Patients suffering from a traumatic brain injury (TBI) show many types of visual dysfunctions, including binocular, oculomotor, accommodative and visual field loss. This study evaluates the visual status of patients suffering a mild TBI.
The visual findings of a control group of 16 non-TBI patients are compared to the visual findings of 16 patients with documented mild TBI. Functions compared include symptomology, refractive status, stereopsis, ocular alignment by cover test, relative accommodation, pursuits, near point of convergence break and recovery, phorias at distance and near and vergence ranges at distance and near.
Significant differences were found between the two groups in the areas of refractive status, near point of convergence break/recovery, near cover test, stereo acuity and base-in break at distance. There were also significant differences in symptomology, pursuit function, base-in recovery at distance, base-in break/recovery at near and base-out recovery at distance.
In-depth visual evaluation of mild TBI patients is critical for documentation purposes as well as for possible treatment regimens.
创伤性脑损伤(TBI)患者表现出多种视觉功能障碍,包括双眼、眼球运动、调节和视野丧失。本研究评估轻度TBI患者的视觉状况。
将16名非TBI患者的对照组视觉检查结果与16名有轻度TBI记录患者的视觉检查结果进行比较。比较的功能包括症状、屈光状态、立体视、遮盖试验的眼位、相对调节、跟踪、集合近点的破裂和恢复、远距离和近距离的隐斜以及远距离和近距离的聚散范围。
两组在屈光状态、集合近点破裂/恢复、近距离遮盖试验、立体视敏锐度和远距离内收破裂方面存在显著差异。在症状、跟踪功能、远距离内收恢复、近距离内收破裂/恢复和远距离外展恢复方面也存在显著差异。
对轻度TBI患者进行深入的视觉评估对于记录目的以及可能的治疗方案至关重要。
