I wouldn't say it gets completely ignored. Pretty much everything I read about the subjects mentions how the Muslims translated into Arabic, expanded upon, corrected and were influenced by the work of earlier cultures.

Much of the Islamic scholarship at the time revolved around gaining a greater understanding of the creation of God as a means to draw nearer to God.
In addition a lot of scholars in the major Islamic centres weren't even Muslim. For example, the conquest of the Iberian Peninsula (welcomed by the local Jewish population) ushered in a Jewish Golden Age which produced Maimonides, one of the greatest Jewish scholars of the time.
