päivänvaloherkky

Päivänvaloherkky, also known as photosensitivity or photophobia, is a medical symptom characterized by discomfort or pain in the eyes when exposed to light, particularly bright light. This sensitivity can range from mild annoyance to severe, debilitating pain. It is not a disease in itself but rather a symptom that can be associated with a variety of underlying conditions.

Common causes of päivänvaloherkky include migraines, where it is a frequent accompanying symptom, often intensifying during a migraine attack. Eye conditions such as conjunctivitis (pink eye), keratitis (inflammation of the cornea), uveitis (inflammation of the middle layer of the eye), and iritis (inflammation of the iris) can also lead to light sensitivity. Certain neurological disorders, including meningitis and encephalitis, can present with photophobia. Even less serious issues like dry eye syndrome or eye strain from prolonged screen use can contribute to discomfort in bright light.

In some instances, medications can cause photosensitivity as a side effect, making the skin or eyes more susceptible to damage from UV radiation. Diagnosis typically involves a thorough medical history, a physical examination, and often an eye examination by an ophthalmologist to identify the root cause. Treatment strategies are aimed at addressing the underlying condition and managing the symptom. This may involve wearing sunglasses, using tinted lenses, avoiding bright lights, and treating any identified eye or systemic diseases.
