[Endoscopic diagnosis of the lacrimal drainage system]

Endoscopic study of the lacrimal drainage system is the only way to directly observe the lacrimal sector of the lacrimal drainage system. The first experiments on this subject date from 1979. Recent technological progress has allowed us to test the latest instruments. These experiments have demonstrated the unquestionable progress of endoscopes and their potential contribution to diagnosing lacrimal pathology. However, certain factors still limit their everyday use. Image improvements and low cost will no doubt facilitate its integration in the diagnosis and therapy of the lacrimal drainage system.
