|---|---|
| eclamptic retinopathy | Sudden angiospasm of retinal arterioles, later followed by retinal vascular signs of advanced hypertensive retinopathy; vascular changes disappear rapidly after termination of the pregnancy. Synonym: eclamptic retinopathy, gravidic retinopathy. (05 Mar 2000) |
| electric retinopathy | A macular burn from excessive exposure to sunlight or other intense light (e.g., the flash of a short circuit); characterised subjectively by reduced visual acuity. See: solar maculopathy. Synonym: electric retinopathy, solar retinopathy. Origin: photo-+ retina, + G. Pathos, suffering (05 Mar 2000) |
| toxaemic retinopathy of pregnancy | Sudden angiospasm of retinal arterioles, later followed by retinal vascular signs of advanced hypertensive retinopathy; vascular changes disappear rapidly after termination of the pregnancy. Synonym: eclamptic retinopathy, gravidic retinopathy. (05 Mar 2000) |
| toxic retinopathy | Retinal changes due to prolonged administration of various drugs. (05 Mar 2000) |
| transient retinopathy | Transient traumatic retinal angiopathy due to a sudden rise in venous pressure, as in compression of the body from seat belt injury; ocular fundi show large white patches associated with the retinal veins about the disk or macula, haemorrhages, and retinal oedema; thought to be due to fat embolism from bone marrow. Synonym: Purtscher's disease, transient retinopathy, traumatic retinopathy. (05 Mar 2000) |

| external exudative retinopathy | See: exudative retinitis. (05 Mar 2000) |
| Leber's idiopathic stellate retinopathy | An inflammation affecting the optic nerve head and the posterior pole of the retina, with cells in the nearby vitreous, usually producing a macular star. Synonym: papilloretinitis. (05 Mar 2000) |
| leukaemic retinopathy | Appearance of the retina in all types of leukaemia, characterised by engorgement and tortuosity of veins, scattered haemorrhages, and oedema of the retina and disk. (05 Mar 2000) |
| lipaemic retinopathy | A milkiness of the retinal vessels (lipaemia retinalis) combined with hard-edged fatty exudates, seen in patients with diabetic acidosis and hyperlipaemia. (05 Mar 2000) |
| mastectomy, simple | Removal of only the breast tissue and nipple and a small portion of the overlying skin. (12 Dec 1998) |
| microscope, simple | <microscopy> A microscope that has a single converging lens (or a combination of lenses that function optically as a single converging lens). Anton van leeuwenhoek (1632-1723) made good use of the simple microscope to look at the life within a drop of water, and such. The magnifying properties of lenses had been well known in ancient times (for example to the greeks and romans) but it was not until about 1600 that it became possible to make small lenses with the precision needed to make a microscope.
