Objective

With the increasing global prevalence of acquired brain injury (ABI), the burden of visual problems as a sequelae to ABI is on the rise. This study reports the visual profile of patients with ABI seen in Neuro-Optometry Clinic (NOC) at a tertiary eye-care center in Southern India.

Methods

A retrospective study was carried out between January 2014 and December 2015. Medical records of patients diagnosed with ABI referred by Neuro-Ophthalmologists to the NOC were reviewed. The detailed history, clinical findings of neuro assessment and management details were recorded.

Results

Of the 241 patients with ABI, 208 had Traumatic Brain Injury (TBI) and 33 had Cerebro-Vascular Accident (CVA). The mean (SD) age of patients with TBI was 35 ± 14 years and CVA was 52 ± 16 years. Binocular diplopia (61%) was seen predominantly in TBI due to vertical deviation (31%). Cranial nerve palsy was most common in TBI (55%) than CVA (36%) and visual field defects were most frequently seen in CVA (27%).

Conclusion

Cranial nerve paresis and restrictive strabismus with diplopia were the most common presentations in TBI and visual field defects in CVA. A neuro-optometric evaluation is recommended to identify visual dysfunctions and provide appropriate management options.

印度队列中获得性脑损伤的视觉特征：一项回顾性研究。

目的

随着获得性脑损伤（ABI）的全球普及率的提高，作为ABI的后遗症，视觉问题的负担正在增加。这项研究报告了印度南部一家三级眼保健中心在神经验光诊所（NOC）中看到的ABI患者的视觉特征。

方法

在2014年1月至2015年12月之间进行了一项回顾性研究。对神经眼科医师转诊给NOC的诊断为ABI的患者的病历进行了回顾。记录详细的历史，神经评估的临床发现和管理细节。

结果

在241例ABI患者中，有208例发生颅脑外伤（TBI），而33例发生了脑血管意外（CVA）。TBI患者的平均（SD）年龄为35±14岁，CVA为52±16岁。由于垂直偏差（31％），主要在TBI中发现双眼复视（61％）。TBI（55％）比CVA（36％）最常见于颅神经麻痹，CVA（27％）最常见于视野缺损。

结论

颅神经轻瘫和限制性斜视合并复视是TBI和CVA视野缺损的最常见表现。建议进行神经验光评估，以识别视觉功能障碍并提供适当的管理选项。
