  2. Corneal neovascularization - Wikipedia

    en.wikipedia.org/wiki/Corneal_neovascularization

    Corneal tissue is avascular in nature and the presence of vascularization, which can be deep or superficial, is always pathologically related. [ 2 ] Corneal neovascularization is a sight-threatening condition that can be caused by inflammation related to infection, chemical injury, autoimmune conditions, immune hypersensitivity , post- corneal ...

  3. Effects of long-term contact lens wear on the cornea - Wikipedia

    en.wikipedia.org/wiki/Effects_of_long-term...

    Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake. . Other structural changes may include the formation of epithelial vacuoles and microcysts (containing cellular debris), corneal neovascularization, as well as the emergence of polymegethism in the corneal endoth

    en.wikipedia.org/wiki/Neovascularization

    Neovascularization is the natural formation of new blood vessels (neo-+ vascular + -ization), usually in the form of functional microvascular networks, capable of perfusion by red blood cells, that form to serve as collateral circulation in response to local poor perfusion or ischemia.

    Corneal neovascularization – excessive ingrowth of blood vessels from the limbal vascular plexus into the cornea, caused by deprivation of oxygen from the air. Fuchs' dystrophy – cloudy morning vision. Keratitis – inflammation of the cornea. Keratoconus – a degenerative disease, the cornea thins and changes shape to be more like a cone.

    Blindness can happen as a complication of corneal ulceration. This more commonly occurs in malnourished children with vitamin A deficiency, according to the American Academy of Ophthalmology.

  8. Pannus - Wikipedia

    en.wikipedia.org/wiki/Pannus

    In normal individuals, the cornea is avascular. Chronic local hypoxia (such as that occurring with overuse of contact lenses) or inflammation may lead to peripheral corneal vascularization, or pannus. Pannus may also develop in diseases of the corneal stem cells, such as aniridia. It is often resolved by peritomy.

  9. Corneal limbus - Wikipedia

    en.wikipedia.org/wiki/Corneal_limbus

    The corneal limbus manifests as a dark ring around the iris. Its prominence varies by individual. The corneal limbus is the border between the cornea and the sclera. [1] It is highly vascularized. [1] The corneal limbus' responsibilities include protection, healing, and controlling eye pressure.
