  • Progression and challenge of therapeutic strategies in neovascular age-related macular degeneration

    Choroidal neovascularization (CNV) is the key characteristic of neovascular age-related macular degeneration (nAMD), and the effective therapy is intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents based on clinical and basic research. In the meantime the challenge is how to further improve the inhibiting effect for CNV and visual function of anti-VEGF treatment on nAMD. The new strategy and drug delivery devices for anti-VEGF treatment will optimize the clinical scheme. From bench to bedside, the research on targeted treatment of angiogenesis brings the bloom of nAMD medical therapy.

  • The research status and development trends of brain-computer interfaces in medicine

    Brain-computer interfaces (BCIs) have become one of the cutting-edge technologies in the world, and have been mainly applicated in medicine. In this article, we sorted out the development history and important scenarios of BCIs in medical application, analyzed the research progress, technology development, clinical transformation and product market through qualitative and quantitative analysis, and looked forward to the future trends. The results showed that the research hotspots included the processing and interpretation of electroencephalogram (EEG) signals, the development and application of machine learning algorithms, and the detection and treatment of neurological diseases. The technological key points included hardware development such as new electrodes, software development such as algorithms for EEG signal processing, and various medical applications such as rehabilitation and training in stroke patients. Currently, several invasive and non-invasive BCIs are in research. The R&D level of BCIs in China and the United State is leading the world, and have approved a number of non-invasive BCIs. In the future, BCIs will be applied to a wider range of medical fields. Related products will develop shift from a single mode to a combined mode. EEG signal acquisition devices will be miniaturized and wireless. The information flow and interaction between brain and machine will give birth to brain-machine fusion intelligence. Last but not least, the safety and ethical issues of BCIs will be taken seriously, and the relevant regulations and standards will be further improved.

  • Brief history, global trends, and Chinese mission of unilateral biportal endoscopy technique

    The current unilateral biportal endoscopy (UBE) technique was originated from Argentina and developed in South Korea, which was rapidly growing and popularizing in China. The adoption of spinal endoscopy, using small cameras placed inside body with continuous water irrigation, providing better surgical field with less tissue dissection and quicker recovery for patients. As with other disciplines, the use of spinal endoscopy in spinal surgery will become increasingly widespread. UBE technique will promote the popularization of spinal endoscopy in China with monoportal endoscopy technique. At the same time, biportal endoscopy has better expansibility, the application of accessory incision may provide solution for more complicated spinal disease. Chinese spine surgeon should better understand the trends in spinal endoscopy, seize the opportunity of the rapidly evolving in spinal healthcare, and to promote the popularization of UBE across the globe.

  • 糖尿病黄斑水肿玻璃体切割手术及手术后功能评价研究进展

    玻璃体切割手术是治疗糖尿病黄斑水肿(DME)的重要手段之一,手术后功能评价主要包括视功能和形态学评价。视力、视觉电生理仍为视功能的经典评价指标;黄斑厚度和容积改变,视网膜前膜及视网膜下液形成与否为主要形态学观察指标。多焦视网膜电图、微视野、视觉诱发电位、光相干断层扫描、视网膜厚度分析仪和海德堡共焦激光断层扫描等为手术后视功能及黄斑形态学改变提供了科学准确的检测手段,但要做到科学评价尚需考虑到可能的影响因素。(中华眼底病杂志,2008,24:308-312)

  • The application and perspectives of 3D heads-up display viewing system in vitreoretinal surgery

    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.
