• angiograms
  • With the supplementation of fluorescein angiograms to color fundus photographs, there were statistically significant improvements in the sensitivity for diagnosing stage 2 or worse (p = 0.016), stage 3 or worse (p = 0.008), pre-plus or worse (p = 0.031), and type-2 ROP or worse (p = 0.013) as compared to the consensus reference standard diagnosis. (arvojournals.org)
  • No significant changes in specificity were seen with the addition of fluorescein angiograms to color fundus photographs.For identification of treatment-requiring ROP, there was a statistically significant difference in inter-grader agreement when viewing the color fundus photographs alone versus the color fundus photographs + FA. (arvojournals.org)
  • Most angiograms are done using the Fluorescein dye. (launcestoneye.com.au)
  • angiographic
  • The angiographic apparatus we use has a flash generator, with a rapid regeneration (1 or 2 frames per second), a variable power, from 10 W/sec to 300 W/sec., a wide angle lens (45 ° up to 60 °), two cameras, one for color retinography and the other one, motorized, for the black and white angiography.

  • Awareness of the side effects, adverse reactions, and complications of the contrast agent allow the ophthalmic healthcare team to anticipate, respond quickly, and support the patient before, during, and following the angiographic procedure using fluorescein. (jcahpo.org)
  • capillary
  • Causes of hyperfluorescence: window/transmission (filling) defects leaking defects (i.e. capillary leakage, aneurysm, neovascularization) pooling defects staining abnormal vasculature Causes of hypofluorescence: blocking defect (i.e. blood) filling defect (capillary nonperfusion/blockage) Fluorescein angiography is used by physicians specializing in the treatment of eye diseases (ophthalmologists) to evaluate the vasculature of the retina, choroid, optic disc, and iris.

  • diseases
  • This course will provide an overview of the use of fluorescein for diagnosing eye related diseases and conditions and include appropriate doses for adult and pediatric patients. (jcahpo.org)
  • The technique was first developed in 1927 by the Portuguese physician and neurologist Egas Moniz at the University of Lisbon to provide contrasted x-ray cerebral angiography in order to diagnose several kinds of nervous diseases, such as tumors, artery disease and arteriovenous malformations. (wikipedia.org)
  • Blood
  • In addition, the results of Allen's tests do not appear to correlate with distal blood flow as demonstrated by fluorescein dye injections. (wikipedia.org)
  • perform
  • Radial access technique for angiography can be traced back to 1953, where Eduardo Pereira first cannulated the radial artery to perform a coronary angiogram. (wikipedia.org)
  • digital
  • A series of black-and-white or digital photographs are taken of the retina before and after the fluorescein reaches the retinal circulation (approximately 10 seconds after injection). (wikipedia.org)
  • For all structures except the heart, the images are usually taken using a technique called digital subtraction angiography or DSA. (wikipedia.org)
  • date
  • Since this date, angiography has been taught at the National veterinary school in Toulouse (France). (vin.com)
