目的：研究钝性眼外伤对视力和视网膜神经纤维层(RNFL)的影响。

方法：前瞻性观察研究。收集2018-08/2019-07在Hind医学科学研究所眼科就诊的因道路交通事故(RTA)导致的钝性眼外伤病例。纳入患者年龄20～65岁。记录患者色觉、对比敏感度和最佳矫正视力(BCVA)，并使用OCT分析其RNFL厚度。

结果：本研究共纳入108例患者，分为观察组(54例，RTA患者)和对照组(54例，眼科门诊患者)。平均年龄为43±2.3岁，其中观察组女性11例(20.4%)，男性43例(79.6%)。RTA后初诊时，两组间左右眼色觉、对比敏感度和BCVA差异有统计学意义。随访3mo后，两组间仅对比敏感度有显著差异，色觉及BCVA变化不明显。同样，两组间基线RNFL平均厚度存在显著差异，但随访3mo后，RNFL平均厚度仅在颞上象限有显著差异。

结论：RTA或钝性眼外伤可导致持续的RNFL变薄和视力下降。

METHODS: A prospective observational study was done on the patients of a road traffic accident(RTA)having blunt trauma injury of the eye from august 2018 to July 2019 at the Department of Ophthalmology, Hind Institute of Medical Sciences, Barabanki. Patients between the age group of 20 to 65 years undergoing RTA with ocular complaints were included in this study. Colour vision, contrast sensitivity, and best-corrected visual acuity(BCVA)were recorded, RNFL analysis was done through OCT.

RESULT: A total of 108 patients were enrolled in this study and were grouped as 54 cases and 54 controls. The mean age was 43±2.3 years with 11(20.4%)females and 43(79.6%)males in the case group. At initial visit after RTA, the difference between color vision, contrast sensitivity and BCVA between right and left eyes of cases and controls were significant. After a follow up of 3mo only significant difference was noted in contrast sensitivity between cases and control groups. Change in color vision and BCVA after 3mo was insignificant. Similarly, an initial significant difference was noted in mean RNFL thickness between cases and control groups, but after follow up of 3mo mean RNFL thickness difference was significant only in superior and temporal quadrants.

CONCLUSION:RTA or blunt trauma of eye can lead to persistent RNFL thinning and decreased visual function.
