Corneal Topography

History of Corneal ImagingUsesGeneral PrinciplesInterpretation of A Topography PrintoutA modern topography printout can be quite daunting for the beginner because of the volumes of data it contains. This is a major shift from the rather simplistic videokeratographs and keratometers. A stepwise approach is useful in interpretation. Step 1. Correctly identify the patient, age and eye. Step 2 . Start by looking at the quad or multi mapSee more on eyewiki nih.gov
