With the rapid development of artificial intelligence (AI), especially deep learning, AI research in the field of ophthalmology has presented a trend of diversification in disease types, generalization in scenarios and deepening in researches. The AI algorithm has showed a good performance in the studies of diabetic retinopathy, age-related macular degeneration, glaucoma and other ocular diseases, yielding up the great potential of ophthalmic AI. However, most studies are still in their infancy, and the application of ophthalmic AI still faces many challenges such as lack of interpretability for results, deficiency of data standardization, and insufficiency of clinical applicability. At the same time, it should also be noted that the development of multi-modal imaging, the innovation of digital technologies (such as 5G and the Internet of Things) and telemedicine, and the new discovery that retina status can reflect systemic diseases have brought new opportunities for the development of ophthalmic AI. Learn the current status of AI research in the field of ophthalmology, grasp the new challenges and opportunities in its development process, successfully realizing the transformation of ophthalmic AI from research to practical application.

ObjectiveTo analyze the increased risks of nursing due to expansion of ophthalmic day surgery indications, and the countermeasures. MethodsWe collected the information in the last three years from January 2012 to December 2014 in the Department of Ophthalmology, including the number of operations, the proportion of cataract patients, patients aged over 70 and under 12 years old, patients with high-risk fall, the number of general anesthesia operations, adverse events, and the data from the satisfaction survey of the patients. All the data were analyzed by statistical method. ResultsDuring the last three years, the relaxation of ophthalmic day surgery indications led to an increased admission rate of high-risk patients, and caused more nursing risk factors. Through the efforts of prevention and care, during the last three years, there were no adverse events, and patients had a satisfaction rate over 90%. ConclusionAlthough the ophthalmic day surgery indication has been relaxed, through the establishment of nursing risk response system by pre-hospital guidance, admission assessment, peri-operative education and follow-up visit, with the continuous improvement of nursing management system and convenient workflow, we can not only improve the work efficiency, but also ensure nursing safety.
ObjectiveTo observe the demographic data, disease composition and convenience of remote consultation in ophthalmology. MethodsA 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. ResultsDuring 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). ConclusionsDuring 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 explore the effect of the feed-forward control on safety nursing of ophthalmologic day surgery patients under general anesthesia. Methods A total of 623 ophthalmologic day surgery patients under general anesthesia were retrospectively selected into the control group, who adapted the routine nursing in the Ophthalmic Day Surgery Center from January to December 2015; a total of 1 210 ophthalmologic day surgery patients under general anesthesia were retrospectively selected into the observation group, who received the feed-forward control of nursing safety management on the basis of routine nursing care from January to December 2016. The incidence rate of the adverse events and potential safety hazards and satisfaction rate were compared between the two groups. Results The incidence rate of the adverse events and potential safety hazards in the observation group (0.83%, 10/1 210) was lower than that in the control group (3.37%, 21/623), the satisfaction rate in the observation group (98.67%) was higher than that in the control group (97.11%), and the differences were statistically significant (P<0.05). Conclusion The application of feed-forward control in the safety care of patients during the ophthalmologic day surgery under general anesthesia can effectively reduce the incidence of adverse events and potential safety hazards, and ensure the safety of medical care.
ObjectiveTo analyze the consistency of diagnostic results using simple and comprehensive reading methods on stereoscopic color fundus photographs of diabetic retinopathy (DR) with diabetic macular edema (DME). Methods450 sets of 7-field stereoscopic color fundus photographs of DR DME were compared to standard fundus photographs of early treatment and DR study group. The pictures were read by two groups of reader with similar experience. Two strategies were used to make the judgments, including simple reading which based on the color fundus photographs only, and comprehensive reading which based on color fundus photographs, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT). 15 parameters were scored, including micro-aneurysms (MA), intra-retinal hemorrhage (IRH), hard exudates (HE), cotton wood spot (CW), intra-retinal microvascular abnormalities (IRMA), neovascularization on optic disc (NVD), neovascularization elsewhere (NVE), optic fiber proliferation (FPD), fiber proliferation elsewhere (FPE), pre-retinal hemorrhage (PRH), vitreous hemorrhage (VH), retinal elevation (RE), retinal detachment of central macular (RDC), venous beading (VB), Venous leak (VL). The reliability was evaluated using weighted κ(κw) statistic values. According to Fleiss statistical theory, κw≥0.75, consistency is excellent; 0.60≤κw < 0.75, consistency is good; 0.40≤κw < 0.60, consistency is general; κw < 0.40, consistency is poor. ResultsThe κw values of these 15 parameters were 0.22-1.00, 0.28-1.00 for the simple reading and comprehensive reading respectively. For simple reading, the consistency was poor for 8 parameters (MA, NVD, NVE, FPE, PRH, IRMA, VB, VL), general for 3 parameters (CW, FPD, VH), good for 2 parameters (IRH, HE) and excellent for 2 parameters (RE, RDC). For comprehensive reading, the consistency was poor for 2 parameters (NVE, VB), general for 6 parameters (MA, IRH, CW, FPE, IRMA, VL), good for 2 parameters (NVD, HE), excellent for 5 parameters (FPE, PRH, VH, RE, RDC). ConclusionThe comprehensive reading has higher consistency to judge the abnormality parameters of the fundus photographs of DR with DME.
