“…Given the particularity of our patients, we used lacrimal endoscopy and 80‐MHz UBM for further examinations. Studies 1,12,13 have shown that lacrimal endoscopy can clearly and effectively elucidate changes in the mucous layer of the lacrimal canaliculus in vitro as well as in vivo. Mucopurulent discharges, cobblestone‐like changes, fibrous hyperplasia, and concretions 1 are common pathological changes of the canaliculus under lacrimal endoscopy.…”

Lacrimal canaliculitis (LC) is a rare infection of lacrimal passage, which is usually late diagnosed or misdiagnosed. Traditional lacrimal system tests barely provide a clear and definite understanding of the pathological changes in lacrimal passage. We presented three patients with asymptomatic and atypical symptoms who were misdiagnosed and were eventually diagnosed with chronic LC with assistance of 80‐MHz ultrasound biomicroscopy (80‐MHz UBM) and lacrimal endoscopy. To our knowledge, the mutual assistance of above two techniques diagnosing LC has never been reported, it can provide better images and observations of the canaliculus from the inside out and can guide the differential diagnosis.

Lacrimal plug is an effective and widely therapeutic strategy to treat dry eye. However, almost all commercialized plugs are fixed in a certain design and associated with many complications, such as spontaneous plug extrusion, epiphora, and granuloma and cannot be traced in the long‐term. Herein, a simple in situ forming hydrogel is developed as a tracer and degradable lacrimal plug to achieve the best match with the irregular lacrimal passages. In this strategy, methacrylate‐modified silk fibroin (SFMA) is served as a network, and a self‐assembled indocyanine green fluorescence tracer nanoparticle (FTN) is embedded as an indicator to develop the hydrogel plug using visible photo‐crosslinking. This SFMA/FTN hydrogel plug has excellent biocompatibility and biodegradability, which can be noninvasively monitored by near‐infrared light. In vivo tests based on dry eye rabbits show that the SFMA/FTN hydrogel plug can completely block the lacrimal passages and greatly improve the various clinical indicators of dry eye. These results demonstrate that the SFMA/FTN hydrogel is suitable as an injectable and degradable lacrimal plug with a long‐term tracking function. The work offers a new approach to the development of absorbable plugs for the treatment of dry eye.
