| vitelliform degeneration | Degeneration in Best's disease, with the macular region of each eye occupied by a bright orange-yellow circular deposit resembling an egg yolk, followed by scarring; autosomal dominant inheritance. Synonym: vitelliruptive degeneration. (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 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) |
| Sorsby's macular degeneration | Macular degeneration that occurs during the fifth decade of life, with sudden development of a central scotoma in one eye followed rapidly by a similar lesion in the opposite eye; autosomal dominant inheritance. Synonym: Sorsby's macular degeneration. (05 Mar 2000) |
| disciform macular degeneration | Foveal or parafoveal subretinal neovascularization with retinal separation and haemorrhage leading finally to a circular mass of fibrous tissue with marked loss of visual acuity. Synonym: disciform macular degeneration. (05 Mar 2000) |
| familial pseudoinflammatory macular degeneration | Macular degeneration that occurs during the fifth decade of life, with sudden development of a central scotoma in one eye followed rapidly by a similar lesion in the opposite eye; autosomal dominant inheritance. Synonym: Sorsby's macular degeneration. (05 Mar 2000) |
| vitelliform | Relating to or resembling the yolk of an egg. (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 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) |
