| barrel distortion | <microscopy> A distortion, or aberration. (05 Aug 1998) |
|---|---|
| geometrical distortion | <microscopy> A lens aberration in which the image is distorted relative to the object. See: aberration, barrel distortion, distortion, pincushion distortion. (05 Aug 1998) |
| perceptual distortion | Lack of correspondence between the way a stimulus is commonly perceived and the way an individual perceives it under given conditions. (12 Dec 1998) |
| pincushion distortion | <microscopy> A geometrical distortion in a video picture, or a form of optical aberration, that makes the middle of all sides of a square appear to bow inward. The distortion can amount to several percent of the picture height in some intensified camera tubes. See: Aberration, Distortion, Barrel distortion. (05 Aug 1998) |
| specimen distortion | <microscopy> A physical change in the specimen caused by desiccation or heating by the electron beam. (05 Aug 1998) |
| distortion | The state of being twisted out of a natural or normal shape or position. Origin: L. Dis = apart, torsio = a twisting (18 Nov 1997) |
| distortion aberration | The faulty formation of an image arising because the magnification of the peripheral part of an object is different from that of the central part when viewed through a lens. (05 Mar 2000) |
| amblyopia | <ophthalmology> The impairment of vision without detectable organic lesion of the eye. (18 Nov 1997) |
| amblyopia ex anopsia | The suppression of the central vision in one eye when the images from the two eyes are so different that they cannot be fused into one. This may be due to: 1) faulty image formation (sensory amblyopia); 2) a large difference in refraction between the two eyes (anisometropic amblyopia); or 3) the two eyes pointing in different directions (strabismic amblyopia). Most suppression amblyopia can be reversed if appropriately treated before age 6 years. Synonym: amblyopia ex anopsia. (05 Mar 2000) |
| anisometropic amblyopia | A suppression of central vision due to an unequal refractive error (anisometropia) of at least two diopters. This induces a sufficient difference in image size (aniseikonia) that the two images cannot be fused. In order to avoid confusion, the blurrier image is suppressed. Synonym: refractive amblyopia. (05 Mar 2000) |
| refractive amblyopia | A suppression of central vision due to an unequal refractive error (anisometropia) of at least two diopters. This induces a sufficient difference in image size (aniseikonia) that the two images cannot be fused. In order to avoid confusion, the blurrier image is suppressed. Synonym: refractive amblyopia. (05 Mar 2000) |
| sensory amblyopia | A suppression of central vision in one eye due to faulty image formation; for example, by a corneal scar, a cataract, or a droopy eyelid. Synonym: deprivation amblyopia. (05 Mar 2000) |
| hysterical amblyopia | An apparent loss of visual acuity or visual field with no substantiating physical signs; often due to a natural concern about visual loss combined with suggestibility and a fear of the worst; best treated with reassurance. (05 Mar 2000) |
| strabismic amblyopia | A suppression of central vision due to the two eyes pointing in different directions. The two scenes cannot be fused into a single image, so, to avoid confusion, one of the images is suppressed. (05 Mar 2000) |
| nocturnal amblyopia | Night blindness or difficulty in seeing at night. Symptom of vitamin A deficiency. (27 Sep 1997) |
