非接触广角观察系统在玻璃体视网膜手术中的应用和进展

广角观察系统(wide-angle viewing system)作为玻璃体手术中重要的辅助装置，通过此装置可以清晰地观察到全眼底视野，使玻璃体视网膜手术更加快捷、安全和有效，在眼科手术治疗中，具有很高的应用价值。本文通过对近年来，广角观察系统在玻璃体视网膜手术中的应用和发展进行研究，总结出非接触广角观察系统在临床上的发展优势，并指出其不足之处，以期望非接触广角观察系统在玻璃体手术中的应用得到更好的发展。

Application and development of non contact angle-wide viewing system in vitreous retinal surgery

Wide-angle viewing system as an important auxiliary device can clearly observe the whole fundus field of vision in vitreous surgery, which enable vitreoretinal surgery more efficient, safer and more effective. So it has very high application value in ophthalmologic operation. In this paper, we studied the development and application of wide-angle viewing system in vitreoretinal surgery in recent years, from which we summed up the advantage of non-contact wide-angle viewing system in clinical field, and pointed out the shortcomings. The ultimate goal is to make the non-contact wide-angle viewing system better applied in vitreous surgery.
