corneal topography

A map of the variations in the curvature (and power) of the anterior surface of the cornea. The typical map shows that the average adult cornea is steeper in the vertical than in the horizontal meridian and has the form of a flattening ellipsoid. It is typically done with a photo-keratoscope or a videokeratoscope. Cornealtopography can also be determined with a scanning-slit topographer, in which a computerized system integrates a series of slit-beam images to produce a map of the curvature and elevation of the anterior and posterior surfaces enabling a diagnosis of anterior and posterior keratoconus, and indirectly providing a measurement of corneal thickness. See keratoscope; photokeratoscopy; videokeratoscope.
