Analysis of the causes of high intraocular pressure after implantation of V4c implantable contact lens / 国际眼科杂志(Guoji Yanke Zazhi)

@#High intraocular pressure is the most concerned complication of the implantation surgery of V4c implantable contact lens(ICL). According to the appearance time of intraocular pressure elevation, it can be divided into three periods: the early period(1wk after surgery), the middle period(1-4wk after surgery)and the late period(1-3mo after surgery). During the early period, the intraocular pressure increase is mainly caused by the residue of the intraoperative viscoelastic. In the middle period, the application of the hormone drugs results the elevation of the intraocular pressure. Furthermore, during the late period, persistent increasing of the intraocular pressure may cause the secondary glaucoma. Identifying the mechanism of different periods of intraocular pressure rise correctly and thus formulating a reasonable treatment plan, is of great significance for the prevention of glaucoma and other long-term vision threatening complications. Therefore, this article reviews the appearance time and mechanism of the intraocular pressure rise after surgery.

Congenital Glaucoma from Sturge-Weber Syndrome: A Modified Surgical Approach

Sturge-Weber syndrome (SWS) is a rare congenital neurocutaneous disorder that causes congenital glaucoma. Previous experiences have shown that drainage procedures are often required to control associated glaucoma. The conventional surgical approach in trabeculectomy carries a significant risk of intraoperative expulsive hemorrhage. Here, we describe a modified approach of the conventional trabeculectomy technique, which may lower the risk of expulsive hemorrhage. A viscoelastic device was employed to maintain a steady intraocular pressure throughout the procedure. Details of the surgical technique and material used are described. One patient with congenital glaucoma associated with SWS underwent a successful trabeculectomy using the modified technique. Postoperative intraocular pressure was successfully reduced and no intraoperative complications occurred. We describe a successful case of trabeculectomy in a SWS case where a modified technique was applied.
