To evaluate factors influencing early post surgical ocular hypertension after phacoemulsification.
Records were collected for patients who had uncomplicated phacoemulsification with IOL implantation in the bag. Aspiration of the viscoelastic was performed at the conclusion of surgery. Patients with previous ocular surgery, high myopia, or glaucoma were excluded. Intraocular pressures were measured at six hours (+/-2) postoperatively. Following factors were analysed
26% of the patients had an ocular pressure equal or higher than 21 mmHg. Among the factors we analysed, pilocarpine injection was the only one to produce significant decrease in postoperative ocular pressure.
The acute postoperative IOP increase following phacoemulsification is presumably the result of trabecular obstruction by viscoelastic material. However it can occur despite meticulous evacuation of viscoelastic, which could be dependent upon the material's viscosity, and IOL material and design. Postoperative ocular hypertension is not related to ultrasonic duration. Intracameral injection of pilocarpine significantly reduces the incidence of postoperative intraocular pressure increase.
Early postoperative ocular hypertension can be observed with different kinds of viscoelastics and IOL. Meticulous evacuation of viscoelastic from anterior chamber, although necessary does not always prevent this early complication. Intracameral injection of pilocarpine can reduce its incidence.
评估影响白内障超声乳化术后早期高眼压的因素。
收集在囊袋内植入人工晶状体的无并发症白内障超声乳化手术患者的记录。手术结束时进行粘弹剂抽吸。排除既往有眼部手术史、高度近视或青光眼的患者。术后6小时(±2小时)测量眼压。分析以下因素。
26%的患者眼压等于或高于21mmHg。在我们分析的因素中,毛果芸香碱注射是唯一能使术后眼压显著降低的因素。
白内障超声乳化术后急性眼压升高可能是粘弹剂阻塞小梁网所致。然而,尽管仔细清除了粘弹剂,仍可能发生眼压升高,这可能取决于粘弹剂的粘度、人工晶状体材料和设计。术后高眼压与超声持续时间无关。前房内注射毛果芸香碱可显著降低术后眼压升高的发生率。
不同类型的粘弹剂和人工晶状体均可导致术后早期高眼压。尽管从前房仔细清除粘弹剂是必要的,但并不总能预防这种早期并发症。前房内注射毛果芸香碱可降低其发生率。
