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.
