Valoherkkyys, also known as photophobia, is a medical term that describes an abnormal intolerance to light. This condition is not a disease in itself but rather a symptom that can arise from various underlying causes. Individuals experiencing valoherkkyys find ordinary levels of light to be uncomfortable or even painful. This discomfort can manifest as a stinging or burning sensation in the eyes, headaches, or an involuntary squinting response.

The causes of valoherkkyys are diverse. It can be associated with certain eye conditions such as uveitis, keratitis, or iritis, which involve inflammation within the eye. Migraine headaches are a common trigger for photophobia, with many individuals experiencing heightened light sensitivity before, during, or after an attack. Neurological conditions like meningitis or encephalitis can also present with valoherkkyys as a symptom. Additionally, certain medications, particularly those that affect pupil dilation or are known to cause ocular side effects, can lead to increased light sensitivity. Even simple factors like eye strain or dry eye syndrome can contribute to temporary photophobia.

Diagnosis of valoherkkyys typically involves a thorough medical history and a comprehensive eye examination. Identifying the underlying cause is crucial for effective management. Treatment strategies vary depending on the root issue. For instance, if valoherkkyys is due to an infection or inflammation, antibiotics or anti-inflammatory medications may be prescribed. For migraines, appropriate headache treatments are recommended. In cases where no specific underlying disease is found, managing symptoms may involve wearing sunglasses, using anti-glare computer screens, and minimizing exposure to bright lights.
