| anterior epithelium of cornea | The stratified squamous epithelium covering the outer surface of the cornea; it is smooth, consists usually of five layers of cells, and contains numerous free nerve endings. Synonym: epithelium anterius corneae. (05 Mar 2000) |
|---|---|
| anterior limiting layer of cornea | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| anterior surface of cornea | The external surface of the cornea. Synonym: facies anterior corneae. (05 Mar 2000) |
| marginal ring ulcer of cornea | A slowly advancing intermittent ulcer involving the circumference of the corneal margin. (05 Mar 2000) |
| vertex of cornea | The central part of the cornea, slightly thinner than the peripheral part. Synonym: vertex corneae. (05 Mar 2000) |
| reticular dystrophy of cornea | <ophthalmology> Bilateral, progressive, superficial degeneration of the corneal epithelium and adjacent Bowman's membrane. (05 Mar 2000) |
| meridian of cornea | Any line bisecting the cornea through its apex. (05 Mar 2000) |
| ring ulcer of cornea | Inflammation of the greater part or the whole of the corneal periphery. (05 Mar 2000) |
| gutter dystrophy of cornea | A marginal furrow usually inferiorly about 1 mm from the limbus; and sometimes bilateral. Synonym: keratoleptynsis. (05 Mar 2000) |
| conical cornea | Cone-shaped cornea with the apex of the cone being forward. Also called conical cornea. (12 Dec 1998) |
| cornea | <anatomy, ophthalmology> The transparent structure forming the anterior part of the fibrous tunic of the eye. It consists of five layers: 1. The anterior corneal epithelium, continuous with that of the conjunctiva. 2. The anterior limiting layer (Bowman's membrane). 3. The substantia propria or stroma. 4. The posterior limiting layer (Descemet's membrane). 5. The endothelium of the anterior chamber. Synonym: keratoderma. Origin: L. Corneus = horny (18 Nov 1997) |
| cornea farinata | Bilateral speckling of the posterior part of the corneal stroma. Synonym: floury cornea. (05 Mar 2000) |
| cornea urica | Bilateral deposition of crystalline deposits of urea and sodium urate within corneal stroma. (05 Mar 2000) |
| cornea verticillata | Congenital whorl-like opacities in the cornea. Synonym: Fleischer's vortex. (05 Mar 2000) |
| posterior limiting layer of cornea | A transparent homogeneous acellular layer between the substantia propria and the endothelial layer of the cornea; considered to be a highly developed basement membrane. Synonym: lamina limitans posterior corneae, membrana vitrea, Descemet's membrane, Duddell's membrane, entocornea, hyaloid membrane, lamina elastica posterior, limiting layers of cornea, membrana hyaloidea, posterior elastic layer, tunica vitrea, vitreous membrane.
