The science of dacryology – Need of the hour

摘要

Dacryology is a science that deals with the lacrimal systemof the human body. The first mention of lacrimal system datesback to the Code of Hammurabi (2250 BC) which describedan incision for the infected lacrimal sac. Subsequently, theancient Egyptian classic, Ebers Papyrus (1500 BC) detailsthe measures to treat lacrimal sac infections.
