Abstract

Purpose : To evaluate the reliability of Pentacam® in the measurement of central corneal thickness. Cases and Method : This prospective study was made on 116 eyes of 116 patients with primary open-angle glaucoma. The age ranged from 35 to 82 years, average 61 years. Thickness of central cornea was measured by Pentacam®, ultrasonography and noncontact specular microscopy. Results : Central corneal thickness averaged 534.3±35.6μm by Pentacam®, 526.5±33.9μm by ultrasonography, and 512.7± 38.7 μm by specular microscopy. These three values were significantly correlated. No significant difference was present between values by Pentacam® and ultrasonography (p=0.30). Values by Pentacam® and specular microscopy were significantly different (p<0.00l). Conclusion : Pentacam® shows same values for central corneal thickness as ultrasonography in eyes with open-angle glaucoma.
