Effectiveness of broadcasting guidelines for photosensitive seizure prevention.

Emissions from TV programs are a dangerous light source for photosensitive individuals, because 48.9% of patients have photosensitive seizures caused by TV programs. The authors used a national survey to verify the effectiveness of current Japanese guidelines, which are based on neurophysiologic principles of photosensitivity. They show that the guidelines successfully control TV images to protect many photosensitive persons from harmful TV emissions.
