	Iris (anatomy) - Wikipedia, the free encyclopedia
		Just in front of the root of the iris is the region through which the aqueous humour constantly drains out of the eye, with the result that diseases of the iris often have important effects on intraocular pressure, and indirectly on vision.
		The collarette is the region of the iris separating the pupillary portion from the ciliary portion.
		Iris color is a highly complex phenomenon consisting of the combined effects of texture, pigmentation, fibrous tissue and blood vessels within the iris stroma, which together make up an individual's epigenetic constitution.

	Iris recognition - Wikipedia, the free encyclopedia
		Iris recognition is a method of biometric identification based on high-resolution images of the irides of an individual's eyes.
		Iris scanning is a relatively new technology and is incompatible with the very substantial investment that the law enforcement and immigration authorities of some countries have already made into finger-print recognition.
		Iris recognition is very difficult to perform at a distance larger than a few meters and if the person to be identified is not cooperating by holding the head still and looking into the camera.

		Such iris profile is also a stromal topographical limit separating the pars ciliaris iridis (external, towards the limbus) from pars pupillaris iridis (internal, towards the pupillary border).
		While most of the iris surface is roughly in the same plane, because the spherical segment quality of the iris and the presence of structural "accidents", the distance from an iris ridge peak to the depth of a stromal crypt is often more than 1 mm.
		Since the iris stroma is in continuous movement of several orders of magnitude (Hippus, miosis-mydriasis, imbibition with aqueous humor) the iris profile paradigm refers to the iris stromal elements in terms of real time, continuously changing, three-dimensional detail.

		Based on this unique position of the iris, iridologists maintain that it is also linked to the rest of the body through the sympathetic nervous system, and that the general conditions of the body, its organs and systems and their performance are reflected in the changing patterns of the iris.
		A complete iris analysis shows whether a person exhibits a generally good constitution or a poor one, depending upon the density of the iris fibers, the patterns, structures, colors and degrees of lightness and darkness in the iris it tells if an area of the body is inherently strong or weak.
		Iridologists point out that the iris itself is one of the most complex organs in the human body that can show a view of an ultra fine membrane of connective tissue that shows signs of degenerative diseases well before their presence is manifested in larger organs.

		The quality of the iris stroma is assessed by observing the thickness and the anatomy of the stromal cords.
		Iris traction is minimized by tying the suture with the sliding knot technique, which was introduced by Steven Seipser, MD. This technique allows the knot to slide into the anterior chamber without pulling iris tissue to the wound margin and without cumbersome intracameral knot tying maneuvers.
		Posterior synechotomy liberated the iris from the underlying capsule and several sutures were placed to imbricate the atonic iris margin until a more physiologic, smaller pupillary aperture was achieved (Slide 6).

		The ciliary epithelia and iris are often associated together as a single body, often referred to as the vascular uveal coat (which also includes the choroid) of the eye (3) or as the iris-ciliary body (4).
		The iris, which is made up of two bands of muscles, controls the pupil: the dilator, who contracts to enlarge the pupil, and the sphincter, who contracts to reduce the size of the pupil.
		The iris is made of five basic sections: the anterior border layer, the iris stromal layer, the sphincter, the dilator, and the posterior pigment epithelium (8)(7).

		The iris is made of five basic sections: the anterior border layer, the iris stromal layer, the sphincter, the dilator, and the posterior pigment epithelium (1)(5).
		The final layer of the iris is the posterior iris epithelium, a heavily pigmented layer, containing the pigment melanin (3).
		The color of the iris, a readily identifiable trait, is the result of a process known as the “scattering-selective absorption combination” (6).

	Intraocular (Eye) Melanoma Treatment - National Cancer Institute
		The comparatively low incidence of this tumor in the iris has been attributed to the characteristic features of iris melanomas, i.e., they tend to be small, slow growing, and relatively dormant in comparison with their posterior counterparts.
		Iris melanomas rarely metastasize.[4] Melanomas of the posterior uveal tract are cytologically more malignant, detected later, and metastasize more frequently than iris melanomas.
		Iris melanomas are predominantly of the spindle cell type and are usually smaller in size than posterior melanomas because of earlier detection.

		Moreover, Pax-6 mutations are associated with human anterior segment diseases such as aniridia (absence of the iris) and Peters' Anomaly (faulty developmental separation of the iris and cornea).
		Patients with a past history of HSV stromal keratitis or iritis were found to be significantly more likely to develop it again after an episode of dendritic keratitis, and thus should be followed closely.
		In contrast, stromal disease occurs as the result of recurrent infection and involves an immunopathologic process that often leads to scarring, ingrowth of blood vessels, endothelial dysfunction, and vision loss.
