    2. Changes in the deep vasculature assessed using anterior segment OCT angiography following trabecular meshwork targeted minimally invasive glaucoma surgery

      Changes in the deep vasculature assessed using anterior segment OCT angiography following trabecular meshwork targeted minimally invasive glaucoma surgery
      The effect of trabecular meshwork (TM)-targeted minimally invasive glaucoma surgery (MIGS) on the vasculature assessed using anterior segment (AS)-optical coherence tomography angiography (OCTA) has not been established. In this prospective, longitudinal study, we investigated changes in the deep vasculature following TM-targeted MIGS using AS-OCTA for open-angle glaucoma in 31 patients. AS-OCTA images of the sclera and conjunctiva at the nasal corneal limbus were acquired preoperatively and 3 months ...

    5. Combining Optical Coherence Tomography and Fundus Photography to Improve Glaucoma Screening

      Combining Optical Coherence Tomography and Fundus Photography to Improve Glaucoma Screening
      We aimed to evaluate the accuracy of glaucoma screening using fundus photography combined with optical coherence tomography and determine the agreement between ophthalmologists and ophthalmology residents. We used a comprehensive ophthalmologic examination dataset obtained from 503 cases (1006 eyes). Of the 1006 eyes, 132 had a confirmed glaucoma diagnosis. Overall, 24 doctors, comprising two groups (ophthalmologists and ophthalmology residents, 12 individuals/group), analyzed the data presented in three screening strategies ...

    6. Optical coherence tomography in coronary atherosclerosis assessment and intervention

      Optical coherence tomography in coronary atherosclerosis assessment and intervention
      Since optical coherence tomography (OCT) was first performed in humans two decades ago, this imaging modality has been widely adopted in research on coronary atherosclerosis and adopted clinically for the optimization of percutaneous coronary intervention. In the past 10 years, substantial advances have been made in the understanding of in vivo vascular biology using OCT. Identification by OCT of culprit plaque pathology could potentially lead to a major shift in ...

    8. The intercapillary space spectrum as a marker of diabetic retinopathy severity on optical coherence tomography angiography

      The intercapillary space spectrum as a marker of diabetic retinopathy severity on optical coherence tomography angiography
      Microcirculatory disturbance plays a pivotal role in the pathogenesis in diabetic retinopathy (DR). We retrospectively quantified the total counts and morphological features of intercapillary spaces, i.e., intercapillary areas and nonperfusion areas (NPAs), on swept-source optical coherence tomography angiography (SS-OCTA) images and to evaluate their associations with DR severity grades. We acquired 3 3 mm OCTA images in 75 eyes of 62 diabetic patients and 22 eyes of 22 nondiabetic ...

    9. Unilateral transient high myopization after pediatric strabismus surgery: Observation by anterior segment optical coherence tomography

      Unilateral transient high myopization after pediatric strabismus surgery: Observation by anterior segment optical coherence tomography
      Purpose: To describe an unusual case of unilateral transient high myopization after pediatric strabismus surgery. Observations: A 6-year-old girl with intermittent exotropia had undergone strabismus surgery and experienced a transient decrease in best-corrected visual acuity (BCVA, from 20/20 to 20/33) with high myopization (from +0.25 D to -9.00 D). Slit-lamp microscopy showed anterior chamber inflammation and a narrow angle only in the affected eye. Anterior segment ...

      Peripheral Chorioretinal Imaging Through a Front Prism on Optical Coherence Tomography Angiography
      Purpose: To evaluate the clinical feasibility of peripheral chorioretinal imaging through a front prism on swept-source optical coherence tomography angiography (SS-OCTA). Methods: We prospectively obtained en face OCTA images using SS-OCTA in 10 eyes of 10 healthy volunteers. For the peripheral chorioretinal imaging, the scanning laser passed and refracted through a 45-90-45 right-angle prism. We evaluated the qualitative and quantitative characteristics of chorioretinal vessels in the periphery. Results: Using peripheral ...

      Longitudinal changes in complete avascular area assessed using anterior segmental optical coherence tomography angiography in filtering trabeculectomy bleb
      Optical coherence tomography angiography (OCTA) is a new technique for non-invasive imaging of blood vessels, allowing combined evaluation of both deep and surface vessels. The purpose of this study was to evaluate the post-trabeculectomy longitudinal changes in complete avascular area (CAA) of filtering blebs using anterior segment (AS-) OCTA and their association with surgical outcomes. This study included 57 eyes of 53 patients who had undergone trabeculectomy with mitomycin C ...

    12. Improved accuracy of tissue glucose measurement using low magnification optical coherence tomography

      Improved accuracy of tissue glucose measurement using low magnification optical coherence tomography
      Optical coherence tomography (OCT) has a comparatively high spatial resolution among tomographic bioimaging techniques and is less affected by changes in physiological conditions such as temperature, blood pressure, and osmolytes in the tissue. OCT detects changes in the refractive index of tissues, which is a function of the tissue glucose concentration (TGC). OCT signal intensity generally decreases with tissue depth, and its slope is expected to show a negative correlation ...
