative convergence | The meter angle of convergence expressed in diopters; equal to the product of the meter angles of convergence times the interpupillary distance measured in centimeters. (05 Mar 2000) |
| accommodative convergence-accommodation ratio | The amount of convergence (measured in prism diopters of convergence) divided by the amount of accommodation (measured in diopters) required to direct both eyes upon an object. (05 Mar 2000) |
| refractive accommodative esotropia | That type of esotropia eliminated by correction of hypermetropic refractive error. (05 Mar 2000) |
| nonrefractive accommodative esotropia | That type of esotropia in which an abnormality of the accommodative-convergence mechanism is not eliminated by correction of refractive error. (05 Mar 2000) |
| alternate day strabismus | Periodic convergent strabismus often occurring every 48 hours. Synonym: alternate day strabismus. (05 Mar 2000) |
| alternating strabismus | A form of strabismus in which either eye fixes. (05 Mar 2000) |
| A-pattern strabismus | Strabismus in which esotropia is more marked in looking upward than downward, strabismus in which exotropia is more marked on looking downward than upward. Synonym: A-pattern strabismus. (05 Mar 2000) |
| arteriovenous strabismus syndrome | <syndrome> Strabismus in which the angle of deviation is more marked on looking upward or downward. See: A-esotropia, V-esotropia, A-exotropia, V-exotropia. (05 Mar 2000) |
| A-strabismus | Strabismus in which esotropia is more marked in looking upward than downward, strabismus in which exotropia is more marked on looking downward than upward. Synonym: A-pattern strabismus. (05 Mar 2000) |
| A-V strabismus syndrome | <syndrome> Strabismus in which the angle of deviation is more marked on looking upward or downward. See: A-esotropia, V-esotropia, A-exotropia, V-exotropia. (05 Mar 2000) |
| manifest strabismus | Evident deviation of one eye or the other; may be alternating or monocular. (05 Mar 2000) |
| paralytic strabismus | Strabismus due to weakness of an ocular muscle or muscles. Synonym: incomitant strabismus. (05 Mar 2000) |
| vertical strabismus | A form of strabismus in which the visual axis of one eye deviates upward (s. Sursum vergens) or downward (s. Deorsum vergens). (05 Mar 2000) |
