Purpose.To study Pentacam topography evaluation of keratoconic eyes, with values in the
anterior segment and comparision of normal eyes.
The Pentacam measurement of 78 keratoconic eyes were evaluated and were
compared with emetropia, ametropia and post excimer laser eyes. The anterior and posterior
keratometry, topographic astigmatism, axis, aspherisity and central corneal thickness, corneal
and anterior chamber volume and anterior chamber depth of all cases were evaluated with
Anterior and posterior keratometric values were different in keratoconus eyes (p <
0.001). Anterior and posterior topographic astigmatism were same with mix astigmatic group (p=1.0 ve p=0.706). However anterior
aspheristy were similar with hyperopic excimer laser group (p=1.0), posterior aspherisity were different with all groups (p < 0.001).
Central corneal thickness were similar with myopic excimer laser group (p=1.0). There were less differences in anterior chamber
volume and anterior chamber depth values between groups.
When considering all groups together, anterior and posterior keratometry and posterior aspherisity parameters
showed statistical differences between groups. Study shows importance of posterior keratometry and posterior aspherisity beside
anterior keratometry in topographic evaluation of keratoconus.
