  2. Exotropia - Wikipedia

    en.wikipedia.org/wiki/Exotropia

    Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence of poor vision in one eye.

    en.wikipedia.org/wiki/Exophoria

    Exophoria. Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward. [ 1] During examination, when the eyes are dissociated, the visual axes will appear to diverge away from one another. [ 2] The axis deviation in exophoria is usually mild compared with that of exotropia .

    Thus, when the eyes are misaligned, two different objects will be perceived as superimposed in the same space. This phenomenon is known as 'visual confusion'. [20] The brain naturally guards against double vision. In an attempt to avoid double vision, the brain can sometimes ignore the image from one eye, a process known as suppression. The ...

    Treatment. Eyeglasses, contact lenses, refractive surgeries, IOL implantation [ 2] Frequency. ~7.5% (US) [ 5] Far-sightedness, also known as long-sightedness, hypermetropia, and hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred.

  8. Oscillopsia - Wikipedia

    en.wikipedia.org/wiki/Oscillopsia

    Oscillopsia is a visual disturbance in which objects in the visual field appear to oscillate. The severity of the effect may range from a mild blurring to rapid and periodic jumping. [ 1] Oscillopsia is an incapacitating condition experienced by many patients with neurological disorders. [ 2] It may be the result of ocular instability occurring ...

    Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit.

Complete or partial dislocation from the orbit is also possible from trauma or ...
