Rubeosis iridis. Rubeosis iridis. Other names. Neovascularization of the iris. Specialty. Ophthalmology. Rubeosis iridis is a medical condition of the iris of the eye in which new abnormal blood vessels (formed by neovascularization) are found on the surface of the iris. [1]
Uveitis–glaucoma–hyphaema (UGH) syndrome, also known as Ellingson syndrome, is a complication of cataract surgery, caused by intraocular lens subluxation or dislocation. The chafing of mispositioned intraocular lens over iris, ciliary body or iridocorneal angle cause elevated intraocular pressure (IOP) anterior uveitis and hyphema.
Specialty. Ophthalmology. Hyphema is the medical condition of bleeding in the anterior chamber of the eye between the iris and the cornea. [1] People usually first notice a loss or decrease in vision. [1] The eye may also appear to have a reddish tinge, or it may appear as a small pool of blood at the bottom of the iris in the cornea.
Ophthalmology. Corneal neovascularization (CNV) is the in-growth of new blood vessels from the pericorneal plexus into avascular corneal tissue as a result of oxygen deprivation. [1] Maintaining avascularity of the corneal stroma is an important aspect of healthy corneal physiology as it is required for corneal transparency and optimal vision.
Corneal opacification is a term used when the human cornea loses its transparency. The term corneal opacity is used particularly for the loss of transparency of cornea due to scarring. Transparency of the cornea is dependent on the uniform diameter and the regular spacing and arrangement of the collagen fibrils within the stroma.
Medical genetics. Aniridia is the absence of the iris, a muscular structure that opens and closes the pupil to allow light into the eye. It is also responsible for eye color. Without it, the central eye appears all black. It can be congenital, in which both eyes are usually involved, or caused by a penetrant injury. [1]
Uveitis. Uveitis (/ ˌjuːvi.aɪtɪs /) is inflammation of the uvea, the pigmented layer of the eye between the inner retina and the outer fibrous layer composed of the sclera and cornea. [1] The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid.
Ocular synechia is an eye condition where the iris adheres to either the cornea (i.e. anterior synechia) or lens (i.e. posterior synechia). [1] Synechiae can be caused by ocular trauma, iritis or iridocyclitis and may lead to certain types of glaucoma.
