FIELD: medicine.
SUBSTANCE: invention relates to medicine, specifically to ophthalmology. Lachrymal passages are probed with double endoscopic control by a lacrimal endoscope and an endorinoscope. Control of manipulations, including elimination of lachrymation obstruction by means of elastic part of intravenous catheter 18G, put on introduced part of lacrimal endoscope with diameter of 0.65 mm, angle of view 65°, is performed through an endoscope optical system. Nasal cavity is monitored and manipulated therein through a HopkinsII endorinoscope of diameter 2.7 or 4.0 mm, a viewing angle of 30°.
EFFECT: method reduces risk of complications when probing lachrymal passages by double endoscopic control.
