| dark reaction | <biochemistry, plant biology> The reactions in photosynthesis that occur after NADPH and ATP production and that take place in the stroma of the chloroplast. By means of the reaction, carbon dioxide is incorporated into carbohydrate. (18 Nov 1997) |
| dark t2 lesion | <radiology> (short T2), acute haemorrhage (deoxyHb), haemosiderin, physiologic iron (basal ganglia, etc.), mucinous lesions (?) most abnormalities have long T1 and T2 (dark/bright). Compare: bright T1 lesion. (07 Mar 2000) |
| age-related macular degeneration | A common macular degeneration beginning with drusen of the macula and pigment disruption and sometimes leading to severe loss of central vision. (05 Mar 2000) |
| macular | Maculate 1. Relating to or marked by macules. 2. Denoting the central retina, especially the macula retinae. (05 Mar 2000) |
| macular amyloidosis | A localised form of amyloidosis cutis characterised by pruritic symmetrical brown reticulated macules, especially on the upper back; microscopically, amyloid is deposited as small subepidermal globules. (05 Mar 2000) |
| macular area | An oval area of the sensory retina, 3 by 5 mm, temporal to the optic disk corresponding to the posterior pole of the eye; at its centre is the central fovea, which contains only retinal cones. Synonym: area centralis, macula lutea, macular area, punctum luteum, Soemmerring's spot, yellow spot. (05 Mar 2000) |
| macular arteries | See: inferior macular arteriole, superior macular arteriole. (05 Mar 2000) |
| macular atrophy | Atrophoderma in which the skin becomes bag like and wrinkled. Synonym: atrophia maculosa varioliformis cutis, atrophoderma maculatum, macular atrophy, primary idiopathic macular atrophy, primary macular atrophy of skin. Origin: G. Anetos, relaxed, + derma, skin (05 Mar 2000) |
| macular coloboma | A defect of the central retina as a result of arrested development or intrauterine retinal inflammation. (05 Mar 2000) |
| macular degeneration | <ophthalmology> Breakdown or damage to a portion of the retina known as the macula. Symptoms include blurring of vision (in central visual field), colours appear dim and difficulty reading or performing work up close. (27 Sep 1997) |
| macular drusen | 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) |
| macular dystrophy | A group of disorders involving predominately the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the retina, retinal pigment epithelium, Bruch's membrane, choroid, or a combination of these tissues. See: Stargardt's disease, Best's disease. (05 Mar 2000) |
| macular erythema | <paediatrics> Also called baby measles. This is a nonserious but common childhood viral infection that starts with a high fever and swollen lymph glands. After 24 hours, the fever breaks and the child develops a red rash on the neck and trunk. (27 Sep 1997) |
| macular evasion | Simultaneous projection into consciousness of retinal images so different that fusion is impossible. Synonym: macular evasion. Origin: L., dread of intermingling (05 Mar 2000) |
