Occlusion therapy for amblyopia, a historical report from 9th century Persian scholar, Ali ibn Sahl ibn Rabban al-Tabari (838–870 CE)

ABSTRACT

Introduction

This study reevaluates the historical origins of occlusion therapy for amblyopia, focusing on the contributions of the 9th-century Islamic scholar, Ali ibn Sahl ibn Rabban al-Tabari (838–870 CE).

Methods

The investigation delved into al-Tabari’s writings, particularly ”Firdous al-Hikma,” to extract insights into his approach to addressing reduced vision in one eye.Additionally, the study examined subsequent advancements in occlusion therapy by scholars such as Thabit ibn Qurrah and Rhazes, building upon al-Tabari’sfoundational work.

Results

Al-Tabari’s reports contain significant insights into occlusion therapy for amblyopia, predating commonly attributed origins of the treatment. Within ”Firdous al-Hikma,” he outlines methods for addressing reduced vision, advocating for the covering of the healthier eye to promote the function of the weaker eye. These findings highlight the pioneering efforts of al-Tabari and his contemporaries in the Islamic civilization and challenge the conventional narrative surrounding the history of occlusion therapy. Subsequent advancements by scholars such as Thabit ibn Qurrah and Rhazes expanded upon al-Tabari’s work, advocating for similar therapeutic approaches within the Islamic civilization. Their contributions further solidified the practice of occlusion therapy, laying the groundwork for its continued evolution and refinement in subsequent centuries.

Discussion

Al-Tabari’s contributions to occlusion therapy underscore the rich heritage of scientific inquiry in theIslamic civilization during the medieval period. This historical perspective sheds light on the diverse contributions to medical knowledge and practice outside of Western contexts and emphasizes the importance of recognizing and honoring these contributions in the broader history of medicine.
