    2. Keratoconus Diagnosis with Optical Coherence Tomography Pachymetry Mapping

      Objective To detect abnormal corneal thinning in keratoconus using pachymetry maps measured by high-speed anterior segment optical coherence tomography (OCT). Design Cross-sectional observational study. Participants Thirty-seven keratoconic eyes from 21 subjects and 36 eyes from 18 normal subjects. Methods The OCT system operated at a 1.3 μm wavelength with a scan rate of 2000 axial scans per second. A pachymetry scan pattern (8 radials, 128 axial scans each; 10 ...

    3. Clinical and research applications of anterior segment optical coherence tomography – a review

      al coherence tomography (OCT) is being employed more and more often to image pathologies and surgical anatomy within the anterior segment, specifically in anterior chamber biometry, corneal pachymetric mapping, angle evaluation and high-resolution cross-sectional imaging. The cross-sectional imaging capability of OCT is similar to ultrasound, but its higher resolution allows OCT to measure and visualize very fine anatomic structures. No contact is required. In this review, we describe the utility ...

    4. Quantitative Optical Coherence Tomography Findings in Various Subtypes of Neovascular Age-Related Macular Degeneration

      PURPOSE. To compare the volume of various spaces visible on optical coherence tomography (OCT) images in different angiographic lesion subtypes of neovascular age-related macular degeneration (AMD). METHODS. Sixty-six cases of previously untreated, active subfoveal choroidal neovascularization (CNV) associated with AMD were retrospectively collected. CNV lesions were classified as occult with no classic CNV, minimally classic CNV, predominantly classic CNV, or CNV lesions with associated retinal angiomatous proliferation (RAP). Corresponding OCT ...

    5. Relationship Between Optical Coherence Tomography Retinal Parameters and Visual Acuity in Neovascular Age-Related Macular Degeneration

      Purpose To investigate the relationship between optical coherence tomography (OCT)-derived measurements of retinal morphology and visual acuity in patients with neovascular age-related macular degeneration (AMD). Design Retrospective cross-sectional study. Participants A total of 216 consecutive patients (216 eyes) newly diagnosed with neovascular AMD who underwent StratusOCT imaging at the time of diagnosis. Methods Best-corrected Snellen visual acuity was recorded for each patient. Raw exported StratusOCT images for each patient ...

    7. Changes in Angle Configuration After Phacoemulsification Measured by Anterior Segment Optical Coherence Tomography.

      Purpose: To measure changes in angle width after phacoemulsification and intraocular lens (IOL) implantation using anterior segment optical coherence tomography (AS-OCT). Materials and Methods: Twenty-one patients undergoing cataract surgery were recruited from the National University Hospital, Singapore. AS-OCT images were obtained of nasal and temporal angle quadrants before and at 1-month after surgery. Optical measurements of central anterior chamber depth were obtained, and gonioscopic measurement of angle width was recorded ...

    9. Imaging Serpiginous Choroidopathy With Spectral Domain Optical Coherence Tomography

      The use of spectral domain optical coherence tomography (SD-OCT) in the study of chronic serpiginous choroiditis was evaluated. Two patients with chronic serpiginous choroiditis were imaged using two prototype SD-OCT systems (6-µm axial resolution). Raster scans covering 6 × 6 × 2-mm regions of the retina were obtained, enabling the study of different retinal cross-sectional images. Thickness maps were obtained after segmentation of retinal layers, which could be compared with those on ...

    11. Macular Thickness Measurements in Normal Eyes Using Spectral Domain Optical Coherence Tomography

      BACKGROUND AND OBJECTIVE Knowledge of the macular thickness in a normal population is important for the evaluation of pathological macular change. The purpose of this study was to define and measure macular thickness in normal eyes using spectral domain optical coherence tomography (OCT). PATIENTS AND METHODS Fifty eyes from 50 normal subjects (29 men and 21 women, aged 22 to 68 years) were scanned with a prototype Cirrus HD-OCT system ...
