Screening of forme fruste keratoconus with the ocular response analyzer.
PURPOSE To evaluate the performance of the Ocular Response Analyzer (ORA) in the screening of forme fruste keratoconus (FFKc). METHODS A retrospective comparative study was conducted involving 180 eyes. ORA preoperative data were analyzed for 125 normal control eyes (64 patients) undergoing laser in situ keratomileusis (LASIK) without corneal ectasia after 24 months of follow-up and 55 case e...
متن کاملComparative Evaluation of Elevation, Keratometric, Pachymetric and Wavefront Parameters in Normal Eyes, Subclinical Keratoconus and Keratoconus with a Dual Scheimpflug Analyzer
Purpose: To compare the corneal parameters in normal corneas, forme fruste keratoconus (FFKC) and keratoconus measured with a dual Scheimpflug analyzer. Materials and methods: A total of 372 eyes of 197 patients were prospectively enrolled in the study and divided into three groups: 148 eyes of 102 patients with keratoconus, 47 contralateral topographically normal eyes of clinically evident ker...
متن کاملComparison of and correlation between anterior and posterior corneal elevation maps in normal eyes and keratoconus-suspect eyes.
PURPOSE To compare the anterior and posterior corneal elevation maps between keratoconus-suspect eyes and normal eyes. SETTING Rothschild Foundation, AP-HP, University Paris VII, Hôpital Bichat Claude Bernard, Paris, France. METHODS The anterior and posterior corneal surface elevations were analyzed and compared in 60 normal myopic patients and 48 keratoconus-suspect patients. The anterior ...
متن کاملBiomechanical parameters of the cornea measured with the Ocular Response Analyzer in normal eyes
BACKGROUND To evaluate the relationships between Reichert Ocular Response Analyzer (ORA) parameters corneal hysteresis (CH) and corneal response factor (CRF) and ocular dimensions, age and intraocular pressure. METHODS Two hundred and twelve eyes of 212 participants with no ocular pathology had CH and CRF measured with the ORA. Intraocular pressure (IOP) was measured with the Dynamic Contour ...
متن کاملComparative Analysis of Anterior Segment Parameters in Normal and Keratoconus Eyes Generated by Scheimpflug Tomography
Purpose. To assess and compare the anterior and posterior corneal surface parameters, keratoconus indices, thickness profile data, and data from enhanced elevation maps of keratoconic and normal corneas with the Pentacam Scheimpflug corneal tomography and to determine the sensitivity and specificity of these parameters in discriminating keratoconus from normal eyes. Methods. The study included ...
