Disorders of sclera and cornea

Fuchs' dystrophy (pronounced fooks-DIS-trə-fe), also known as Fuchs' corneal endothelial dystrophy or FCED, is a slowly progressing corneal dystrophy that usually affects both eyes and is slightly more common in women than in men.

Arcus senilis (or arcus senilis corneae) is a white, grey, or blue opaque ring in the corneal margin (peripheral corneal opacity), or white ring in front of the periphery of the iris.

Schnyder crystalline corneal dystrophy (SCD) is a rare form of corneal dystrophy.

Band keratopathy is a corneal disease derived from the appearance of calcium on the central cornea.

Keratoconus (KC, KCN, KTCN) is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual curve.

Corneal neovascularization is the excessive ingrowth of blood vessels from the limbal vascular plexus into the cornea, caused by deprivation of oxygen from the air.

Scleritis is a serious inflammatory disease that affects the white outer coating of the eye, known as the sclera.

Thygeson's superficial punctate keratopathy (TSPK; also Thygeson Superficial Punctate Keratitis) is a disease of the eyes.

Keratitis is a condition in which the eye's cornea, the front part of the eye, becomes inflamed.

Corneal ulcer, or ulcerative keratitis, is an inflammatory or more seriously, infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma.

Kayser–Fleischer rings (KF rings) are dark rings that appear to encircle the iris of the eye.

Acanthamoeba keratitis is a rare disease in which amoebae invade the cornea of the eye.

Keratoconjunctivitis is inflammation ("-itis") of the cornea and conjunctiva.

A fungal keratitis is an 'inflammation of the eye's cornea' (called keratitis) that results from infection by a fungal organism.

Macular corneal dystrophy, also known as Fehr corneal dystrophy named for German ophthalmologist Oskar Fehr (1871-1959), is a rare pathological condition affecting the stroma of cornea.

Lattice corneal dystrophy type, also known as Biber-Haab-Dimmer dystrophy, is a rare form of corneal dystrophy.

Lisch epithelial corneal dystrophy (LECD), also known as band-shaped and whorled microcystic dystrophy of the corneal epithelium, is a rare form of corneal dystrophy first described in 1992 by Lisch et al.

Pellucid marginal degeneration (PMD), is a degenerative corneal condition, often confused with keratoconus.

Posterior amorphous corneal dystrophy (PACD) is a rare form of corneal dystrophy.

Reis-Bücklers corneal dystrophy, also known as Corneal dystrophy of Bowman layer, type I, is a rare, idiopathic corneal dystrophy in which the Bowman's layer of the cornea undergoes disintegration.

Subepithelial mucinous corneal dystrophy (SMCD) is a rare form of corneal dystrophy.

X-linked endothelial corneal dystrophy (XECD) is a rare form of corneal dystrophy described first in 2006, based on a 4-generation family of 60 members with 9 affected males and 35 trait carriers, which led to mapping the XECD locus to Xq25.

Dry eye syndrome (DES), also known as keratoconjunctivitis sicca (KCS), is the condition of having dry eyes.

Corneal abrasion is a medical condition involving the loss of the surface epithelial layer of the eye's cornea.

Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense sunlight) or artificial (e.g. the electric arc during welding) sources.

Terrien marginal degeneration is a noninflammatory, unilateral or asymmetrically bilateral, slowly progressive thinning of the peripheral corneal stroma.

Episcleritis is a benign, self-limiting inflammatory disease affecting part of the eye called the episclera.

Recurrent corneal erosion is a disorder of the eyes characterized by the failure of the cornea's outermost layer of epithelial cells to attach to the underlying basement membrane (Bowman's layer).

Thiel–Behnke dystrophy, or Corneal dystrophy of Bowman layer, type II, is a rare form of corneal dystrophy affecting the layer that supports corneal epithelium.
