Objective:To observe the demographic data, disease composition and convenience of remote consultation in ophthalmology.Methods:A retrospective study. From 2015 to 2021, the demographic data, changing trends, disease classification of teleconsultation patients, and hospitals participating in teleconsultation, and the waiting time of patients for teleconsultation was analyzed retrospectively; remote consultation physician level composition and other data was analyzed.Results:During the 7-year period, 1 216 patients with remote consultation were obtained through the platform of the telemedicine center. Among them, there were 680 males and 536 females; the average age was 50.8 years. In 2016 and 2017, the number of patients participating in telemedicine consultations reached a peak of 260 and 221 cases, respectively. Among the ophthalmic diseases, there were 490 cases (40.30%, 490/1 216) of retinal and optic nerve-related diseases, 212 cases (17.43%, 212/1 216) of ocular trauma. 678 cases (56.27%, 678/1 205) of remote consultation waiting time were less than 24 hours, 991 cases (82.24%, 991/1 205) were less than 48 hours. Among the physicians who participated in the remote consultation, there were 733 chief physicians (60.3%, 733/1 216) and 466 deputy chief physicians (38.3%, 466/1 216).Conclusions:During the seven-year period from 2015 to 2021, there are relatively few patients with ophthalmology teleconsultation; retinal and optic nerve-related diseases accounted for a high proportion. Remote consultation has high convenience.

Objective:To analyze the research hotspots and trends of swallowing disorders in patients with head and neck tumors both domestically and internationally, to provide reference for future research directions.Methods:Using the China National Knowledge Infrastructure and Web of Science core collection databases as data sources, research literature related to swallowing disorders in head and neck tumor patients published from January 1, 2013, to December 31, 2022, was retrieved. A knowledge graph was drawn using Cite Space 6.2 R3 software, and the graph was interpreted and analyzed from the aspects of publication volume, publication country, and institution, high-frequency keyword co-occurrence and clustering, and emergent words.Results:A total of 427 English literature were included. The overall number of publications is on the rise. The countries with a high volume of collaborative publications were the United States, Australia, the Netherlands, and the United Kingdom. The top three institutions in terms of publication volume were the University of Queensland in Australia, the University of Newcastle in the UK, and the Amsterdam Institute in the Netherlands. A total of 10 cluster clusters and 25 prominent keywords were obtained. The hot topics of research and analysis were "swallowing dysfunction" "associated complications" and "long-term effects", with the forefront being "radiation-induced dry mouth syndrome".Conclusions:Compared to foreign countries, China currently has a relatively small number of publications, loose cooperation between research authors and institutions, and a need for more diverse disciplines and research methods. Focusing on hot topics and cutting-edge content, exploring the mechanism of swallowing disorders in head and neck tumors, implementing targeted interventions, strengthening health education, predicting postoperative dangerous complications, constructing feasible nursing plans, and improving the quality of life of patients will become the development trend of future research.
