Evaluation of corneal thickness and topography in normal eyes using the Orbscan corneal topography system.
AIMS To map the thickness, elevation (anterior and posterior corneal surface), and axial curvature of the cornea in normal eyes with the Orbscan corneal topography system. METHODS 94 eyes of 51 normal subjects were investigated using the Orbscan corneal topography system. The anterior and posterior corneal elevation maps were classified into regular ridge, irregular ridge, incomplete ridge, i...
متن کاملComparison of Central Corneal Thickness Measured through Pentacam, OCTCasia2, and Orbscan IIz in Normal Individuals
Purpose: To compare the central corneal thickness measured through Pentacam, OCTCasia2, and Orbscan IIz in normal individuals. Methods: In this cross sectional comparative study, the researcher investigated the eyes of 70 normal candidates (140 eyes) with the mean age of 31.42 ± 7.70, referring to Dr. Sedaghat eye clinic for refractive surgery. For each person, Central Corneal Thickness (CCT) w...
متن کاملMeasurement of Central Corneal Thickness Using Ultrasound Pachymetry and Orbscan II in Normal Eyes
PURPOSE To compare ultrasound pachymetry and Orbscan II for measurement of central corneal thickness (CCT) in normal eyes. METHODS The current study was performed at Labbafinejad Medical Center (LMC), Tehran, Iran. Three hundred eyes from 150 healthy individuals referred for keratorefractive surgery were assessed first by Orbscan II and then by ultrasound pachymetry, and CCT values were recor...
متن کاملKeratoconus detection using corneal topography.
UNLABELLED PURPOSETo review the topographic patterns associated with keratoconus suspects and provide criteria for keratoconus screening. METHODS Case study using maps from the NIDEK OPD-Scan II and OPD Station to highlight patterns seen in keratoconic corneas. RESULTS Five criteria are listed for the detection of keratoconus: 1) apex of the cone is not centered at the 6-o'clock semi-meridi...
متن کاملCorneal Topography Analysis of Stromal Corneal Dystrophies
OBJECTIVE The aim was to compare the corneal topography and tomography parameters of macular corneal dystrophy (MCD), granular corneal dystrophy (GCD) and lattice corneal dystrophy (LCD) patients obtained by Scheimpflug imaging system. METHODS The charts, photographs and topography images of patients were reviewed retrospectively. This study included 73 eyes of 73 patients (28 MCD, 20 GCG and...
