Symptom 9: Photophobia: A Light Intolerance in CSFL
Photophobia, or an extreme sensitivity to light, is a common symptom experienced by individuals with a cerebrospinal fluid leak. It isn’t just about squinting in bright light; it’s a discomfort that persists and impacts the person’s daily life.
Cerebrospinal fluid helps maintain an optimal environment for the brain to function. When this fluid leaks, the brain’s position and pressure dynamics change, leading to symptoms like photophobia.
In people with a CSF leak, they might find sunlight or bright indoor lights unbearable. This can lead to excessive squinting, watering of the eyes, or the need to wear sunglasses even indoors. It’s not a mere inconvenience but a symptom that limits their daily activities.
Photophobia can also cause headaches or exacerbate existing ones. This adds to the discomfort and can significantly impact the person’s quality of life. Everyday tasks like reading, using a computer, or driving can become difficult. (9)
