Abstract

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.
