| mongolian macula | <dermatology> A benign bluish or bruised-appearing birthmark that is usually located on the lower back or buttocks. More common in dark-skinned races and may persist for months to years. (27 Sep 1997) |
| 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.

| neuroepithelium of macula | The specialised sensory hair cells of the epithelium of the macula sacculi and macula utriculi. Synonym: neuroepithelium maculae. (05 Mar 2000) |
| substantia propria of cornea | Proper substance of cornea, modified transparent connective tissue, between the layers of which are open spaces or lacunae nearly filled with the corneal cells or corpuscles. Synonym: substantia propria corneae. (05 Mar 2000) |
| drusen of the macula | Excrescences of Bruch's membrane that produce a window in the retinal pigment epithelium and are a feature of age-related macular retinal degeneration. Synonym: macular drusen. (05 Mar 2000) |
