The main symptom is loss of vision, with colors appearing subtly washed out in the affected eye. A pale disc is characteristic of long-standing optic neuropathy. In many cases, only one eye is affected and a person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye.
"Her eyes were glistening jewels". Metaphor may also be used for any rhetorical figures of speech that achieve their effects via association, comparison or resemblance. In this broader sense, antithesis, hyperbole, metonymy and simile would all be considered types of metaphor. Aristotle used both this sense and the regular, current sense above. [1]
Both the eyes and legs are still of the normal colour. Leucism (/ ˈ l uː s ɪ z əm,-k ɪ z-/) [2] [3] [4] is a wide variety of conditions that result in partial loss of pigmentation in an animal—causing white, pale, or patchy coloration of the skin, hair, feathers, scales, or cuticles, but not the eyes. [4] It is occasionally spelled leukism.
Dry eye syndrome can lead to blurred vision, instability of the tear film, increased risk of damage to the ocular surface such as scarring of the cornea, and changes in the eye including the neurosensory system. [2] [6] Dry eye occurs when either the eye does not produce enough tears or when the tears evaporate too quickly. [2]
Oculocutaneous albinism (OCA): A group of inherited disorders that affect melanin production, causing pale skin, hair, and eyes. [11] Griscelli syndrome: A rare genetic condition characterized by pigmentary dilution and immunodeficiency. [12] Chediak-Higashi syndrome: This genetic disorder results in pigmentary abnormalities and immune system ...
Eye conditions common in albinism include: Nystagmus, irregular rapid movement of the eyes back and forth, or in circular motion. [8] Amblyopia, decrease in acuity of one or both eyes due to poor transmission to the brain, often due to other conditions such as strabismus. [8] Optic nerve hypoplasia, underdevelopment of the optic nerve.
Choroidal nevus (plural: nevi) is a type of eye neoplasm that is classified under choroidal tumors as a type of benign (non-cancerous) melanocytic tumor. [1] A choroidal nevus can be described as an unambiguous pigmented blue or green-gray choroidal lesion, found at the front of the eye, around the iris, [2] or the rear end of the eye.
These processes cause the typical symptoms of fainting: pale skin, rapid breathing, nausea, and weakness of the limbs, particularly of the legs. [3] If the ischemia is intense or prolonged, limb weakness progresses to collapse. [3] The weakness of the legs causes most people to sit or lie down if there is time to do so.
