玻璃体切割(简称玻切)是眼科手术中的一大飞跃。它使许多眼病的治疗获得丁突破性进展.但玻切术后眼压常常会异常升高或降低,带来一系列严重的并发疵,若及早发现眼压变化,采取相应措施,可减少并发症的发生,因此玻切术后眼压测量是术后一项重要观察项目.玻切术后为了平覆和防止视网膜脱寓常将惰性气体注入玻璃体腔,即进行气一液体交换(gas—fluid exchange)。气体在眼内聚积,会影响眼压测量的准确性。国外学者对各种型号眼压计在气一液体交换的眼上测量眼压的准确性已作了探讨。我们对这些探讨作一回顾,以供实际工作中选
Vitrectomy (referred to as glass cutting) is a big leap in ophthalmic surgery. It makes many breakthroughs in the treatment of ocular disease, but the intraocular pressure after the operation often abnormally increased or decreased, resulting in a series of serious and complicated defects, if early detection of intraocular pressure changes, take appropriate measures to reduce concurrency Therefore, the intraocular pressure measurement after vitrectomy is an important postoperative observation project after vitrectomy in order to cover and prevent the retina off often inert gas into the vitreous cavity, that is, a gas-liquid exchange (gas- fluid exchange. Accumulation of gas in the eye, will affect the accuracy of intraocular pressure measurement. Foreign scholars on various types of tonometer in the gas-liquid exchange of the eye to measure the accuracy of intraocular pressure has been discussed. We review these discussions for practical work
