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. © 2014 by the iranian society of ophthalmology.
