According to the Egyptian historian Ibn-Qefti, (568 – 648 AH), the Gondishapur physicians were considered more advanced than the Greek and Indian methods, because of the development of a new system of diagnosis and treatment that was developed there.
The physicians were required to pass special examinations and obtain a license in order to practice medicine.

The most distinguished physicians of Gondishapur were members of two Christian Iranian families: Buhktishu (in Syriac means Jesus had saved) and Masuyeh (in Latin Mesue). The Buhktishu family practiced at the school for more than two centuries.

In 765 AD Jurjis Buhktishu, the chief of Gondishapur Hospital was summoned to Baghdad to treat the Abbasid Caliph al-Mansour. (d.158 AH /775 AD), and so, an official connection between the Gondishapur physicians and Baghdad was established for the first time. Then, in subsequent years, more medical scholars from Iran migrated to Baghdad. They played an important role in the
development of Islamic medicine. They wrote a variety of books on medicine and translated medical Pahlavi and Syriac texts into Arabic. For instance, Yuhanna, the son of Masuyeh was a reputed physician who worked in Baghdad during the first half of the 9 century AD. He wrote the first Arabic treatise on ophthalmology

At Gondishapur School, medical books including Greek texts were translated into Syriac or Pahlavi mostly by the Nestorian physicians. Hunayan-Ibn-Ishaq (808 – 873 AD), known as Johannitus, was born in al-Hira in Iraq who studied medicine at the Gondishapur School and then in Alexandria. He was an active translator of Galen’s medical works into Arabic.
