  2. Scintillating scotoma - Wikipedia

    en.wikipedia.org/wiki/Scintillating_scotoma

    Causes. Scintillating scotomas are most commonly caused by cortical spreading depression, a pattern of changes in the behavior of nerves in the brain during a migraine. Migraines, in turn, may be caused by genetic influences and hormones.

  3. Homonymous hemianopsia - Wikipedia

    en.wikipedia.org/wiki/Homonymous_hemianopsia

    Homonymous hemianopsia occurs because the right half of the brain has visual pathways for the left hemifield of both eyes, and the left half of the brain has visual pathways for the right hemifield of both eyes. When one of these pathways is damaged, the corresponding visual field is lost.

  4. Sixth nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Sixth_nerve_palsy

    These slim flexible plastic prisms can be attached to the patient's glasses, or to plano glasses if the patient has no refractive error, and serve to compensate for the inward misalignment of the affected eye. Unfortunately, the prism only correct for a fixed degree of misalignment and, because the affected individual's degree of misalignment ...

  5. Micropsia - Wikipedia

    en.wikipedia.org/wiki/Micropsia

    Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous retinopathy), by changes in the brain (such as from traumatic brain injury ...

  6. Metamorphopsia - Wikipedia

    en.wikipedia.org/wiki/Metamorphopsia

    Causes of metamorphopsia. Metamorphopsia can be a symptom of a number of eye disorders involving the retina or macula. Some of these conditions include the following: Age-related macular degeneration; Epiretinal membrane and vitreomacular traction; Posterior vitreous detachment; Macular hole; Diagnosis

  7. Hypertropia - Wikipedia

    en.wikipedia.org/wiki/Hypertropia

    cyclotropia, a cyclotorsional deviation of the eyes (rotation around the visual axis), particularly when the root cause is an oblique muscle paresis causing the hypertropia. Causes. Hypertropia may be either congenital or acquired, and misalignment is due to imbalance in extraocular muscle function.

  8. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions.

  9. Strabismus - Wikipedia

    en.wikipedia.org/wiki/Strabismus

    If a great difference in clarity occurs between the images from the right and left eyes, input may be insufficient to correctly reposition the eyes. Other causes of a visual difference between right and left eyes, such as asymmetrical cataracts, refractive error, or other eye disease, can also cause or worsen strabismus. [page needed]

  10. Photopsia - Wikipedia

    en.wikipedia.org/wiki/Photopsia

    Causes. Several conditions affecting the eyes can cause photopsia to occur. The underlying condition must be identified and treated to resolve the symptoms. Peripheral (posterior) vitreous detachment. Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age.

  11. Ocular myasthenia - Wikipedia

    en.wikipedia.org/wiki/Ocular_myasthenia

    Also, plastic prisms (Fresnel prisms) can be attached to eyeglasses of a diplopic patient, allowing for alignment of vision from both eyes in the affected direction, but are often problematic if the degree of muscle weakness, and therefore ocular misalignment, fluctuates frequently. Epidemiology
