Abstract Details

Purpose:

To evaluate the keratometric and pachymetric parameters of healthy eyes with steep cornea and keratoconus (KC) affected ones with Scheimpflug camera.

Setting:

Briz-L Eye Clinic, Baku, Azerbaijan

Methods:

In this study, 49 KC (Amsler-Krumeich stage 1) eyes and 36 healthy ones were enrolled. A complete ophthalmic evaluation and a Scheimpflug camera scan, were performed in every eye included in the study. Tomographic parameters, as well as pachymetric progression indices (PPI), Ambrosio relational thickness (ART), index of surface variance (ISV), index of vertical asymmetry (IVA), center keratoconus index (CKI), index of height asymmetry (IHA) and index of height decentration (IHD), radius minimum (RM) were collected and statistically compared between two groups.

Results:

PPI and ART parameter values were significantly different (p<0.05) between KC and healthy eyes. There were no significant difference in K mean, Kmax, anterior chamber angle, Rmin, back and front astigmatism, and Q values from the frontal corneal parameters between stage 1 keratoconic and normal Caucasian eyes with steep cornea. All remained parameters showed significant difference between groups (p<0.05 for all).

Conclusions:

Scheimpflug camera is able to detect corneal morphological differences between stage 1 KC eyes and healthy ones with steep cornea in Caucasians.
