    2. Iris and knot configuration after Single Pass Four Throw (SFT) pupilloplasty as imaged by the spectral-domain optical coherence tomography

      Iris and knot configuration after Single Pass Four Throw (SFT) pupilloplasty as imaged by the spectral-domain optical coherence tomography
      Purpose: To analyze the morphological changes in the iris-knot complex configuration using spectral-domain optical coherence tomography (SD-OCT) following the single pass four throw (SFT) pupilloplasty. Methods: In this retrospective case series, eyes with SFT pupilloplasty were examined by SD-OCT (Optovue). Iris morphology compared to the normal iris, presence of specific patterns (single hump, double humps, peaks and valleys, tethering), prolene suture, knot complex (length and orientation), and intraocular lens (IOL ...

    5. Anterior Segment Optical Coherence Tomography for Imaging the Sub-Tenon Space

      Anterior Segment Optical Coherence Tomography for Imaging the Sub-Tenon Space
      In this study, we report the ability of anterior segment optical coherence tomography (AS OCT) in imaging the sub-Tenon space and its clinical application. High-speed AS OCT (Carl Zeiss Meditec, Dublin, Calif., USA) was used to visualize the sub-Tenon space during sub-Tenon injection. The sub-Tenon spaces, Tenon thickness, conjunctiva-Tenon thickness, injecting cannula position in relation to the sub-Tenon space and drug localization/distribution in the sub-Tenon space were analyzed. The ...

    6. Reliability and reproducibility of assessment of corneal epithelial thickness by Fourier domain optical coherence tomography

      Reliability and reproducibility of assessment of corneal epithelial thickness by Fourier domain optical coherence tomography
      Purpose: To analyze the intra-user reliability and inter-user reproducibility of assessment of corneal epithelial thickness by Fourier domain optical coherence tomography. Method: In this consecutive cross sectional case series performed at a tertiary ocular care institution 210 eyes of 210 subjects underwent anterior segment Fourier domain optical coherence tomography (FDOCT) with Cirrus HD-OCT. 'Caliper tool' was used to measure the corneal thickness. For reproducibility measures, the examination was done by ...

    7. Evaluation of bilateral minimum thickness of normal corneas based on Fourier-domain optical coherence tomography

      Evaluation of bilateral minimum thickness of normal corneas based on Fourier-domain optical coherence tomography
      Purpose: To determine the normative ranges and various aspects of the relationship between the minimum corneal thicknesses (MCT) in fellow eyes and the location of the MCT in relation to the central cornea using Fourier-domain optical coherence tomography (OCT).Setting: Tertiary care ophthalmic hospital, Chennai, India.Methods: In this cross-sectional observational trial, both eyes of consecutive healthy young subjects with a low refractive error and no clinical or topographic evidence ...

    8. Comparison of Fourier-Domain and Time-Domain Optical Coherence Tomography for Assessment of Corneal Thickness and Intersession Repeatability

      Purpose To compare Fourier-domain optical coherence tomography (FD-OCT) with time-domain OCT (TD-OCT) for agreement in corneal pachymetry in the central (2-mm) zone and paracentral (2- to 5-mm) zone, minimum corneal thickness, and instrument intersession reliability in candidates with normal cornea. Design Prospective comparative trial. Methods The study was performed at a tertiary care ophthalmic hospital. One hundred normal candidates with no ocular pathology except mild refractive error were included. FD-OCT ...

    9. In vivo analysis of wound architecture in 700 um microphakonit cataract surgery.

      PURPOSE: To analyze the clear corneal wound architecture in 700 mum cataract surgery (microphakonit) using anterior segment optical coherence tomography (AS-OCT). SETTING: Dr Agarwal's Eye Hospital and Eye Research Centre, Chennai, India. METHODS: Wound architecture was analyzed by AS-OCT 30 minutes after surgery and 1, 3, and 7 days postoperatively in 12 eyes (11 patients) that had microphakonit surgery. Five eyes had microphakonit with a 700 mum phaco tip ...
