| simple diplopia | Double image's produced by stimuli arising from points proximal to the horopter. Synonym: homonymous diplopia, simple diplopia, uncrossed diplopia. (05 Mar 2000) |

| monocular diplopia | A double image or an extra ghost image produced in one eye, almost always by an aberration of the ocular media; for example, a corneal or lenticular irregularity, an uncorrected astigmatism or an irregularity of the vitreous or the retina. If a similar process occurs in both eyes (bilateral monocular diplopia), that is, the doubling is still present with either eye covered, the patient may still only see two images; seeing multiple images (polyopia) is rare.

| homonymous diplopia | Double image's produced by stimuli arising from points proximal to the horopter. Synonym: homonymous diplopia, simple diplopia, uncrossed diplopia. (05 Mar 2000) |
| diplopia | <ophthalmology, symptom> The perception of two images of a single object. Synonym: ambiopia, double vision, binocular polyopia. (18 Nov 1997) |
| uncrossed diplopia | Double image's produced by stimuli arising from points proximal to the horopter. Synonym: homonymous diplopia, simple diplopia, uncrossed diplopia. (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.

| simple absence | A brief clouding of consciousness accompanied by the abrupt onset of 3/sec spikes and waves on EEG. Synonym: pure absence. (05 Mar 2000) |
| simple anchorage | Anchorage in which the resistance to the movement of one or more teeth comes solely from resistance to tipping movement of the anchorage unit. (05 Mar 2000) |
