Summary of "Relationship Between the Degree of Iris Pigmentation and Corneal Sensitivity to a Cooling Stimulus."

To explore the relationship between the degree of iris pigmentation and corneal sensitivity threshold (CST) on a variety of different ethnicities, using the air-jet noncontact corneal aesthesiometer and by applying a consistent method of subject iris pigmentation classification.

Corneal Substructure Dosimetry Predicts Corneal Toxicity in Patients with Uveal Melanoma Treated with Proton Beam Therapy.

The present study examines the relationship between dose to corneal substructures and incidence of corneal toxicity within six months of proton beam therapy (PBT) for uveal melanoma. We aim to develop...

Association of Retinopathy of Prematurity and Plateau iris.

Medical and Biotech [MESH] Definitions

Tumors of the iris characterized by increased pigmentation of melanocytes. Iris nevi are composed of proliferated melanocytes and are associated with neurofibromatosis and malignant melanoma of the choroid and ciliary body. Malignant melanoma of the iris often originates from preexisting nevi.

A grouping of three closely linked conditions: iris nevus (or Cogan-Reese) syndrome, Chandler Syndrome, and essential (progressive) iris atrophy. The most common features of this syndrome are the movement of endothelial cells off the cornea onto the iris leading to corneal swelling, distortion of the iris, and variable degrees of distortion of the pupil. The abnormal cell movement plugs fluid outflow channels of the eye causing GLAUCOMA.

The deposition of flaky, translucent fibrillar material most conspicuous on the anterior lens capsule and pupillary margin but also in both surfaces of the iris, the zonules, trabecular meshwork, ciliary body, corneal endothelium, and orbital blood vessels. It sometimes forms a membrane on the anterior iris surface. Exfoliation refers to the shedding of pigment by the iris. (Newell, Ophthalmology, 7th ed, p380)

Diseases affecting PIGMENTATION, including SKIN PIGMENTATION.

New blood vessels originating from the corneal veins and extending from the limbus into the adjacent CORNEAL STROMA. Neovascularization in the superficial and/or deep corneal stroma is a sequel to numerous inflammatory diseases of the ocular anterior segment, such as TRACHOMA, viral interstitial KERATITIS, microbial KERATOCONJUNCTIVITIS, and the immune response elicited by CORNEAL TRANSPLANTATION.
