Optical coherence tomography (OCT) has developed from time-doma in into Fourier-domain OCT (FD-OCT) which indicates clearer details and higher resolution of images. FD-OCT can indicate the structure and pathological changes of each retinal layer, and reveal the retinal external limiting membranes and changes of inner- and outer-segment of visual cells by 3D solid reconstruction. FD-OCT not only provide detailed information of the images for the clinical diagnosis, but also help us investigting the characteristics and pthological mechanisms of ocular fundus diseases, which lead us to a new era of technology of observation on ocualr fundus diseases. In the application, we should pay attention to the significance of different colors of OCT images, and focus on the cohenrence of the position in the image acquistion during the follow-up period. Dynamic observation on the lesions by FD-OCT and aggregated anaylsis of resutls of several imageological examination would be the development direction of imageological examination of ocular fundus diseases.
Objective
To find convenient methods for remote consultation of images of ocular fundus diseases.
Methods
A remote consultation system composed of internet was set up.The con sultation information,including images,words and figures,was published on intern et as web pages,so that the consultants would get the notice and the appointment by email.After reading the information on line,the consultants gave their opinions back to internet.
Results
The remote consultation system of images of ocular fundus diseases was setted up and managed successfully,and 23 patients had been diagnosed by this system.
Conclusion
The system which has clinical practicality is a simple,quick,effective and economic method for remote consultation of images of ocular fundus diseases.

Currently, coronavirus disease 2019 (COVID-19) is still widely prevalent around the world, leading to a major threat to the global public health. COVID-19 mainly involves the respiratory system, but extrapulmonary manifestations including that of the nervous system also exist in the setting of COVID-19. Misdiagnosis and delayed treatment of the disease may easily cause when ocular, especially neuro-ophthalmological symptoms are the first symptoms in early COVID-19, as the neuroophthalmological manifestations are rarely reported. First-line clinicians need to ask about not only respiratory symptoms such as fever, cough and sore throat, but also diplopia, impaired vision, eye motion pain, abnormal gait or other neurological deficits at the first reception, as these extrapulmonary manifestations are often signs of serious infection. The neuroophthalmological manifestations and possible underlying etiology of COVID-19 were summarized in this review, hoping to provide an early identification and effective treatment of COVID-19 for clinicians. More extensive studies are needed in the future to confirm the causal relationship between COVID-19 and neuroophthalmological disease to provide a sufficient basis for a comprehensive understanding of COVID-19.
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.
There has been ongoing progress in the new technique and equipment in vitreoretinal surgery in recent years, contributing to the improvement of treatment of various vitreoretinal diseases. The application of 3D heads-up display viewing system (3D viewing system) has been one of the most fascinating breakthroughs in vitreoretinal surgery. Unlike the traditional method in which the surgeons have to look through the microscope eyepieces, this system allows them to turn their heads up and operate with their eyes on a high-definition 3D monitor. It provides the surgeons with superior visualization and stereoscopic sensation. And increasing studies have revealed it to be as safe and effective as the traditional microscopic system. Furthermore, the surgeons can keep a heads-up position in a more comfortable posture and lesson the pressure on cervical spine. Meanwhile, 3D viewing system makes it easier for the teaching and learning process among surgeons and assistants. However, there are still potential disadvantages including the latency between surgeon maneuver and visualization on the display, learning curves and cost. We hope that the 3D viewing system will be widely used and become a useful new tool for various vitreoretinal diseases in the near future with rapid development in the technology and constant upgrade of the system.
Obstructive sleep apnea hypopnea syndrome (OSAHS) is a disease in which apnea and hypopnea occur during sleep, and the main symptoms are sleep snoring. OSAHS is not only closely related to the occurrence of various eye diseases, but also the severity of OSAHS can affect the progression of related eye diseases. At present, continuous positive airway pressure (CPAP) is an effective means to treat OSAHS, and the progression of related eye diseases has been improved correspondingly after CPAP treatment. In the future, it is necessary to further study the pathogenesis of OSAHS and enrich the research evidence of the association between OSAHS and eye diseases, so as to provide more comprehensive theoretical evidence for the prevention and treatment of OSAHS-related eye diseases.
In recent years, more and more new diagnostic and examining techniques are popularized, which improves the level of ocular fundus disease diagnosis and treatment. Because of the uneven distribution of diagnostic and therapeutic instruments resources, low level of application techniques, and different professional level of the doctors, the improvement and development of the application of the equipments and level of the diagnosis and treatment were inhibited. Appropriate understanding and applying basic diagnostic techniques of ocular fundus disease and comprehensive promoting the professionalsprime; levels are an urgent problem needs to be solved.
