摘要:

目的 观察巩膜外硅胶海绵垫压术和巩膜外环扎联合硅胶垫压术后眼球结构的改变及对眼压的影响。设计 回顾性病例系列。研究对象 孔源性视网膜脱离住院手术治疗患者64例64眼,其中接受巩膜外单纯硅胶海绵垫压术25眼(海绵组),巩膜外环扎联合硅胶垫压术39眼(联合组)。方法 手术前,术后1周、1个月及3个月应用A型超声仪、超声生物显微镜(UBM)对眼球生物参数检测,非接触眼压计检测眼压。主要指标 眼压、角膜厚度、角膜曲率、前房深度、晶状体厚度、睫状体厚度、房角开放距离和小梁虹膜夹角。结果 术后3个月时64眼全部视网膜解剖复位。眼压、角膜厚度、角膜水平曲率、角膜垂直曲率、晶状体厚度、睫状体厚度,术后1周与术前相比显著增加(P均<0. 05)。海绵组术后1个月和3个月眼压与术前相比无显著性差异,而联合组术后3个月眼压(15.41±2.58)mmHg与术前(13.66±3.16)mmHg相比有显著性差异(P=0.009)。海绵组和联合组角膜垂直曲率术后1周分别为(45.03±1.08)D、(44.47±0.90)D(P=0.027)。结论 巩膜外硅胶海绵垫压术和巩膜外环扎联合硅胶垫压术对角膜、前房及房角等眼球结构的早期影响较明显;巩膜外环扎联合硅胶垫压术对眼压影响持续时间长,应给予关注和干预。(眼科,2017, 26: 30-34)

Abstract:

Objective To evaluate the eyeball structure changes and the influence of intraocular pressure (IOP) after two types of external-route microsurgery (the local buckling and the local buckling received encircling) in patients with rhegmatogenous retinal detachment(RD). Design Retrospective case series. Participants 64 patients (64 eyes) with rhegmatogenous RD were treated with the local buckling (25 eyes) or the local buckling and encircling (39 eyes). Methods Biological data were measured with A-scan and ultrasound biomicroscopy (UBM) and IOP were measured with non-contact tonometry at preoperation, and postoperative1 week, 1 month and 3 months. Main Outcome Measures Intraocular pressure, corneal thickness, corneal curvature, central anterior chamber depth, thickness of lens, ciliary thickness and trabecular-iris angle. Results After 3 months of external-route microsurgery, the retina was anatomically reattached in all 64 patients. Compared with preoperative data, IOP, corneal thickness, corneal horizontal curvature, corneal vertical curvature, thickness of lens and ciliary thickness were significantly increased at 1 week after surgery (all P<0.05). The difference of IOP was no statistically significant at 1 month and 3 months after the operation in the local buckling group. On the contrary, it has significantly meaningful changes at 3 months (15.41±2.58 mmHg) to compared with that (13.66±3.16 mmHg) before surgery in the local buckling group (P=0.009). At 1 week after surgery, the corneal vertical curvatures of these two groups were (45.03±1.08) D and (44.47±0.90) D (P=0.027). Conclusions The local buckling and the local buckling combined encircling for rhegmatogenous retinal detachment can early influence eyeball structure significantly, including cornea, anterior chamber and anterior chamber angle. Intraocular pressure is affected for longer duration and should be given attention and intervention. (Ophthalmol CHN, 2017, 26: 30-34)
