一、前列腺素对白内障手术的影响众所周知,前列腺素(Prostaglandin简称PG)在眼内增加时可引起眼内血管通透性增强,血-房水屏障破坏,眼内压升高和瞳孔缩小。内眼手术,特别是白内障手术致眼内组织创伤后,刺激PG的合成与释放增加,在眼内组织中产生PG的生物学效应,使术前用药物散大了的瞳孔重新缩小,妨碍白内障手术的顺利进行,也加重了术后眼部的炎症反应和黄斑部囊样水肿的发生。PG对白内障手术的主要影响综述如下。(一) PG与白内障术中的瞳孔缩小白内障手术的各种术式尽管有不同的变迁,都需要在术前用药物充分散大瞳孔,以便手术的顺利进行。临床实践中,采用现代白内障囊外摘
First, the prostaglandin cataract surgery is well known that prostaglandin (Prostaglandin referred to as PG) increased intraocular pressure can cause increased intravascular vascular permeability, blood - aqueous humor barrier damage, intraocular pressure and miosis. Intraocular surgery, especially cataract surgery caused by intraocular tissue trauma, stimulation of the synthesis and release of PG increase in the biological effects of intraocular tissue PG, the preoperative use of drugs dilated pupil to recapture, hinder cataract The smooth operation, but also increased the postoperative inflammation of the eye and macular cystoid edema. The main effects of PG on cataract surgery are summarized below. (A) PG and cataract surgery in the pupil cataract surgery despite a variety of different surgical procedures require the full use of preoperative medication dilated pupils in order to facilitate the operation. In clinical practice, the use of modern cataract extracapsular extraction
