  • 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.

  • 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)

  • 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.

  • Clinical applications of optical fundus imaging technology

    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.
