Optical coherence tomography for quantitative surface topography.
We address the measurement and correction of fan distortion in optical coherence tomography (OCT). This effect arises from the scanning system configuration and prevents one, in general, from obtaining quantitative topographic data from OCT. Computer simulations allowed us to quantify the effect and evaluate its dependence on the scanning mirror separation and design of the collimating lens, as...
متن کاملSenile scleral plaques imaged with enhanced depth optical coherence tomography.
PURPOSE Senile scleral plaques (SSP) are sharply demarcated greyish areas located just anterior to the insertions of the horizontal rectus muscles and thus are frequently encountered during transscleral intravitreal injections. The aim of this study was to characterize SSP using enhanced depth imaging spectral domain anterior segment optical coherence tomography (OCT) in a cohort of patients at...
متن کاملCaveats to obtaining retinal topography with optical coherence tomography.
We read with great interest the article by Oh et al. on the assessment of retinal topography in myopic eyes using spectral domain optical coherence tomography (SD-OCT). In their article, the investigators described different characteristics of retinal topography to indicate variations in ocular shape in myopia (such as a retina sloped nasally versus temporally). Like similar prior studies using...
متن کاملCorneal topography from spectral optical coherence tomography (sOCT)
We present a method to obtain accurate corneal topography from a spectral optical coherence tomography (sOCT) system. The method includes calibration of the device, compensation of the fan (or field) distortion introduced by the scanning architecture, and image processing analysis for volumetric data extraction, segmentation and fitting. We present examples of three-dimensional (3-D) surface to...
متن کاملEvaluation of scleral-fixated intraocular lens position anomalies by anterior segment optical coherence tomography.
BACKGROUND/AIM To measure the positions of scleral-fixated intraocular lenses (IOLs) using anterior segment optical coherence tomography (OCT) and to evaluate the influence of the position of scleral-fixated IOL on the quality of vision. MATERIALS AND METHODS Twenty-six eyes of 26 patients were included in the study. The average age was 57.5 (11 to 78) years. Anterior segment images were take...
