Glaukos, with help from Dr. Richard Little, an ophthalmologist at the University of California, Irvine, developed an infinitesimal titanium stent that can be implanted in the eye to drain fluid and thus reduce the pressure that leads to glaucoma.

Sponsored: Researchers in France are developing a new smart, connected stent containing sensors that can non-invasively monitor how an artery heals after stent implantation.

In medicine, a stent is a metal or plastic tube inserted into the lumen of an anatomic vessel or duct to keep the passageway open, and stenting is the placement of a stent. There is a wide variety of stents used for different purposes, from expandable coronary,vascular and biliary stents, to simple plastic stents used to allow the flow of urinebetween kidney and bladder. Stent is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis has pathologicallynarrowed a structure such as an artery.

支架Stent)是一種應用於植入型外科手術的管狀器具,以治療體內病變的管道例如血管食道輸尿管等,恢復管道的正常運輸功能。支架一般是永久或半永久植入於患者體內,但亦可以意指手術中用以臨時維持管道形狀的輔助工具。

青光眼的定義一直在更新。早期,人們認為眼壓高,就是青光眼,後來發現了正常人也有高眼壓,而一部分眼壓正常的人們又有青光眼。所以看教科書上關於青光眼的定義隨著人們對這個疾病認識的提高而變化著。青光眼的共同特徵是視神經萎縮視野缺損,病理性的眼壓升高是重要的危險因素之一。
