Ex-PRESSTM青光眼微型引流器(以色列Optonol公司生产)是一种由不锈钢制作的,用于青光眼手术的小型装置(图1)。其设计原本是用于在结膜瓣下从角膜缘插入前房治疗青光眼,或用于青光眼白内障联合手术者。这种手术相对简单,可在5 分钟内完成,但将其直接置于结膜下,可导致早期持续性低眼压以及晚期结膜糜烂,目前多已被弃用。作者对植入方法进行了改进,即将Ex-PRESS引流器置于巩膜瓣下面。其优点是巩膜瓣可对从引流器引流房水提供阻力,且能保护结膜。
The Ex-PRESSTM Glaucoma Mini Drain (manufactured by Optonol Israel) is a small device made of stainless steel for glaucoma surgery (Figure 1). Its design was originally intended to be used to insert glaucoma from the limbus under the conjunctival flap for the treatment of glaucoma, or for glaucoma and cataract surgery. This procedure is relatively simple and can be completed in 5 minutes, but placing it directly under the conjunctiva leads to early persistent low intraocular pressure and advanced conjunctival erosion, which is currently largely deprecated. The authors modified the implantation method by placing an Ex-PRESS device under the scleral flap. The advantage is that the scleral flap provides resistance to draining aqueous humor from the drainer and protects the conjunctiva.
