ObjectiveTo explore the application effect of itinerant strengthening post in ophthalmic day operating room.MethodsIn June 2019 (before the establishment of the itinerant strengthening post) and January 2020 (after the establishment of the itinerant strengthening post), satisfaction of 21 ophthalmic surgeons in the ophthalmic day operation room of the West China Hospital of Sichuan University on intraoperative nursing cooperation, and coping ability scores of operation in key links, satisfaction with scheduling and workload, as well as complaints and accusations received by surgeons of 15 ophthalmological nurses in the ophthalmic day operation room of the West China Hospital of Sichuan University were collected. The total volume of eye day surgeries and the length of the day operating room open in the second half of 2018 and 2019 were retrospectively collected.ResultsAfter the establishment of the itinerant strengthening post, the coping ability score of operation in key links of ophthalmological nurses was improved [(3.28±0.72) vs. (4.67±0.72), P<0.01]. In terms of surgeons’ satisfaction with intraoperative nursing cooperation, with the exception of aseptic operation, the other items were improved (P<0.05). The surgical nurses’ satisfaction with scheduling and workload [(3.30±0.77) vs. (4.47±0.67), P<0.01]; nurses’ complaints and accusations received by surgeons [(3.60±1.18) vs. (2.33±0.82), P<0.01] were improved. The volume of eye day surgery from July to December 2019 increased by 6.58% over the same period in 2018, and the average open time of the operating room increased by 1.88%.ConclusionThe setting up of itinerant strengthening posts in the ophthalmology day operation room is conducive to strengthening the strength and business guidance of the nurses’ key links in the operation room in a timely and effective manner. It can optimize the allocation of human resources in the operating room as much as possible when the existing nursing staff is in short supply, and improve the quality and efficiency of ophthalmic surgery nursing, which is worthy of promotion and application.
Objective To investigate the characteristics of ultrasonogram of eyes with silicon oil tamponade. Methods Forty-seven patients (47 eyes) who had undergone the operation of silicon-oil removing were examined by A-(to determine the length of ocular axis) and B-scan before and after the operation respectively. The length of ocular axis and cubage of vitreous chamber were detected and the characteristics of the ultrasonograms were observed according to the default parameters of ultrasonograph. Results The results of A-scan showed that the preoperative axial length was 1.465 times of the postoperative one in the eyes without lens, and 1.284 times in eyes with lens; after modified the parameter according to the acoustic velocity, the preoperative axial length was (0.78±0.34) mm longer than the postoperative one in the eyes without lens, and (0.56±0.32) mm in eyes with lens. The results of A-scan showed that the cubage of vitreous chamber enlarged obviously in eyes with silicon oil tamponade, and the acoustic features included complete filling and partial filling according to the amount of silicon oil. Several arc echoes at the posterior segment of eye were detected in the silicon-oil-filling eyes with retinal detachment. Conclusion In the silicon-oil-filling eyes with lengthened ocular axis, the characteristics of B-scan images are affected by acoustic velocity through silicon oil, the amount of silicon oil capacity and the emulsification of silicon oil.

Ultra-wide field fundus autofluorescence (FAF) imaging is a new noninvasive technique with an imaging range of about 200 °. It can detect peripheral retinal lesions that cannot be found in previous FAFs and more objectively reflect intracellular content and distribution of lipofuscin in the retinal pigment epithelium (RPE) and RPE cell metabolic status. The ultra-wide field FAF can find the abnormal autofluorescence (AF) in the peripheral retina of the eyes of age-related macular degeneration (AMD), and different AF manifestations may have an impact on the diagnosis and treatment of the different AMD subtypes. It is helpful to evaluate subretinal fluid in the eyes of central serous choroidal retinopathy and can accurately detect the changes in the outer retina of the eyes without subretinal fluid. It can help to determine the type of uveitis and fully display the evolution of the disease. It can also assess the peripheral photoreceptor cell layer and RPE in patients with retinal dystrophy and retinitis pigmentosa, and comprehensively evaluate their retinal function and monitor the progress of disease. It can also assist in the evaluation of the short-term efficacy and RPE cell function after the scleral buckling surgery for patients with rhegmatogenous retinal detachment. In the future, ultra-wide field FAF may change the knowledge and intervention strategy of ocular fundus diseases and promote the clinical and scientific research in this field.
Objectives To evaluate the quality of ophthalmic clinical practice guidelines in China by using the AGREE Ⅱ instrument. Methods CBM, CNKI, VIP, and WanFang Data databases were electronically searched to collect Chinese guidelines for ophthalmology from inception to December 2017. Three reviewers independently evaluated the included guidelines using the AGREE Ⅱ instrument. Results A total of 60 Chinese clinical guidelines for ophthalmology were included. The average scores of the six domains including scope and purpose, stakeholder involvement, rigorism of development, clarity of presentation, applicability and editorial independence were 66.4%, 24.6%, 13.5%, 67.4%, 14.5%, and 19.3%, respectively. The guidelines published from 2013 to 2017 scored higher than those published previously in all areas except for domain 4 clarity of presentation. Conclusions The quality of current ophthalmic clinical practice guidelines in China is low, and there is still a big gap between them and the international guidelines. Guidelines developers should place more emphasis on developing regulations to improve stakeholder involvement, rigorism of development, applicability and editorial independence.
Ultra-wide-field fluorescein angiography (UWFA) can obtain very wide retinal images (up to 200°), and is a very helpful tool to detect peripheral retinal lesions which cannot be found by other imaging methods. Analyzing the characteristics of the UWFA images may improve our understanding, treatment outcomes and management strategies of ocular fundus diseases. However this technology is still in its premature stage, there is still a lot of work to be done to improve its clinical application and study the characteristics and clinical meanings of these peripheral retinal lesions.
