    3. Optical coherence tomography angiography in glaucoma care

      Optical coherence tomography angiography in glaucoma care
      Rapid improvements in optical coherence tomography (OCT) technology have allowed for enhancement of both image resolution and scanning speed, and the development of vascular assessment modality. Optical coherence tomography angiography (OCTA) is the non-invasive in vivo imaging of the vasculature located within the retina and optic nerve head area. The principle of OCTA is to use the variations in OCT signals caused by moving particles as the contrast mechanism for ...

    8. Ethnic Differences in Trabecular Meshwork Height by Optical Coherence Tomography

      Ethnic Differences in Trabecular Meshwork Height by Optical Coherence Tomography
      Importance Differences in ocular anatomy may contribute to ethnic differences in glaucoma risk. Because the trabecular meshwork (TM) plays an important role in aqueous outflow, its anatomy in relation to at-risk populations may provide insight into a potential contributor to elevated intraocular pressure and thus to probability of glaucoma development. Objective To investigate whether differences exist in TM height between ethnic groups. Design, Setting, and Participants This prospective study took ...

    9. Anterior Segment Optical Coherence Tomography Parameters in Phacomorphic Angle Closure and Mature Cataracts

      Anterior Segment Optical Coherence Tomography Parameters in Phacomorphic Angle Closure and Mature Cataracts
      Purpose:To describe anterior segment optical coherence tomography (AS-OCT) parameters in phacomorphic angle closure (PMAC) eyes, mature cataract eyes and their fellow eyes, and identify those parameters that could be used to differentiate PMAC eyes from those with mature cataract and no PMAC. Methods:In this cross-sectional study a total of 33 PMAC subjects and 34 control patients with unilateral mature cataracts were enrolled. All patients underwent AS-OCT imaging and ...
