Title: Intraocular Pressure, Central Corneal Thickness and Corneal Curvature in Anisomyopic Adults
Abstract: Purpose To examine if intraocular pressure (lOP), central corneal thickness (CCT) and corneal curvature (CC) are different in less myopic eyes and more myopic eyes in anisomyopic adults. Methods: A retrospective study of 63 anisomyopic Chinese adults with anisometropia not<2D in spherical equivalent refraction were studied. They were divided into two groups according to refractive status: group A being anisomyopia ≧2D but<3D and group B being anisomyopia ≧3D. lOP was measured with a noncontact tonometer (Topcon CT-80), CCT was measured with Orbscan corneal topography system (ORBTEK) and cycloplegic refraction and CC were measured with an autokerato-refractometer (Topcon KR-7100). Results: There were no statistically significant differences in lOP and CCT between the less myopic eyes and more myopic eyes in all anisomyopes. The more myopic eyes had a significantly increased mean keratometric power compared with the less myopic eyes in anisomyopes of group A (P=0.03). The keratometric power of the more myopic eyes was not different compared to the less myopic eyes in anisomyopes of group B (P=0.32). Conclusions: Refractive error difference in anisomyopic adults is not related to differences in lOP and CCT. The more myopic eyes had a significantly steeper cornea compared with the less myopic eyes in patients with anisomyopia ≧2D but<3D, but not in those with anisomyopia≧3D.
