[Interdisciplinary diagnostics for examination of lacrimal disorders].

The ophthalmologist is the primary consultant for patients with disorders of the lacrimal duct. The basic examination includes inspection and slit-lamp microscopy of the ocular surface and its adnexa as well as irrigation of the lacrimal pathway. For further treatment, interdisciplinary examination methods offer precise diagnostic findings. Good cooperation among ophthalmologists, otorhinolaryngologists, and radiologists can be highly beneficial for the patient. Rhinogenic causes of lacrimal obstruction can be found by rhinoscopy and nasal endoscopy. Further information is gained by radiologic imaging, which offers dynamic pictures and a good overview of the lacrimal system and neighbouring structures. Lacrimal endoscopy allows direct viewing of the causes of stenosis. These precise and complete diagnostics make consultation easier, especially regarding new minimally invasive surgical techniques.
