Unilateral Keratokonuslarda İnsidans ve Tomografik Değerlendirme

Pur po se: To evaluate the parameters of unilateral keratoconus on the basis of Scheimpflug tomography and to compare them with normal\udcontrols.\udMa te ri al and Met hod: From all patients diagnosed with keratoconus between January 2011 and January 2012, those who had topographic\udsigns of keratoconus in one eye were retrospectively evaluated. Unilateral keratoconus eyes were compared with the normal fellow eyes and\udcontrol eyes. Anterior and posterior keratometry, topographic astigmatism, axis, asphericity and central corneal thickness, corneal and anterior\udchamber volume and depth in all cases were evaluated with Pentacam. ANOVA test was used for statistical analysis.\udRe sults: 22 (14.9%) of 147 patients with keratoconus had no topographic evidence of keratoconus in the fellow eye. Statistically significant\uddifferences were noted between keratoconic eyes and fellow eyes, and between keratoconic eyes and control eyes in anterior keratometric values,\udposterior steep and mean keratometry, anterior and posterior astigmatism, anterior and posterior asphericity and central corneal thickness\ud(p=0.05). Posterior flat keratometry and anterior chamber depth were different between keratoconus and control eyes (p=0.004, p=0.006) but\udsimilar between keratoconus and fellow normal eyes (p=0.069, p=1.0).\udDis cus si on: The Scheimpflug parameters were similar between fellow eyes and control eyes.
