case_images: Examination of OPD, Placido, and internal OPD of the left and right eyes. OPD and Placido show normal uniform corneal topography. Internal OPD shows cloverleaf pattern consistent with PSC (courtesy of Hoopes Vision). OPD is defined as the difference of phase shift between two light waves that are from the same source which are emitted, but one goes through a change in medium, altering the refraction. Ophthalmologists assess OPD to assess corneal topography and internal ocular refraction. OPD, optical path difference.
