| keratectomy | An operation done to change the refraction of the cornea; a crescentic piece of corneal stroma is removed and the resultant corneal wound is sutured. This steepens the cornea and increases its power in that axis. Origin: kerato-+ G. Ektome, excision Photorefractive keratectomy, removal of part of the cornea with a laser to change its shape, and thus to modify the refractive error of the eye (reduce its myopia, for example). (05 Mar 2000) |
| keratectomy, photorefractive, excimer laser | A type of refractive surgery of the cornea to correct myopia and astigmatism, using an excimer laser. An excimer laser is a laser containing a noble gas, such as helium or neon, which is based on a transition between an excited state in which a metastable bond exists between two gas atoms and a rapidly dissociating ground state. The extremely precise laser light reshapes the surface of the cornea without making an incision. This procedure can reduce much higher degrees of myopia than radial keratotomy (keratotomy, radial), although it generally takes longer for vision to clear. (12 Dec 1998) |
| ichthyosis, lamellar | A chronic, congenital ichthyosis inherited as an autosomal recessive trait. Infants are usually born encased in a collodion membrane which sheds within a few weeks. Scaling is generalised and marked with grayish-brown quadrilateral scales, adherent at their centres and free at the edges. In some cases, scales are so thick that they resemble armored plate. (12 Dec 1998) |
| lamellar | 1. Arranged in thin plates or scales. Synonym: lamellate, lamellated. 2. Relating to lamellae. (05 Mar 2000) |
| lamellar bone | The normal type of adult mammalian bone, whether cancellous or compact, composed of parallel lamellae in the former and concentric lamellae in the latter; lamellar organization reflects a repeating pattern of collagen fibroarchitecture. (05 Mar 2000) |
| lamellar cataract | A cataract in which the opacity is limited to the cortex. Synonym: zonular cataract. (05 Mar 2000) |
| lamellar granule | A membrane-bound granule, 100 to 500 nm in diameter, located in the upper layers of the stratum spinosum of certain stratified squamous epithelia. Synonym: lamellar granule, membrane-coating granule, Odland body. (05 Mar 2000) |
| lamellar ichthyosis | A dry form of congenital ichthyosiform erythroderma, an autosomal recessive trait present at birth; characterised by large, coarse scales over most of the body with thickened palms and soles, and associated with ectropion; histologically, there is hyperkeratosis, a prominent granular layer in the epidermis, slight acanthosis, many mitotic figures, and normal or reduced epidermal cell turnover. See: collodion baby, harlequin foetus. (05 Mar 2000) |
| lamellar keratoplasty | Keratoplasty in which only the anterior layer of the cornea is used (not a tectonic keratoplasty). Synonym: lamellar keratoplasty, layered keratoplasty. (05 Mar 2000) |
| lamellar phase | <biochemistry> A lamellar organisation of phospholipids that are packed as a bilayer with hydrophobic acyl tails inwardly directed and polar head groups on the outside surfaces. It is this bilayer that forms the basis of membranes in cells, though in most cellular membranes a very substantial proportion of the area may be occupied by integral proteins. The triple layered appearance of membranes seen in electron microscopy is thought to arise because the osmium tetroxide binds to the polar regions leaving a central, unstained, hydrophobic region.
