We\u2019ve put together some commonly asked questions about Verdye, Indocyanine Green and the use of ICG. Verdye, as it is known in most European territories, is a sterile, lyophilized green powder containing the active ingredient Indocyanine Green (ICG).<\/p>\n Following intravenous (I.V.) injection, ICG or Indocyanine Green binds rapidly to plasma proteins and remains within the blood vessels. It has a half-life of 3 to 4 minutes and is removed from circulation exclusively by the liver and then eliminated through the bile. It does not undergo metabolism.<\/span><\/p>\n Indocyanine Green (ICG) is dissolved using sterile water for injection and is for single use only.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t Indocyanine Green (ICG), is cleared exclusively through the liver and then excreted through the bile. It does not undergo metabolism. It has an excellent safety profile and adverse reactions occur very rarely (<1\/10,000). Indocyanine Green for Ophthalmic Retinal Angiogram was introduced in 1973. Since then, ICG for ophthalmic retinal angiogram can be used to investigate retinal disorders including Macular\/Choroidal\/Outer Retinal Disorders.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t Indocyanine Green Angiography (ICGA) is the gold standard in diagnosing a number of serious eye conditions and is a ICGA is particularly useful in the differential diagnosis of<\/p> Videoangiogram recordings via Scanning Laser Ophthalmoscopy allow for rapid identification of high contrast images. 25mg\/10ml Sterile Water dilution. 5ml bolus intravenous injection.<\/p> For more information go to the Verdye Product Information<\/a>.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t Early Phase: 60 Seconds \u2013 Choroidal Leakage\/Irregular Choroidal Capillaries \/ Choroidal filling defect<\/p> Mid Phase: 1-3 Minutes<\/p> Late Phase: 15-45 Minutes Diagnostic Green Verdye Product Information<\/a>.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t Applications where ICGA is considered superior include<\/p>\n There are a number of reasons including:<\/p> FA images Retinal Circulation whereas ICG images Choroidal circulation.
