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) |
| topography | <microscopy> The surface features of an object or how it looks its texture, direct relation between these features and materials properties (hardness, reflectivity etc.). (05 Aug 1998) |
| 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) |
