  2. Ocular prosthesis - Wikipedia

    en.wikipedia.org/wiki/Ocular_prosthesis

    Human ocular prosthesis of brown color. Cat with an ocular prosthesis. An ocular prosthesis, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration.

  3. Pseudoexfoliation syndrome - Wikipedia

    en.wikipedia.org/wiki/Pseudoexfoliation_syndrome

    Its prevalence in different human populations varies; for example, it is prevalent in Scandinavia. [2] The buildup of protein clumps can block normal drainage of the eye fluid called the aqueous humor and can cause, in turn, a buildup of pressure leading to glaucoma and loss of vision [3] (pseudoexfoliation glaucoma, exfoliation glaucoma). As ...

  4. Heterochromia iridum - Wikipedia

    en.wikipedia.org/wiki/Heterochromia_iridum

    The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic). [3] In humans, an increase of melanin production in the eyes indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia. The term is derived from Ancient Greek: ἕτερος, héteros "different" and χρῶμα, chrôma "color ...

  5. Enucleation of the eye - Wikipedia

    en.wikipedia.org/wiki/Enucleation_of_the_eye

    To avoid a sunken appearance to the eye socket, an implant approximating this volume can be placed into the space of the removed eye, secured, and covered with Tenon's capsule and conjunctiva. [7] Implants can be made of many materials with the most common being hydroxylapatite , metal alloy, [ 8 ] acrylic, or glass.

  6. Leukocoria - Wikipedia

    en.wikipedia.org/wiki/Leukocoria

    On photographs taken using a flash, instead of the familiar red-eye effect, leukocoria can cause a bright white reflection in an affected eye. Leukocoria may appear also in low indirect light, similar to eyeshine. Leukocoria can be detected by a routine eye exam (see Ophthalmoscopy). For screening purposes, the red reflex test is used.

  7. Eye color - Wikipedia

    en.wikipedia.org/wiki/Eye_color

    There is evidence that as many as 16 different genes could be responsible for eye color in humans; however, the main two genes associated with eye color variation are OCA2 and HERC2, and both are localized in chromosome 15. [10] The gene OCA2 (OMIM: 203200), when in a variant form, causes the pink eye color and hypopigmentation common in human ...

  9. Monochromacy - Wikipedia

    en.wikipedia.org/wiki/Monochromacy

    Human vision relies on a duplex retina, comprising two types of photoreceptor cells. Rods are primarily responsible for dim-light scotopic vision and cones are primarily responsible for day-light photopic vision. For all known vertebrates, scotopic vision is monochromatic, since there is typically only one class of rod cell.
