  • anterior
  • A form of anterior segment dysgenesis, a group of defects affecting anterior structures of the eye including cornea, iris, lens, trabecular meshwork, and Schlemm canal. (uniprot.org)
  • Anterior segment dysgeneses result from abnormal migration or differentiation of the neural crest derived mesenchymal cells that give rise to components of the anterior chamber during eye development. (uniprot.org)
  • Different anterior segment anomalies may exist alone or in combination, including iris hypoplasia, enlarged or reduced corneal diameter, corneal vascularization and opacity, posterior embryotoxon, corectopia, polycoria, abnormal iridocorneal angle, ectopia lentis, and anterior synechiae between the iris and posterior corneal surface. (uniprot.org)
  • Clinical conditions falling within the phenotypic spectrum of anterior segment dysgeneses include aniridia, Axenfeld anomaly, Reiger anomaly/syndrome, Peters anomaly, and iridogoniodysgenesis. (uniprot.org)
  • Recent applications for imaging the anterior segment open a new era for aiding the diagnosis of vascular lesions of the anterior eye. (biomedcentral.com)
  • For example, the conjunctival vascular network can be easily visualized, and quantitative analysis of the vessel may further boost the use of OCTA for the anterior segment of the eye. (biomedcentral.com)
  • This thematic series focuses on the recent applications of OCTA for vascular imaging of the anterior segment and aims to publish review articles and original research of the latest discovery and applications in the field. (biomedcentral.com)
  • Optical coherence tomography angiography (OCTA) is a novel non-invasive angiography technology that has recently been extensively studied for its utility in anterior segment imaging. (biomedcentral.com)
  • While gonioscopy remains the gold standard by which the angle is evaluated, numerous anterior segment imaging techniques exist to assist in determining anterior segment structure. (aao.org)
  • Anterior segment OCT was first described in 2000 (Hoerauf at al, 2000). (aao.org)
  • Anterior segment OCT has the clear advantage over UBM in that it is a noncontact examination and can be performed with the patient sitting upright. (aao.org)
  • At its inception, anterior segment imaging was most frequently used to determine angle anatomy, although its uses have greatly expanded over the years ( 11‑1 to 11‑8 ). (aao.org)
  • One of the most useful aspects of anterior segment imaging is the ability to determine anterior segment configuration not always well appreciated on gonioscopic examination. (aao.org)
  • For example, in plateau iris configuration, anterior segment imaging is very effective in recognizing both the anteriorly rotated ciliary body and the narrow peripheral angle (Pavlin et al, 1992). (aao.org)
  • Anterior segment imaging is useful diagnostically in aqueous misdirection, demonstrating the anterior rotation of the ciliary body, and tight apposition of the iris and lens to the cornea (Ishikawa, 2004). (aao.org)
  • Structures such as IOL haptics, filtering blebs, and intraocular foreign bodies have all been evaluated by UBM or anterior segment OCT. Anterior segment OCT also holds particular promise in evaluating the cornea after lamellar surgery. (aao.org)
  • In this video from Glaucoma Subspecialty Day, Dr. Joel Schuman discusses the applications and advantages of ultrasound biomicroscopy and anterior segment optical coherence tomography (AS-OCT) in the detection and quantitative assessment of primary angle-closure glaucoma. (aao.org)
  • The intersegmental region (ISR) consists of the visible segment border and narrow strips of cells anterior and posterior to it. (springer.com)
  • The anterior strip (w-ISR) is white and merges with the white segment region (wS) in front of it, and the posterior strip (r-ISR) is red and merges posteriorly with the red segment region (rS). (springer.com)
  • adjacent segments
  • Intra-operative x-ray after patient positioning in the lateral decubitus position shows obvious coronal deformity at the adjacent segments (Fig. 5). (spineuniverse.com)
  • The role which the ISR plays as a barrier between adjacent segments can essentially be interpreted on the basis of differences in cell adhesiveness. (springer.com)
  • This property can explain the hitherto not understood healing capacity of the ISR which even after wounding prevents cellular interactions between adjacent segments so effectively. (springer.com)
  • The largest subdivision of a lobe of the lung, supplied by a direct branch of a lobar bronchus and separated from adjacent segments by connective tissue septa. (dictionary.com)
  • Elevation
  • His primary physician diagnosed acute myocardial infarction on the basis of ST elevation in leads V2 and V3 ( Figure 1 A). ST segments in leads I and aVL became elevated 30 minutes later, when chest pain worsened ( Figure 2 B). On arrival at our hospital, the patient had a blood pressure of 70/50 mm Hg in both arms and a heart rate of 54 bpm. (ahajournals.org)
  • decline
  • Automakers such as Hyundai, Ford, Kia and Seat are experimenting with new compact-car body styles in a bid to slow the steady sales decline in Europe's second-largest segment. (autonews.com)
  • abdominal
  • In Dysdercus the abdominal segments are isolated from each other by an intersegmental region which can be distinguished on the basis of morphological and physiological criteria. (springer.com)
  • consider
  • CAPE TOWN: Brands looking to enter African markets ought to look beyond the traditional approach and consider segmenting by attitude rather than geography a study has said. (warc.com)
  • approach
  • There are two approaches to segmenting a market - a discovery approach or an analytic approach. (wikipedia.org)
  • An analytic approach is a much more research and data based approach, where two sets of information are derived and used to segment the market. (wikipedia.org)
  • The first approach gives them an idea on the future growth of the segment, and whether its investment outcome is worthwhile. (wikipedia.org)
  • The second approach is more based around the observation of the buying behaviours of the segment and is more based around primary research. (wikipedia.org)
  • The discovery approach is more suited to a market with a limited customer base, and the process of discovering segments is based on interest in the offer or a similar offer the business may be able to provide. (wikipedia.org)
  • Because of this, a discovery-based approach is a much timelier process by which to determine the profitable segments. (wikipedia.org)
  • ability
  • This goes hand in hand with an earlier study demonstrating the ability of monocolonization with Segmented Filamentous Bacteria to dramatically increase mucosal IgA levels. (wikipedia.org)
  • share
  • We are guessing either certain segments share mass with adjoining segments, or more likely, the head is considered as part of the whole trunk in Plagenhoef's data. (exrx.net)
  • levels
  • The adhesiveness properties of the r-ISR and w-ISR can explain why the segment boundary forms such a straight line and why the ISR tends to grow between tissues from non-contiguous segment levels. (springer.com)
  • method
  • The features() method returns annotations across the length of the segment. (cpan.org)
  • Called with a TypeID, the method will return the number of instances of the named type on the segment, or undef if the type is invalid. (cpan.org)
  • basis
  • Below a generic process-data model is given for the whole process of segmenting and positioning as a basis of deciding on the most effective marketing strategy and marketing mix . (wikipedia.org)
