| macular oedema, cystoid | Macular degeneration characterised by oedema and cystic spaces which may lead to a macular depression or hole. (12 Dec 1998) |
|---|---|
| cystoid macular oedema | Oedema of the posterior pole of the eye secondary to abnormal permeability of capillaries of the central sensory retina. (05 Mar 2000) |
| edema | <clinical sign> The presence of abnormally large amounts of fluid in the intercellular tissue spaces of the body, usually applied to demonstrable accumulation of excessive fluid in the subcutaneous tissues. Oedema may be localised, due to venous or lymphatic obstruction or to increased vascular permeability or it may be systemic due to heart failure or renal disease. Collections of oedema fluid are designated according to the site, for example ascites (peritoneal cavity), hydrothorax (pleural cavity) and hydropericardium (pericardial sac). Massive generalised oedema is called anasarca. Origin: Gr. Oide ma = swelling (18 Nov 1997) |
| edema, cardiac | A manifestation of congestive heart failure caused by increased venous and capillary pressures and often associated with the retention of sodium by the kidneys. (12 Dec 1998) |
| cystoid | 1. Bladder-like, resembling a cyst. Synonym: cystiform, cystomorphous. 2. A tumour resembling a cyst, with fluid, granular, or pulpy contents, but without a capsule. Origin: cysto-+ G. Eidos, appearance (05 Mar 2000) |
| cystoid maculopathy | Cystic degeneration of the central retina that may occur after cataract extraction, in senile macular degeneration, and in other retinal abnormalities. (05 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) |
