摘要
目的通过对视网膜脱离患者行玻璃体切割硅油填充术前后、硅油取出术后传统A超眼球生物测定值的动态对比观察,统计学分析其临床意义。方法对2009年6月至2013年3月在南京军区总医院临床学院眼科动态观察行视网膜脱离手术患者59例61只眼,对患者术前、硅油填充状态、硅油取出后30天3个时间点采用A超屈光模式动态测定眼球生物值,包括:眼轴长度、前房深度、晶状体厚度、玻璃体腔深度,对所测值进行统计学分析。结果(1)A超测量患者术前与硅油填充状态的眼轴长度、前房深度、玻璃体腔深度差异均有统计学意义。(2)硅油填充状态与硅油取出后的眼轴长度、前房深度、玻璃体腔深度差异均有统计学意义。(3)术前与硅油取出后玻璃体腔深度差异有统计学意义。(4)术前与硅油取出后的眼轴长度、前房深度差异均无统计学意义。(5)术前与硅油填充状态、硅油填充状态与硅油取出后的晶状体厚度差异无统计学意义。结论本研究患者术前与硅油取出后的眼轴长度、前房深度差异均无统计学意义,这对硅油取出联合白内障摘除及人工晶状体植入术的患者选择精确人工晶状体度数提供一定的帮助,证明术前A超眼球生物测定值的资料是十分有效的参考。
Objective To compare the biometry measurements of A-scan ultrasound in patients with vitrectomy and silicon oil tamponade, silicon oil removal, and analyze its clinical significance. Methods Dynamic observation was conducted in 61 eyes of 59 patients with retinal detachment by same operator. Measurements were made before operation, silicon oil-filled and silicon oil removal by Ultra scan Digital 2000 contact ultrasound A-scan (Alcon), which included axial length (AL), ante- rior chamber depth (ACD), Lens thickness and crystal thickness. Results There was significant differ- ence in measurement of ALs, ACDs and crystal thickness preoperative and silicon oil-filled measured by A-can ultrasound, respectively. Significant difference of the ALs, ACDs and crystal thickness in silicon oil-filled and silicon oil removal was also found. The crystal thickness measured by A-can ul- trasound preoperative and silicone oil removal, showing significant discrepancy. There was no statisti- cal significance of ALs and ACDs changes preoperative and silicone oil removal. Before and after operation, the difference of lens thickness measured by A-scan ultrasound was not significant. Con- clusions In this study, there is no statistical significance of ALs and ACDs changes before and after operation. The preoperative A-scan biometric data is effective reference for phacoemulsification com- bined silicone oil removal and intraocular lens implantation.
