After a concussion or mild traumatic brain injury (mTBI), patients often suffer from light sensitivity, or photophobia, which contributes to decreased quality of life post-mTBI. Whereas sunglasses may provide some relief from photophobia, they are not practical indoors or in low light. A light-mitigation strategy can be easily used indoors as needed to optimize the relief. We have found that many photophobic patients experience relief using colored sunglasses.
To provide the athletic trainer with a means and method to assess whether an athlete is suffering from photophobia after concussion and to determine if colored glasses provide relief.
Cross-sectional study.
Rehabilitation clinic.
Fifty-one patients being treated after concussion.
INTERVENTION(S): We assessed postconcussion patients for visual symptoms including photophobia and photosensitivity. Off-the-shelf glasses were used to determine whether specific colors provided relief from photophobia. Screening was done using a penlight and multiple pairs of colored glasses.
MAIN OUTCOME MEASURE(S): Self-reported mitigation of photophobia symptoms and the specific color frequency that reduced symptoms in each individual.
Of the 39 patients studied who had visual symptoms, 76% complained of photophobia. Using glasses of 1 or more colors, symptoms were relieved in 85% of patients reporting photophobia. The colors that provided the most relief were blue, green, red, and purple. No adverse events were reported.
An empirical assessment of frequency-specific photophobia is easy to perform. A traditional penlight is used to elicit photophobia and then the colored glasses are tested for optimal relief. Frequency-specific photophobia can be reduced with a strategy of light-mitigation therapy, including colored glasses, sunglasses, hats, and light avoidance. This, we believe, helps to improve the patient's quality of life and may aid in the recovery process. More work is needed to identify the best colors and methods of mitigating frequency-specific photophobia.
在脑震荡或轻度创伤性脑损伤（mTBI）后，患者经常会出现畏光症状，这会导致mTBI后生活质量下降。虽然太阳镜可能会缓解畏光症状，但在室内或光线较暗的环境中并不实用。一种减轻光线的策略可以根据需要在室内轻松使用，以优化缓解效果。我们发现，许多畏光患者使用有色太阳镜后症状得到缓解。
为运动训练师提供一种方法，用于评估运动员在脑震荡后是否患有畏光症，并确定有色眼镜是否能缓解症状。
横断面研究。
康复诊所。
51名脑震荡后接受治疗的患者。
我们评估了脑震荡后患者的视觉症状，包括畏光和对光敏感。使用现成的眼镜来确定特定颜色是否能缓解畏光症状。使用手电筒和多副有色眼镜进行筛查。
自我报告的畏光症状缓解情况以及每种颜色减轻症状的具体频率。
在研究的39名有视觉症状的患者中，76%抱怨有畏光症状。使用1种或更多颜色的眼镜后，85%报告有畏光症状的患者症状得到缓解。缓解效果最佳的颜色是蓝色、绿色、红色和紫色。未报告不良事件。
对特定频率畏光症进行实证评估很容易进行。使用传统手电筒引发畏光症状，然后测试有色眼镜以获得最佳缓解效果。通过包括有色眼镜、太阳镜、帽子和避免光线在内的减轻光线疗法策略，可以降低特定频率的畏光症。我们认为，这有助于提高患者的生活质量，并可能有助于康复过程。需要更多的研究来确定减轻特定频率畏光症的最佳颜色和方法。
