Guide to Pentacam Interpretation for Keratoconus and Corneal Ectasia

Purpose: The Pentacam, a Scheimpflug-based tomographic device, is an invaluable tool for identifying corneal diseases. The purpose of this review was to explain the data and images available on the 4 Maps Refractive , Belin/Ambrósio Enhanced Ectasia (BAD display) , and the Belin ABCD Progression Display. Methods: From the Pentacam manual, published literature, and expert knowledge, details of each report were synthesized. Results: A comprehensive explanation of the values and figures for the above listed displays. Conclusions: The Pentacam measures and provides an abundance of data for the cornea and anterior segment. Through this information, clinicians can better diagnose and identify progression of corneal ectasia and keratoconus and effectively screen refractive surgery patients.
