【摘要】：目的评估白内障术前联合检查对术后视力预测的准确性、有效性和实用性。方法对252例262眼的不同类型白内障患者在手术前按统一检查项目做好相关检查,主要包括手术前裸眼和矫正视力、瞳孔反射、色觉检查、散瞳前置镜眼底检查、晶状体核硬度、眼压、角膜曲率径检查、眼科A超眼轴长度的测量、B超影像检查、视觉电生理(F-ERG和F-VEP)检查,视网膜计潜视力测定并将这些相关的检查结果结合起来,综合分析判断,最后得出术后预测视力。并将检查结果与术后4周最佳矫正视力(BCVA)对照并做统计分析。结果252例262眼白内障患者通过手术前联合检查预测术后视力和术后4w最佳矫正视力(BCVA)符合率70.45%。结论术前联合检查预测白内障术后视力的结果与术后4w最佳矫正视力(BCVA)的结果基本相符,各检查项目与术后4w最佳矫正视力(BCVA)之间存在显著相关性,能准确、有效地预测白内障手术后视力恢复情况。
[Abstract]:Objective to evaluate the accuracy, effectiveness and practicability of preoperative combined examination in predicting postoperative visual acuity. Methods 252 cases (262 eyes) of cataract with different types of cataract were examined according to the unified examination items before operation, including uncorrected visual acuity, pupillary reflex, color vision, fundus examination of anterior mydriasis, nuclear hardness of lens. Intraocular pressure, corneal curvature diameter, measurement of axial length of ophthalmology A supersonic axis, B-ultrasound imaging, visual electrophysiology (F-ERG and F-VEP), retinal potential visual acuity (RVA), combined with these relevant examination results, and comprehensive analysis and judgment. Finally, the postoperative visual acuity was predicted. The results were compared with the best corrected visual acuity (BCVA) 4 weeks after operation. Results 252 cases (262 eyes) of cataract were diagnosed by combined examination before operation. The coincidence rate of postoperative visual acuity (BCVA) and best corrected visual acuity (BCVA) was 70.45%. Conclusion the results of preoperative combined examination in predicting postoperative visual acuity (BCVA) are basically consistent with the results of BCVA at 4 weeks postoperatively. There is a significant correlation between each examination item and the best corrected visual acuity (BCVA) at 4 weeks postoperatively. It can effectively predict the recovery of visual acuity after cataract surgery.
