can oct pachymetry identify keratoconus suspects?

purpose: comparing the optical coherence tomography (oct) pachymetry patterns in keratoconus suspect and normal people methods: thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. their pachymetry pattern was obtained through oct visante in the minimum thickness spot, upper and lower corneal difference (i-s), lower temporal, and upper nasal thickness (it-sn), withdrawal or non-withdrawal of the minimum thickness area of cornea from 0-2 central zone using the output map. results: in all measured parameters a significant difference was observed between the two groups (p<0.0001). the keratoconus suspects had a thinner cornea and showed more changes in corneal thickness than the normal group. conclusion: it seems that an oct system of anterior segment can be utilized to assess patients prior to refractive surgery or keratoconus screening, along with equipments such as pentacam, and orbscan.    iranian journal of ophthalmology 201426(4):189-92 © 2014 by the iranian society of ophthalmology
