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.
Optical imaging technology of ocular fundus, including fundus fluorescein angiography (FFA), optical coherence tomography (OCT) and fundus autofluorescence (FAF), is growing at an unprecedented speed and scale and is integrating into the routine clinical management of ocular fundus diseases, such as diagnosis, treatment, and mechanism study. While FFA allow us to observe the retinal and choroidal blood circulation, OCT and FAF are non-invasive, fast and quantifiable measurement; such techniques show even more unique advantages and are favored tools. All these retinal imaging technologies, together with a variety of retinal function assessments, bring us into the era of big data of ocular fundus diseases. All of these developments are the challenges and opportunities for the operator and user of these fundus optics imaging technologies. In order to improve its clinical applications and allocate resources rationally, we need to understand the optical properties of these retinal imaging technologies, and standardize diagnosis behavior. This is a continuous learning process needs to continue to explore.
The hallmark of the recent latest advances in diagnostic fundus imaging technology is combination of complex hierarchical levels and depths, as well as wide-angle imaging, ultra-wide imaging. The clinical application of wide-angle and ultra-wide imaging, not only can reevaluate the role of the peripheral retina, the classification types and treatment modalities of central retinal vein occlusion, and enhance the reliability of diabetic retinopathy screening, improve the classification and therapeutic decision of diabetic retinopathy, and but also can help guide and improve laser photocoagulation. However we must clearly recognize that the dominant role of ophthalmologists in the diagnosis of ocular fundus diseases cannot be replaced by any advanced fundus imaging technology including wide-angle imaging. We emphasize to use the three factors of cognitive performance (technology, knowledge and thinking) to improve the diagnosis of ocular fundus diseases in China.
Using optical imaging equipment with different wavelength and computer technology, fundus optical imaging diagnostic techniques can record fundus reflected light, auto fluorescence and emitted light after excitation by external light source in order to observe and analyze the structure and pathological process of retina and choroid. Advances in fundus optical image capture technology (including laser, confocal laser, spontaneous auto-fluorescence, multispectral imaging) and storage and analysis technology, promote this field into a high-definition digital imaging era, with features of rapid, non-invasive, wide-angle three-dimensional multi-level integration, dynamic automatic navigation location tracking and combined application of a variety of optical imaging diagnostic techniques. In order to promote clinical and scientific research of ocular fundus diseases, we need to understand the development trend of optical imaging diagnostic technique, interpret the fundus imaging features appropriately, reasonably chose different inspection techniques, establish standardized diagnosis criteria and continue to expand clinical applications.
Neuro-ophthalmology is an interdisciplinary discipline that spans multiple disciplines such as ophthalmology, neurology, and neurosurgery, and plays an important role in ophthalmology. Since the establishment of the Neuro-Ophthalmology Group in 2011, it has shown a good momentum of accelerated development of neuroophthalmology team building, promoting the process of neuroophthalmology standardization and strengthening interdisciplinary cooperation. However, there is still a gap between the level of neuro-ophthalmology in China and that in developed countries, which still cannot get rid of the stage of introduction and imitation. It is still a long way to form neuro-ophthalmology with unique characteristics in China. In the future, we should carry out clinical research while advancing basic research work, and establish a standard training system to strengthen the training of neuroophthalmologists. It is expected that in the next 10 years, China's neuro-ophthalmic diagnosis and research level will be significantly improved, and a number of landmark academic achievements will be achieved, and a number of internationally and domestically renowned neuro-ophthalmologist will be trained to further enhance the international academic status of neuro-ophthalmic research in China.
Objective To design nursing record sheet for day surgery in the Department of Ophthalmology and evaluate its effect through clinical application. Methods The nursing record sheet for day surgery in the Department of Ophthalmology was designed based on the theory of forms and record control, using the method of process analysis and process reengineering and taking into consideration the characteristics of nursing care during day surgery in the Department of Ophthalmology. The adverse event rate in nursing for ophthalmologic surgery and the satisfaction rate of operating room nurses were calculated before and after the application of this record sheet. Results From July to October 2015, the Department of Ophthalmology was involved in 9 cases (7.96%) of adverse events resulting from drawbacks of the nursing record design or mistakes in recording. From November 2015 to February 2016, the Department of Ophthalmology was involved in only 1 case (1.28%) of advense event resulting from defect caused by nuring record sheet; the difference was significant (P < 0.05). From July to October 2015, the satisfaction rate of oph thalmologic nurses before using the nursing record sheet was 54.33%, which was significantly improved to 98.71% from November 2015 to February 2016 after the utilization of the nursing record sheet. Conclusion The nursing record sheet for day surgery in the Department of Ophthalmology has been appropriately designed and is easy to use, which can improve the quality of surgery nursing as well as the satisfaction of operating room nurses.
