Abstract

PURPOSE

To determine the factors affecting the visual outcome after surgical repair of limbal corneal lacerations at a tertiary eye care center in South India.

METHODS

A retrospective analysis of patients diagnosed with limbal tears between 2011 and 2021 was conducted. Demographic information such as age, gender, cause of injury, and size of the laceration was recorded. Comprehensive ocular examination was performed, including gentle B scan evaluation whenever not contraindicated for detailed posterior segment evaluation. Only those cases with a minimum follow-up of one year were included. Postoperative best-corrected visual acuity, intraocular pressure (IOP), cornea clarity, and integrity of the wound at last follow-up were noted.

RESULTS

Out of the 20 patients, 15 (75%) were males and 5 (25%) were females. The mean age was 42.6 ± 22.4 years. All 20 patients had a penetrating injury, with four (20%) injured by a stick, two (10%) by an iron rod, three (15%) due to road traffic accident (RTA), three (15%) by glass, and eight (40%) with other nonspecific objects [two (10%) with needle, two (10%) with elastic rope, two (10%) with bangle, and two (10%) with metal]. The average time between the injury and the surgery was 48 hours (2 days). Four (20%) patients underwent a second surgery within a week of repair. After limbal tear repair, at final follow-up at 3 years, 7 (35%) had VA worse than 20/800, 3 (15%) had VA between 20/100 and 20/800, and 10 (50%) achieved VA better than 20/80.

CONCLUSION

Preoperative visual acuity (VA), mode of injury, and size of wound affect the final visual outcome after surgical repair of limbal corneal laceration. Preoperative VA and mode of injury were statistically significant even in the multivariate analysis.

摘要

目的

在印度南部的一家三级眼科中心确定影响角膜缘裂伤手术修复后视力结果的因素。

方法

对 2011 年至 2021 年间诊断为角膜缘撕裂的患者进行回顾性分析。记录人口统计学信息，如年龄、性别、损伤原因和撕裂大小。进行全面的眼部检查，包括在没有详细的后段评估禁忌证的情况下进行温和的 B 扫描评估。仅纳入随访时间至少一年的病例。记录术后最佳矫正视力、眼压 (IOP)、角膜清晰度和最后一次随访时伤口的完整性。

结果

20 例患者中，15 例（75%）为男性，5 例（25%）为女性。平均年龄为 42.6±22.4 岁。所有 20 例患者均为穿透性损伤，其中 4 例（20%）为棍棒伤，2 例（10%）为铁杆伤，3 例（15%）为道路交通伤（RTA），3 例（15%）为玻璃伤，8 例（40%）为其他非特异性物体伤[2 例（10%）为针伤，2 例（10%）为弹性绳伤，2 例（10%）为手镯伤，2 例（10%）为金属伤]。受伤与手术之间的平均时间为 48 小时（2 天）。4 例（20%）患者在修复后一周内进行了第二次手术。在角膜缘撕裂修复后，3 年的最终随访时，7 例（35%）视力低于 20/800，3 例（15%）视力在 20/100 至 20/800 之间，10 例（50%）视力优于 20/80。
