  2. Diplopia - Wikipedia

    en.wikipedia.org/wiki/Diplopia

    Diplopia can also occur when viewing with only one eye; this is called monocular diplopia, or where the patient perceives more than two images, monocular polyopia. While serious causes rarely may be behind monocular diplopia symptoms, this is much less often the case than with binocular diplopia. [ 15 ]

  3. Cerebral polyopia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_polyopia

    Cerebral diplopia or polyopia describes seeing two or more images arranged in ordered rows, columns, or diagonals after fixation on a stimulus. [ 1 ] [ 2 ] The polyopic images occur monocular bilaterally (one eye open on both sides) and binocularly (both eyes open), differentiating it from ocular diplopia or polyopia.

  4. Positive visual phenomena - Wikipedia

    en.wikipedia.org/wiki/Positive_visual_phenomena

    A rare illusion characterized by monocular diplopia, excluding refractive abnormalities. When this occurs at the cortical level, this pathophysiology is not well understood. Dysmetropsia (Micro/Macropsia)

  5. Suppression (eye) - Wikipedia

    en.wikipedia.org/wiki/Suppression_(eye)

    "Suppression is familiar to anyone who has trained himself to look through a monocular microscope, sight a gun, or do any other strictly one-eye task, with the other eye open. The scene simply disappears for the suppressed eye." [1] Suppression is frequent in children with anisometropia or strabismus or both. For instance, children with ...

  6. Monocular vision - Wikipedia

    en.wikipedia.org/wiki/Monocular_vision

    Monocular vision is known as seeing and using only one eye in the human species. Depth perception in monocular vision is reduced compared to binocular vision, but still is active primarily due to accommodation of the eye and motion parallax. The word monocular comes from the Greek root, mono for single, and the Latin root, oculus for eye.

  7. Aberrations of the eye - Wikipedia

    en.wikipedia.org/wiki/Aberrations_of_the_eye

    The appearance of visual complaints such as halos, glare and monocular diplopia after corneal refractive surgery has long been correlated with the induction of optical aberrations. Several mechanisms may explain the increase in the amount of higher-order aberrations with conventional excimer laser refractive procedures: a change in corneal ...

  8. Worth 4 dot test - Wikipedia

    en.wikipedia.org/wiki/Worth_4_dot_test

    Good starting point when investigating the nature of diplopia i.e. to find manifest, intermittent, crossed or uncrossed diplopia; It is less dissociative than a cover test [1] Can be used to determine if a patient will demonstrate binocular single vision with corrective prism or head posture [1] Relatively easy to record and interpret the results

  9. Optical phenomenon - Wikipedia

    en.wikipedia.org/wiki/Optical_phenomenon

    Monocular diplopia (or polyplopia) from reflections at boundaries between the various ocular media; Phosphenes from stimulation other than by light (e.g., mechanical, electrical) of the rod cells and cones of the eye or of other neurons of the visual system; Purkinje images.
