Light sensitivity, or photophobia, is one of the most commonly reported symptoms following traumatic brain injury (TBI). Despite how frequently it occurs, it remains one of the least documented and least understood issues in clinical and legal settings.

Many patients with TBI report difficulty in bright environments, discomfort using digital screens, and problems driving at night. These symptoms are real and often debilitating, even when they don't appear on imaging.

Functional impacts attorneys should understand

Photophobia can interfere with a person’s ability to work, communicate, and navigate public spaces. Common challenges include:

  • Limited screen use for professional or personal tasks

  • Difficulty walking outside without sunglasses

  • Trouble driving after dark due to glare from headlights

These limitations may prevent individuals from returning to their job or maintaining daily responsibilities—key considerations in cases involving loss of income or reduced quality of life.

Why visual symptoms go unrecognized

A clinical blind spot

In many cases, photophobia is underdiagnosed because it falls between specialties. Neurologists often focus on cognitive deficits, while ophthalmologists may concentrate on structural eye damage. As a result, light sensitivity is frequently left unaddressed in medical records.

Legal relevance

Attorneys should be aware that photophobia, even when undocumented in early care notes, may still be substantiated through a detailed ophthalmologic or neuro-visual exam. When explained clearly, this symptom provides a credible and understandable reason for ongoing functional limitations.

Distinguishing between ocular and neurological photophobia

When eye trauma is involved

Photophobia may result from direct injury to the eyes, such as inflammation, corneal abrasions, or orbital fractures. These cases require a careful review of trauma history and a targeted eye exam.

When the brain is the source

In most TBI cases, light sensitivity stems from the brain. The underlying mechanisms are not fully understood, but the pattern is consistent. Patients report similar experiences even when ocular exams and imaging appear normal. This suggests a neurologic origin that can still have a significant functional impact.

Strengthening a case with visual evidence

Including documented visual symptoms in a TBI case can help build a more complete and persuasive argument. Photophobia:

  • Demonstrates a tangible impact on daily function

  • Clarifies why a client may be unable to resume work

  • Makes the effects of an invisible injury easier for a jury to understand

Clear, accessible language in expert reports can connect the medical findings with the client's lived experience.

Key takeaways for legal teams

Photophobia can be a daily barrier to normal life. For individuals recovering from head trauma, it affects productivity, independence, and comfort. Legal professionals handling TBI cases should not overlook the role of light sensitivity, especially when it aligns with broader post-concussive symptoms.

A trauma-informed ophthalmologic review can uncover the visual effects of brain injury and support a stronger, more complete legal case.
