| topography, medical | The systematic surveying, mapping, charting, and description of specific geographical sites, with reference to the physical features that were presumed to influence health and disease. Often associated with hippocrates, the process became a significant part of public health investigation and epidemiological methodology, particularly between the 17th and 19th centuries. Medical topography should be differentiated from epidemiology in that the former emphasizes geography whereas the latter emphasizes disease outbreaks. (dr. James h. Cassedy, nlm history of medicine division) (12 Dec 1998) |
| moire topography | A method of three-dimensional morphometry in which contour maps are produced from the overlapping interference fringes created when an object is illuminated by beams of coherent light issuing from two different point sources. (12 Dec 1998) |

| corneal topography | Measurement of the anterior surface of the cornea, its curvature and shape. It is used often to diagnose keratoconus and other corneal diseases, and corneal changes after keratotomy and keratoplasty. A significant application is in the fitting of contact lenses. In performing corneal topography, many different techniques can be employed: keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing, etc. (12 Dec 1998) |
