| unequal retinal image | A condition in which the ocular image of an object as seen by one eye differs in size and shape from that seen by the other. (12 Dec 1998) |
| 11-cis-retinal | The isomer of retinaldehyde that can combine with opsin to form rhodopsin; it is formed from 11-trans-retinal by retinal isomerase. Synonym: neoretinal b. (05 Mar 2000) |
| adiposogenital dystrophy | A disorder characterised primarily by obesity and hypogonadotrophic hypogonadism in adolescent boys; dwarfism is rare, and when present is thought to reflect hypothyroidism. Visual loss, behavioural abnormalities, and diabetes insipidus may occur. Frohlich's syndrome often is used synonymously for this disorder, although the original case involved a pituitary tumour; most cases are thought to result from hypothalamic dysfunction in areas regulating appetite and gonadal development. The most common causes are pituitary and hypothalamic neoplasms. Synonym: adiposis orchica, adiposogenital degeneration, adiposogenital dystrophy, adiposogenital syndrome, hypophysial syndrome, hypothalamic obesity with hypogonadism. Origin: L. Fr. G. Dys-, bad, + trophe, nourishment (05 Mar 2000) |
| adult pseudohypertrophic muscular dystrophy | Muscular dystrophy of late onset, often in the second or third decade, with relatively mild course; X-linked recessive inheritance; perhaps allelic with Duchenne's dystrophy, but milder and not a genetic lethal. Compare: Duchenne dystrophy. Synonym: Becker type tardive muscular dystrophy. (05 Mar 2000) |
| Barnes' dystrophy | A rare type of muscular dystrophy, in which muscles are often hypertrophic and stronger than normal, but later become weak and atrophic. (05 Mar 2000) |
| Becker's muscular dystrophy | An X-linked inherited disorder characterised by slowly progressive muscle weakness of the legs and pelvis. Other symptoms and findings include increased difficulty walking, intellectual retardation, fatigue and pseudohypertrophy of the calf muscles. (27 Sep 1997) |
| Becker type muscular dystrophy | A muscular dystrophy that has many of the clinical features of Duchenne muscular dystrophy e.g., symmetrical involvement of first the pelvicrural muscles and then the pectoral girdle and proximal upper extremity muscles; pseudohypertrophy, especially of the calf muscles but with a much later age of onset (35-45 years), and more benign course. X-linked inheritance. (05 Mar 2000) |
| Becker type tardive muscular dystrophy | Muscular dystrophy of late onset, often in the second or third decade, with relatively mild course; X-linked recessive inheritance; perhaps allelic with Duchenne's dystrophy, but milder and not a genetic lethal. Compare: Duchenne dystrophy. Synonym: Becker type tardive muscular dystrophy. (05 Mar 2000) |
| benign pseudohypertrophic muscular dystrophy | <neurology> An X-linked inherited disorder characterised by slowly progressive muscle weakness of the legs and pelvis. Other symptoms and findings include increased difficulty walking, intellectual retardation, fatigue and pseudohypertrophy of the calf muscles. (06 Aug 1998) |
| 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) |
| map-dot-fingerprint dystrophy | Fingerprint dystrophy accompanied by map-like patterns and microcystic epithelial inclusions. (05 Mar 2000) |
| reflex sympathetic dystrophy | A syndrome of pain and tenderness, usually to a hand or foot, associated with vasomotor instability, skin changes and rapid development of bony demineralisation (osteoporosis). Frequently will follow a localised trauma, stroke or peripheral nerve injury. (27 Sep 1997) |
| reflex sympathetic dystrophy syndrome | <syndrome> A condition that features a group of typical symptoms, including pain (often burning type), tenderness, and swelling of an extremity associated with varying degrees of sweating, warmth and/or coolness, flushing, discoloration, and shiny skin. (12 Dec 1998) |
| vitreo-tapetoretinal dystrophy | Autosomal recessive bilateral peripheral and central retinoschisis with pigmentary degeneration of the retina, chorioretinal atrophy, vitreous degeneration, and night blindness. Synonym: Favre's dystrophy. (05 Mar 2000) |
