Draft:Treat and extend

From Wikipedia, the free encyclopedia

A treat and extend (T&E) protocol of treatment is used for the use of intravitreal anti-VEGF agents that are used for the treatment of specific eye disorders. This treatment protocol is used as alternative to pro re nata (PRN) or as needed. It is typically started with more than three consecutive intravitreal injections every month until disease is relieved, followed by gradual extension of the treatment interval in increments of two to four weeks, up to a maximum interval of twilve to sixteen weeks. When disease activity recurs, treatment intervals will be shortened.[1][2][3][4][5]
