  • Voluntary propulsion of eyeball

    The ability to voluntarily cause the globe of the eye to protrude by as much as 10 mm (0.4 in). This is not harmful to the eye or visual acuity.  

  • Trophic ulceration of eye

    A noninfectious ulceration of the corneal epithelium of the eye due to repeated trauma.  

  • Sympathizing eye

    In sympathetic ophthalmia, the uninjured eye, which reacts to the pathological process in the injured eye.  

  • Squinting eye

    An eye that deviates from the object of fixation in strabismus.  

  • Light-adapted eye

    An eye that has become adjusted to viewing objects in bright light; one adapted for phototic, or cone, vision. In this type of eye, most rhodopsin has been broken down.  

  • Fixating eye

    In strabismus, the eye that is directed toward the object of vision.  

  • Exciting eye

    In sympathetic ophthalmia, the damaged eye, which is the source of sympathogenic influences.  

  • Dominant eye

    The eye to which a person unconsciously gives preference as a source of stimuli for visual sensations. The dominant eye is usually used in sighting down a gun or looking through a monocular microscope.  

  • Eye deviation

    In eye muscle imbalance and “crossed eyes,” the abnormal visual axis of the eye that is not aligned.  

  • Dark-adapted eye

    An eye that has become adjusted for viewing objects in dim light; one adapted for scotopic, or rod, vision. Dark adaptation depends on the regeneration of rhodopsin, the light sensitive glycoprotein in the rods of the eye.
