| corneal layer of epidermis | The outer layer of the epidermis, consisting of several layers of flat keratinised non-nucleated cells. Synonym: corneal layer of epidermis, horny layer of epidermis. (05 Mar 2000) |
|---|
| granular layer of epidermis | A layer of somewhat flattened cells containing basophilic granules of keratohyalin and lying just above the stratum spinosum and deeply to the stratum corneum. Synonym: stratum granulosum epidermidis. (05 Mar 2000) |
|---|---|
| clear layer of epidermis | A layer of lightly staining corneocytes in the deepest level of the stratum corneum; found primarily in the thick epidermis of the palmar and plantar skin. Synonym: clear layer of epidermis. (05 Mar 2000) |
| horny layer of epidermis | The outer layer of the epidermis, consisting of several layers of flat keratinised non-nucleated cells. Synonym: corneal layer of epidermis, horny layer of epidermis. (05 Mar 2000) |
| plant epidermis | A thin layer of cells forming the outer integument of seed plants and ferns. (12 Dec 1998) |
| epidermis | 1. <dermatology> The basal layer of the mammalian epidermis contains cells that undergo repeated divisions. The cells outwards from a particular basal cell are often derived from this cell or a nearby one so that columns of cells exist running outwards from the stem cell in the basal layer from which they were derived. Such columns of cells are referred to as proliferative units. 2. <biology> Outer epithelial layer of a plant or animal. May be a single layer that produces an extracellular material (as for example the cuticle of arthropods) or a complex stratified squamous epithelium, as in the case of many vertebrate species.

| marginal corneal degeneration | Bilateral opacification and vascularization of the periphery of the cornea, progressing to formation of a gutter and ectasia. Synonym: ectatic marginal degeneration of cornea. (05 Mar 2000) |
| recurrent corneal erosion | Repeated vesiculation followed by exfoliation of the corneal epithelium. (05 Mar 2000) |
| Groenouw's corneal dystrophy | A granular type of corneal dystrophy, with autosomal dominant inheritance, a macular type of corneal dystrophy, with autosomal recessive inheritance. (05 Mar 2000) |
| ring-like corneal dystrophy | Thread-like opacities of the anterior corneal stroma, with acute, painful onset followed by decreased vision; autosomal dominant inheritance. (05 Mar 2000) |
| corneal | The cornea is an outwardly convex transparent membrane forming part of the anterior (front) portion of the eye. It is situated directly in front of the pupil an merges back to the sclera (white of the eye) and the outer margin of the iris. (27 Sep 1997) |
| corneal astigmatism | Astigmatism due to a defect in the curvature of the corneal surface. (05 Mar 2000) |
| corneal corpuscles | Connective tissue cells found between the laminae of fibrous tissue in the cornea. Synonym: Toynbee's corpuscles, Virchow's cells, Virchow's corpuscles. (05 Mar 2000) |
| corneal diseases | Diseases of the cornea. (12 Dec 1998) |
| corneal dystrophies, hereditary | Bilateral hereditary disorders of the cornea, usually autosomal dominant, which may be present at birth but more frequently develop during adolescence and progress slowly throughout life. Central macular dystrophy is transmitted as an autosomal recessive defect. (12 Dec 1998) |
| corneal dystrophy | Central corneal opacification, usually bilateral, symmetrical, and often autosomal recessive, involving predominantly epithelial, stromal, or endothelial layers, often in a typical pattern. (05 Mar 2000) |
